Definitions
- the present invention relates to the field of netting for wrapping spoilable (perishable) items and a method of substantially reducing spoilage of the spoilable items by wrapping the spoilable items with the netting, and more particularly, by wrapping bales using a baling apparatus with the netting.
- balers for baling agricultural crops into "round" bales referring to a generally cylindrically shaped bale having a generally round cross-section
- the first round-balers also used various types of twines to secure the bale, however, over the years different types of netting have been used.
- the use of netting, and in particular, knitted Raschel netting, has become more and more common.
- Raschel netting is a knitted netting that typically is made from polymeric material and includes a plurality of equally spaced longitudinal ribbons known as "franzes" and a plurality of intervening zigzag ribbons known as "schusses.”
- the netting used including Raschel knitted netting, is primarily open, with the franzes and schusses only making up a small percentage of the surface area of the bale and does not protect the bales from rain.
- Plastic film wrap including "sticky film” wrap has been used to wrap whole bales or portions of bales, with the goal of protecting a bale from rain.
- impermeable plastic film wrap does not allow moisture already within a baled crop to escape therefrom, since it is bound by an impermeable plastic layer. Since the inherent moisture level in baled crops may be on the order of one or more dozen percent of weight of the crop (for example, in baled hay), this bound-in humidity easily promotes spoilage of the baled crop.
- bales are often left in a field, exposed to weather for a year or more, cumulative rain and/or ground moisture penetration may be significant, as may be the resultant crop spoilage.
- U.S. Patent No. 4,703,605 to Ackerman describes a bale and baling process using a netting material with water impermeable portion(s) formed from water impermeable foil.
- the net and water impermeable portions are not attached to one another, but are fed from either separate rolls, or alternatively are a single piece of material, in which holes are created to form a netting in certain areas, leaving other areas completely sealed off to protect the bale from moisture.
- Ackerman only covers the bale partially with the water impermeable portion. In Ackerman, only the top, or the top and bottom are covered with such plastic.
- German Patent No. DE 3525294 (DE '294) describes a wrapping material for bales having a "watertight film" arranged in a central portion of a netting material.
- the watertight film has a length equal to at least half the circumference of the bale. No indication is given that it should be anything substantially more than about 1/2 the circumference of the bale.
- This watertight film is welded or glued to the net "point by point.”
- the netting and the film are fully attached, thus the stretching characteristics of the net are transferred to the watertight film.
- DE ' 294 only covers about 1/2 the circumference of a bale, leaving the remainder of the bale exposed to the elements.
- German Patent No. DE 19833554 (DE '554) describes a pre-shaped bale cover for a pre-determined size of bale made up of segments of fiberglass netting attached end-to-end with plastic "foil" segments (note brackets 12 and 14). This end-to- end attachment of segments is significant because the tensile strength of the cover in DE '554 is limited to the weakest portion, which is likely to be the foil segments.
- EP 1321028 (EP '028) describes a baler and an enveloping apparatus. Separate rolls of net and sticky (stretch) film, which adheres to underlying net layers, are used. Thus, the layers are not attached to one another prior to assembly.
- WO 90/08708 describes a packaging material having breathable paper strip portions and a transparent window strip portion for forming packaging simultaneously with the insertion of a product into the packaging.
- the strips of the packaging material of WO 90/08708 are arranged side-by-side, attached along adjacent edges, each strip being continuous from the beginning of a roll, to the end of the roll of the material.
- Great Britain Patent No. GB 2348633 (GB '633) describes a laminated material in which film is laminated to a netting material.
- the net offers relatively greater strength than the film portion, but moisture cannot pass through the film portion, and attachment of an end portion of the netting to the bale, to prevent unraveling of the wrapping is difficult.
- negative synergy exists between the netting portion and the film portion. Such negative synergy is a result of, for example, introducing a relatively stretchable component (the film), with a comparatively less-stretchable component (netting).
