Abstract

The needle pack includes a needle pocket (2) of paper or flexible plastic to take needle grips (6). It consists of a strip of the material with one end folded over the needle shafts and connected to the center section at the edges, on which the needle grip lies. The connection is made flat between the pocket sector (15) and the center sector. The strip connecting points hold the needles close together.

Description

The invention relates to a method for packaging elongated flattened elements, such as knitting machine needles, a needle pouch and a needle packaging with such a needle pocket.

Knitting machine needles are usually larger Quantity sold. There are several such needles which are grouped together as a "handle" or "needle handle" be packed together. These are to a handful of needles, as you would the fitter may be needed several times to create a needle bed with needles to equip. Such needles have so far been used, for example, in Paper bags are delivered, pre-made and then at the end the needle production with needles and then closed become. For very specific applications and thus the Needles in the bag won't fall apart, they will previously grouped together, for example, with a rubber band, which is then inserted into the bag as a bundle.

This type of packaging is relatively complex. Moreover can not be completely excluded that the needles falling apart in the paper bag. For example this is the case when someone removes the rubber band, the needles then put it back in the bag.

If the needles are inserted loose, unbundled into the bag, they fall apart in the bag and can only be disordered be removed.

Based on this, it is an object of the invention to provide a needle packaging to create the orderly inclusion of a Needle grip allowed with simple technical means.

This object is achieved with the needle pocket according to claim 1 solved. The needle pocket according to the invention consists of a Strip of paper, one folded and two striped Areas connected to the rear end. This end forms a pocket section. Between the two strip-shaped connection areas is one Bag formed from which a needle handle can be picked up can. If the width of the bag and the The width of the needle handle on each other will make the needles without other fasteners reorganized in the needle pocket. They are then aligned parallel to each other. In there are no other holding devices in the needle pocket - the needles are only held by the Needle bag are spanned.

Such a needle pocket can be particularly simple Create way. Production can take place during assembly done with the needles as proposed in claim 20. According to this claim, the needle pocket is created by a Needle grip on a strip of flexible material, for example a paper strip, placed lengthways, after which a End of the strip on the elongated elements, i.e. e.g. the Knitting needles, laid and connected to the stripe at the edges becomes. The connection areas are preferably used made so wide that it extends from the outer edge of the Stripe extend to the beginning of the pocket, which Hold the needle handle together. The pocket end of the strip-shaped connection area is the point on which the first and last needle of the needle handle are held is.

This type of packaging can be automated very easily and without changing the width of the strip of flexible Apply material to needle handles of different sizes. In other words, the packaging can be or paper tape of a given width and any length can be used for the packaging of most needles. While of the packing process are from the endless belt each Cut off sections of the required length. The Length depends on the length of the needles. But there are Very large tolerances are permitted because the cover section of the The strip can be placed anywhere on the pocket section be attached.

Another advantage is that the needle handle from the Bag or the recording room is held together. The needles or other elongated, flat side by side Elements are arranged or lined up in the needle packaging.

Another advantage is that after opening the lid part the needle ends are exposed for gripping. from that this results in easy handling of the packaging and the Needles. The needles can be sorted and removed become. Aligned means that the feet of all needles are in point in a given direction. This improves handling in the maintenance of knitting machines.

The cover section can, for example, with an adhesive or adhesive label can be attached to the pocket section. In addition to its function as a sealing tab, the adhesive label can also be used still take over the function of the data carrier. It can also be used as a seal and thus as a tamper-evident seal serve.

The flexible material from which the strip is made can be equipped with an anti-corrosion agent. For example the strip can consist of a soaked paper. It is also possible to use plastic or plastic strips a plastic-impregnated or plastic-coated Making paper. Plastic coated paper or Plastic has the advantage of being weldable. The stripe-shaped Connection areas can thus by a Welding process. For example, it can also suffice, only the connection areas with one Coating, for example with a thermal adhesive provided, the connection for example by exposure to ultrasound will be produced.

The packaging process can be fully automated. This applies in particular to the possibility the packaging of needles of different widths and different Length as well as of needle handles of different sizes one and the same strip. The width of the needle handle can be adjusted by the width of the connection points. The Length of the needle handle can be determined by cutting the Strip of the specified length of the same.