- Typical stretch films for the memeposes of wrapping bales experience a reduction in width in connection with an increase in length (stretch). For example, a 16 cm wide film used for silage wrapping loses 32% of its width when lengthening 77%. Even if a laminated material has one component with less drastic properties, the laminate as a whole disadvantageously experiences the shape changes of the material with larger shrinkage ratios.
- the subject composite netting includes a continuous netting component, and a discontinuous, (e.g., panels, segmented or intermittent) breathable material component.
- the breathable material component is partially attached, or tacked, to the net.
- the breathable material is defined as a material that is substantially vapor permeable, and substantially liquid impermeable, particularly with regard to water vapor and liquid water.
- the breathable material is attached only along the leading edge of each breathable material panel. As a result of the attaching technique the stretching forces to which the netting is subjected are not transferred to the breathable material. Thus, each component of the netting retains its individual properties.
- Each breathable material panel is aligned with and proximate to or contiguous with a portion of the netting, and is of sufficient width to extend across the width of a bale, and of sufficient length to circumscribe the bale circumference a single time, or optionally with only a slight overlap.
- Each bale is initially wrapped with about one wrapping of the netting material of the composite netting. However, more or less netting is optional and not substantially detrimental to the function of the breathable material.
- the breathable material that is partially attached to the composite netting is then, in a continuum, wrapped around the bale with the adjacent netting section, which totals at least two netting layers and one breathable layer of material. After this, one or more additional netting layers may be applied if desired.
- the outermost netting layers are slit along a center line of the bale, causing these portions of the netting materials to spread over and cover the edges of the bale.
- the subject composite netting can be used as a single feed of composite material, which is pre-assembled, in a factory or the like, prior to mounting on a baling machine.
- the breathable material is attached to the netting at preselected intervals of the netting, and only a portion of the breathable material is attached, in some embodiments, along the leading edge of the breathable material. In this sense, the term "leading" is relative to a direction of feeding into the baling apparatus.
- the breathable material may be attached to the netting in any of a variety of manners, including by ultrasonic welding, adhesive tape, or a hot melt or other types of connections.
- the elongation and lateral shrinkage experienced with the netting during the baling process (which may be as high as about 10%), does not affect the length or width of the breathable material.
- the netting may be Raschel knitted or another suitable netting material.
- breathable material typically only one layer of breathable material is intended to cover the bale, so that the function of the breathable material is not impeded by excess material.
- extra layers may be used in accordance with the invention.
- each wrapping process will begin and end with netting, so that there will typically be three total layers of netting, one of which is adjacent to the breathable material portion.
- extra layers before and/or after the breathable material layer are employed. Typically, this embodiment would be used to provide increased strength for the wrapped bale.
- the breathable material extends only the width of the bale, while the net extends beyond the width of the bale, in order to facilitate covering the edge of the bale, particularly when the outermost layer of netting is split.
- the netting is dimensioned to extend over the edges of the bale, which allows the net to grip rough edges of a baled crop and thereby reduce the chances for unraveling of the net that can otherwise more easily occur.
- the netting is not able, in many instances, to grasp parts of the bale, since the net most effectively engages with the baled crop. If the breathable material prevents the netting from contacting the baled crop, the netting cannot engage therewith to prevent unraveling.
- the effectiveness of the netting grasping underlying layers of netting maybe impeded by the breathable material.
- the edges of the bale may be the only portion of the bale with which the netting can engage.
- the netting can spread and even more effectively cover and grip the edges of the bale, thereby preventing unraveling of the netting.

- Figures 9A-9O illustrate example, non-exhaustive alternative embodiments for attachment point locations for attaching a breathable material panel to a netting material in accordance with the invention.
- the subject composite netting 100 includes a continuous netting component 110, and a discontinuous, breathable material component 120.
- the breathable material component 120 is separated into panels 127 and though only two panels are illustrated in Figures 1 and 2, it is to be understood that the netting is continuous and has a substantially repeating pattern.