The method according to the invention comes without pre-assembled Bags, which can eliminate manual labor and packaging costs can be lowered.

The well-aligned storage of the needles or other Items in the needle pocket gives a good mechanical Protection of the elements. The packaging is particularly simple and can be produced without waste.

As mentioned, the connection areas can be glued or welding. It is also possible, Provide crimping points where the two are flat on top of each other lying sections of the strip form-fitting with each other are connected by sections one at a time Partly pressed into recesses of the other part become. The advantage of such crimp connections is that Speed of manufacture, the low manufacturing effort and good recyclability.

The needle pockets described so far can with a appropriate box to a needle packaging to be captured, the one or more needle pockets and thus contains a larger supply of needles. The boxes are preferred mechanically resistant plastic boxes with cuboid interior. The bottom is rectangular and corresponds in size to the size of a needle pocket, i.e. their rectangular outer outline. This allows several Needle pockets one above the other in the interior of the plastic box be inserted, the orderly inclusion of the Needles in the needle pockets ensures that the needle pockets easily in the intended number one above the other let layered in the interior of the box without claiming too much height.

Further details of advantageous embodiments of the Invention emerge from the drawing, the description or from subclaims.

A needle packaging 1 is illustrated in FIG. 1, to the at least one, but preferably several needle pockets 2 and a box of 3 belong. Box 3, which is in Figure 1 is shown based on its lower part for example a plastic box that is open at the top and an all-round fold 4 for receiving a cover having. Their interior has a rectangular floor plan on, which corresponds to the rectangular outline of the needle pocket 2.

The needle pocket 2 is illustrated separately in FIG. 2. It is used for packaging knitting machine needles 5, each needle pocket 2 contains a so-called needle handle 6. A group of knitting machine needles is placed under the needle handle 5 given number (e.g. 50) understood. The Knitting machine needles 5 have flat sides with which they abut each other. The knitting machine needles 5 lie there ordered side by side. As can be seen from FIG. 3, each have an elongated shaft 7, the one end Carries hook 8, and an end 9 on which a foot 11 is formed is. In the area of the end 9 and the foot 11 is the Height of the knitting machine needle significantly larger than in the area of the shaft 7. As FIGS. 2 and 3 show, the Knitting machine needles 5 with the same shape and congruence on the side together.

The needle pocket 2 consists essentially of a single one Strips 12 of flexible material, such as Paper, anti-corrosive paper, plastic-coated paper, such as polyethylene-coated Paper, or plastic. The stripe 12 has a width that is significantly larger than the width of the largest expected needle grip. The needle handle 6 lies in a central section 14 of the strip 12. A pocket section 15 joins a bending line 16 the middle section 14. The from the bending line 16 to the Free edge 17 corresponds to the measured length of the pocket section 15 about the length of a shaft 7. The pocket section 15 lies, as FIG. 2 shows, on the shafts 7 of the knitting machine needles 5 and laterally next to the shafts 7 on the Middle section 14. This is the pocket section 15 forming a pocket 18 (Figure 8) with the central section 14 connected. Strip-shaped connection areas are created 21, 22, each with dashed lines in FIG Lines are delimited and labeled. The connection areas can be welding or gluing points.

Figure 3 also illustrates one on the strip 12 provided cover section 23. This extends from a bending line 24 adjacent to the ends 9 to one free edge 25 of the strip 12. The distance between the Bending line 24 and edge 25 is greater than the length of the Ends 9. Thus, the cover section 23 is closed State of the needle pocket 2, as illustrated in Figure 1 the pocket section 15 and is there, for example attached to an adhesive label 26. This sticks with a section on the lid section 23 and with another section on the pocket section 15. Between the two sections a line of perforations 27 may be provided which specifies a tear line for severing the adhesive label 26.

The strip 12 can also be understood as two in Area of the bending line 16 in one piece or otherwise connected strips 12a, 12b, the strip 12a the lid portion 23 and the central section 14 corresponds and the strip 12b corresponds to the pocket section 15.