- the breathable material panels 127 are spaced along the continuous netting material 110 at preselected intervals, which relate to a circumference of a bale to be wrapped.
- one breathable material panel 127 wraps one bale, one time, and accordingly has a length substantially equal to the circumference of the bale to be wrapped.
- one layer of breathable material 120 is intended to cover the bale, so that the function of the breathable material 120 is not impeded by excess material.
- extra layers rnay be used in accordance with the invention.
- the netting material 110 is a Raschel knitted netting, and in other embodiments, another suitable netting material is used.
- a suitable netting material has sufficient longitudinal strength to hold a bale together.
- a suitable netting material also prevents unraveling of the netting 100 from the wrapped bale, and allows attachment of the breathable material panels 127 with minimal difficulty.
- the breathable material 120 is a fused polyethylene material, (e.g., Tyvek(R)).
- the breathable material 120 comprises non-woven materials such as SMS (styrene/alpha-methylstyrene), spunbound materials, meltblown materials or the like.
- SMS styrene/alpha-methylstyrene
- the breathable material 120 may also comprise a breathable film, microperforated film, or a multi-layer breathable sheet including any of the aforementioned materials and/or other materials.
- the width of breathable material 120 is, in a preferred embodiment, substantially equal to a width of a bale to be wrapped. In other embodiments, however, the width of the breathable material maybe wider or narrower than the width of a bale.
- the netting material 110 may also be less than, equal to, or greater than the width of a bale to be wrapped. However, in a preferred embodiment, the netting material 110 is slightly wider than the bale to be wrapped, to facilitate the netting material 110 gripping edges of the bale. Accordingly, in a preferred embodiment, the netting material 110 is slightly wider than the breathable material portion 120.
- the netting 100 is manufactured so as to have a plurality of wrapping portions 140, each wrapping portion being for wrapping a single bale, and having at least three sections.
- the first section 141 of each wrapping portion consists essentially of a netting 110.
- This first wrapping section 141 is continuous with the netting of the second wrapping section 143, which additionally has a breathable material panel 127 partially attached thereto.
- the third wrapping section 145 is again continuous with the netting 110 of the second wrapping section 143, and itself consists essentially of a netting 110.
- third wrapping section 145 may only be as long as required to secure the end of the wrapping portion 140 to the wrapped bale via the underlying layers of netting 110 and breathable material 120.
- third wrapping section 145 may be approximately the circumference of the bale, or longer, if increased strength or another result are desired.
- Additional wrapping sections may be added following the third wrapping section, which may include additional features. Such additional features may include indicators that allow the bale to be seen from a distance.
- the subject composite netting 100 uses a single feed of composite material, which is pre-assembled, prior to mounting on a baling machine. That is, the breathable material is not on a separate roll, and separately fed into the baling machine.
- the breathable material 120 is attached to the netting material 110 along the length of the netting material at preselected intervals. Only a portion of each breathable material panel (or "segment") 127 of the breathable material component is attached to the netting material 110.
- the breathable material panel 127 is attached to the netting material 110 so that it lays substantially contiguously with the netting material 110 when formed in a roll, during the wrapping process, and while wrapping a bale.
- the breathable material panels 127 and the netting material 110 are preferably in an abutting relationship throughout the length of the breathable material panel 127.
- breathable material layer 120 Of primary importance for the attachment between the breathable material layer (or “component”) 120 and the netting material (or “component”) 110, is that relative movement between the breathable material layer 120 and the netting material 110 is allowed to occur, particularly during the wrapping process. It is necessary that any movement due to elongation (stretching) and narrowing of netting 110 during the baling process is not transferred to the breathable material 120. Instead, the layers of netting 110 and breathable material 120 must be able to move past one another to some degree when dimensional changes occur, such as during a baling operation. Accordingly, any attachment that allows this to occur is likely suitable. Among these, connectors that physically restrain the breathable material panel 127 to the netting material are desired. Though physically restrained, movement is allowable, thus a "slide-able" connector, a connector having some amount of slack or stretch, or the like is applicable.
- Figures 9A- 90 illustrate various possible connection points (or attachment regions) between the breathable material panel 127 and the netting material 110. Because the breathable material 120 will typically have some degree of stiffness, attachment to the netting material 110 need not always be only along a leading edge 125 of the breathable material panel 127 (as shown in Figures 9 A, 9B, 9C, 9D and 9J). Instead, due to this "stiffness," attachment points may be arranged at points either along a leading edge, along a side edge or edges (as shown in Figures 9E-9I), toward a center of a breathable material panel 127 (as shown in Figures 9L- 9N), or any location where attachment minimally interferes with relative longitudinal and lateral stretching of the components.
- the breathable material panel 12 is partially attached to the netting material 110, only along, or very near the leading edge 125 of each breathable material panel 127. In this sense, the term "leading" is relative to a direction of feeding into the baling machine.
- Figure 9A illustrates three attachment points 910 distributed evenly across the leading edge 125 of the breathable material panel 127. If the narrowing of the netting material 110 is not significant, then this arrangement of attachment points 910 will effectively allow movement between the components.
- FIG 9B similarly shows attachment on the leading edge, but only includes two attachment points, eliminating the center point of attachment as compared with the embodiment of Figure 9 A.
- Figure 9C also illustrates attachment along the leading edge 127 of the breathable material panel 127, but in this embodiment, attachment points 910 are located proximate to each other and near a central axis of the netting material 110.
- Such arrangement of the attachment points provides control over the orientation by restricting longitudinal and lateral slippage of the breathable material panel 127 relative to the netting material 110, and also prevents relative rotation, since the plurality of points illustrated, more effectively prevents rotation than a single point.
- Figure 9D also illustrates proximately arranged attachment points 910, but in this embodiment, they are oriented substantially axially, relative to a central axis of the netting material 110. Depending on the specific application, this arrangement may be preferable, as any lone change in width will not affect the breathable material panel 127. Moreover, since elongation (or "stretching") is cumulative, the nearer the attachment points 910 are placed relative to each other, the lower a magnitude of stretching will be that is experienced. This concept also holds true for lateral stretching or contraction when the attachment points 910 are arranged substantially perpendicular relative to a central axis of the netting material 110.
- FIG. 9D illustrates one example alternative shape of the breathable material panel 127. However, still other shapes are possible, and may be selected to achieve various effects.
- Figures 9E-9G and 91 illustrate attachment points 910 arranged along one edge 925 of the breathable material panel 127. Some internal stiffness of the breathable material panel 127 is necessary to ensure that, as the netting 100 travels into the baler, that the central attachment points 910 sufficiently maintain the leading edge 125 of the breathable material panel 127 substantially proximate to the netting material 110.
- Figure 9H illustrates attachment points along two opposite lateral edges 925 of the breathable material panel 127.
- Figures 9H-9K illustrate attachment regions 911 in the shape of strips arranged along one or more edges of the breathable material panel 127. In the case of the embodiments of Figure 9H, the attachment regions 911 are arranged on opposite sides of the breathable material panel 127.
- the attachment region 911 is only along a portion of one lateral edge of the breathable material panel 127.
- the attachment region 911 is a strip along the leading edge of the breathable material panel 127.
- the attachment regions 911 are along the leading edge 125 and the opposite trailing edge of the breathable material panel 127.
- Figures 9L- 9N illustrate attachment points 910 arranged substantially in a center of the breathable material panel 127, near a central axis of the breathable material 110. As with the above embodiments, if the attachment points 910 are sufficiently close to one another, any movement due to elongation will not substantially affect the breathable material panel 127.
- some internal stiffness of the breathable material panel 127 is necessary to ensure that, as the netting 100 travels into the baler, that the central attachment points 910 sufficiently maintain the leading edge 125 of the breathable material panel 127 substantially proximate to the netting material 110, so that it is wrapped around the bale in the proper orientation, and is not caught by a component of the baler and prevented from properly being wound around a bale (or other item).
- the embodiment of Figure 90 illustrates a breathable material panel 127 having an oval shape, and attachment points 910 arranged substantially along the contour of the leading edge of the breathable material panel 127.
- the attachment points 910 need not necessarily be “points” or “dots” as illustrated, but may be in any form , and of any size suitable for providing adequate attachment strength and material characteristics of the composite netting material.
- the breathable material 120 may be attached to the netting material 110 in any of a variety of manners, such as by fusing through ultrasonic welding, heat welding or solvent welding, by adhesives such as adhesive tape, hot melt or by other types of adhesives or connectors.
- attachment elements may be used, such as hooks, wires, including twist ties and wire rings, strings, elastic elements, including elastic strings, straps of plastic, paper ties or another material.
- attachment means may include knitting processes. Since it is only necessary for the attachment elements to hold the breathable material panels 127 to the netting material 110 during the wrapping process, if the attachment elements are made from a relatively easily degradable material such as paper, no detrimental effects would be realized. This is because by the time rain or other climate conditions would affect the degradable material, the breathable material would already be bound by the netting material 110 on the bale.
- every breathable material panel 127 be attached to the netting material by the same means. While typically such an arrangement would be easiest to manufacture, there are no functional reasons for not using different attachment modes for different breathable material panels 127. It should also be noted that a single breathable material panel 127 may, if desired, be attached to the netting material 110 by multiple modes (e.g. by an elastic string and fused portions).
- the breathable material 120 extends only the width of the bale, while the netting material 110 extends beyond the width of the bale, in order to facilitate covering the edge of the bale, which is doubly advantageous when the outermost layer of netting material 110 is split and wraps around the edge of the bale. In embodiments where the netting material 110 is dimensioned to extend over the edges of the bale, this allows the net 100 to grip rough edges of a baled crop and thereby reduce the chances for unraveling of the net 100 that might otherwise more easily occur.
- the breathable material 120 can be wide enough to cover all or a portion of the sides of the bale, in addition to the circumference of the bale to fold over the edges and additionally protect the bale from exposure to moisture.
- Each bale is initially wrapped with about one full wrapping of the netting material 110, corresponding to the first wrapping section 141.
- the length of the first wrapping portion is therefore substantially equal to the circumference of the bale, though variations from this length are possible to produce the desired result.
- Use of less netting could be desirable in instances where cost savings are an issue.
- a desire for increased strength is a main reason for use of more net.
- more or less netting 110 may be applied to the bale to increase the strength of the wrapping, or for other desired effects. Since the netting 110 is largely an open mesh, additional layers do not substantially impede the function of the breathable material 120.
- the second wrapping section 143 with its breathable material panel 127, partially attached to a respective portion of the netting material of the second wrapping section 143, is then wrapped around the bale with its adjacent netting section.
- the result is that approximately two netting layers and one breathable material layer surround the bale. If the breathable material panel 127 has been attached to the underside of its adjacent netting portion, (relative to being wound on the bale), then the order of layers, relative to the surface of the bale, is: net - breathable material - net.
- the breathable material panel 127 has been attached to the top side of its adjacent netting portion, (relative to being wound on the bale), then the order of layers, relative to the surface of the bale, is: net - net - breathable material. It should be understood that the aforementioned example combinations of netting and breathable material layers are not intended to be exhaustive or limiting, but are to serve as example arrangements.
- the third wrapping section 145 is wrapped around the bale.
- the third wrapping section 145 consists essentially of netting, and thus may surround the bale as many times as desired to secure the bale. However, in many instances, it is not necessary to wrap the bale fully to achieve a secure bale.
- a fourth or further additional layer of netting may be applied to the bale, if desired, to achieve increased strength or for other objectives.
- the outermost netting layers 110 are slit substantially along a center line of the bale, causing these portions of the netting material to spread over and cover the edges of the bale. Since the netting is somewhat stretched during the baling process in order to provide the required tension for holding the bale together, the netting on the bale includes internal tension from the stretching that occurs. When the netting is split along a centerline, the internal forces within the netting cause the netting to shift and cover each of the edges of the bale. Naturally the extent to which this occurs depends on the specific type of netting 110 used. This method is particularly applicable to use of Raschel knitted netting.
- FIGS 3 a and 3b illustrate a cross-section of a wrapped bale in accordance with the invention.
- the breathable material 120 is mounted on a face of the netting material 110 that is placed against the bale 310, what is essentially a first layer of netting will contact the bale 310 at a first level.
- This netting corresponds to the first wrapping segment 141, and may comprise slightly more or less than one complete circumference of wrapping, as desired.
- Above this layer is a breathable material from the second wrapping section 143, and, above that is the netting material 110 of the same second wrapping section 143, which is partially attached to the breathable material 120.
- the breathable material surrounds the bale only one time, though a slight overlap is allowable. However, as stated above, if the properties of a chosen breathable material are such that more than one layer does not detrimentally affect the function of the breathable material, then more than one layer may be utilized. >
- Figures 4 and 5 a are isometric views and Figure 5b is a front view, illustrating a bale 310 wrapped in the subject composite netting material 100, following a step where the outermost layer of netting 110 is split.
- the netting contracts, and the cut edges 115 move toward the edges 315 of the bale 310.
- the breathable material 120 is not cut, and remains to protect the baled crop from excess moisture. Since the outer layers of netting 110 still remain partially on the circumference of the bale, the netting 100 still helps hold the bale together, and hold the breathable material 120 to the bale 310.
- the netting 110 With the netting 110 covering the edges 315 of the bale 310, the netting 110 further grips the edges 315 of the bale 310. In part, the netting 110 engages the rough surface of the bale 310, becoming partially entangled in the baled crop itself. Thus, the edges of the bale 315 are additionally held in by the netting 110, and the netting 110 is additionally prevented from undesirably unraveling.
- FIGs 6, 7a, 7b and 8 illustrate example alternate embodiments of arrangements of breathable material 120 on a continuous netting material 110.
- the breathable material panels 120 are attached to the netting portion. Partial attachment along a leading edge is preferable for the mode of attachment.
- elongation of the netting material 110 during baling which will result in a lateral shrinkage, will less adversely affect this arrangement of breathable material panels.
- the breathable material panels 120 are arranged in relatively narrow strips along a width of the netting material 110. Thus, when wrapping a bale, it will appear to be striped. The bale may be left with such a covering if only partial protection from the elements is desired. However, a complete covering is achieved in these embodiments when two layers of breathable material are covering the bale. These layers, however, only slightly overlap each other since the breathable material 120 is arranged in panels that are offset from one another, only overlapping slightly, if at all.
- inventions of Figures 6 and 8 differ in the placement of overlapping sections of breathable material 120 panels.
- the embodiment of Figure 6 includes a section of netting material 110 between sections of breathable material 120 panels
- the embodiment of Figure 8 includes two offset sections of breathable material 120 panels arranged adjacently, to one another on the continuous netting material 110.
- Figures 7a and 7b are variations of Figures 6 and 8, in which larger panels of breathable material 120 are used.
- the breathable material 120 panels are set apart from each other, covering the entire width of the bale in combination when both are wrapped around the bale.
- the breathable materials are contiguous along their edges, but offset slightly so that one portion begins and ends before the other, relative to feeding into a baler.
- each wrapping of breathable material 120 only covers approximately half of the surface area of the circumference of the bale.
- the subject netting material for use in wrapping bales of agricultural produce, the invention may advantageously be applied to wrapping other spoilable items.
- the subject netting material for example, can be used to wrap spoilable items such as fruits, vegetables or plants that are on pallets, in preparation for shipping. Additionally, substantially rectangular bales, as well as substantially cylindrical bales can advantageously be covered with the subject composite netting material.