The adhesive label is for example only as a closure educated. His glue or adhesive can do so be weak that it won't tear through the pocket section 15 can be released to open the needle pocket 2. However, it preferably also serves as a tamper-evident seal. For this purpose, its adhesive or adhesive is designed so that the adhesive label 26 is not non-destructive the pocket section 15 can be released. Then it will be at the Perforation line 27 torn to the needle pocket 2 too to open.

The needle pocket 2 described so far serves as follows for packaging knitting machine needles 5:

These are used to package the knitting machine needles 5 first grouped together in a needle handle 6 and then mechanically onto a strip 12 from the desired packaging material, such as paper applied. The strip 12 can be part of a rear the edge 25 connecting very long or endless bands or strip. However, it can already be on the edge 25 from this endless strip that is fed by machine will have been cut off. The needle handle 6 is now in the middle section 14 placed on the strip 12. there the individual needles 5 are approximately parallel to the long edges of the strip 12 aligned, the hooks 8 approximately of the imaginary bending line 16. On both sides of the needle handle is approximately the same distance from each other long edge of the rectangular strip 12 is present.

For example, it is now on both sides of the shafts 7 of the needle handle 6, an adhesive is applied to the strip 12. The adhesive can be, for example, a hot melt adhesive (Hot melt adhesive), which is viscous due to heat becomes. The pocket section 15 then becomes 180 ° hit back so that it affects the stems 7 and the Areas of the middle section present on both sides of the shafts 14 sets. By suitable pressure means, for example Rubber rollers, the pocket section 15 with the Middle section 14 are connected, the resulting Bag is just as wide as permitted by the needle handle 6. As a result, the needle handle 6 is firmly in the emerging Kept inside, i.e. the bag is just so big that it tightly spans the needle handle 6 and that it is secure is held.

The lid section is now used to close the bag 23 turned over and attached the adhesive label 26. The Knitting machine needles 5 are thus packed. The closed one The needle pocket 2 can be placed in the box 3 according to FIG. 1 be inserted.

In deviation from the above-described method, the Adhesive or adhesive for fastening the pocket section 15 on the central section 14 also on the pocket section 15 be attached. Another variation arises if for example PE-coated paper or a plastic film is used as packaging material. This is possible, for example from Figures 6 and 7. The stripe 12 is here on the side facing the knitting machine needles 5 provided with a thin layer of polyethylene 28 covering the entire Occupies surface of the strip 12. In the connection areas 21, 22 are the middle section 14 and the pocket section 15 for example by pressure and / or heat and / or welded to one another by ultrasound. The polyethylene layer 28 thus forms the connecting means to form the bag 18. It is advantageous that Needle handles of any width can be packed without that consideration when applying any glue should be taken.

A further modification of the invention results from Figure 4. Here are the connection areas 21, 22 by crimping made by a series of short cuts in the material of the strip 12 is introduced. The incisions enforce both the pocket section 15 and the Middle section 14 in the connecting areas 21, 22 and thus free short bridges that are in the flat lying other part of the strip 12 are pressed. In the connecting regions 21, 22 are the pocket section 15 and the central section 14 is thus mechanically hooked together. In this embodiment, the connection in the Connection areas 21, 22 are produced without auxiliary material. An adaptation to different widths of needle handles 6 is easy by adapting the crimping device accordingly possible.

As Figure 5 illustrates, instead of the adhesive label 26 another closure can also be provided. For example, on the pocket section 15 on one or an adhesive 31, 32, 33 is applied in several places be used to attach the lid portion 23 serves.

FIG. 9 shows an alternative embodiment of the needle pocket 2 illustrates during its manufacture. The in The description given in connection with FIG. 3 applies except for the differences explained below:

The strip 12b is separated from the strip 12a, so that the needle pocket 2 does not consist of a strip 12 but is produced from two strips 12a, 12b. Instead of Bending line 16, strip 12a projects slightly beyond hook 8 and leaves a strip-shaped area free here. On this adhesive is applied so that a strip-shaped connection area 35 arises. This connects to the connection areas 21, 22 and forms a closed one with them U. The strip 12b can then from above on the connection areas 21, 22, 35 are put on and pressed down, whereby again the section illustrated in FIG. 8 Pocket 18 is created.

Another embodiment of an inventive Needle pocket 2 is illustrated in FIG. 10. The stripe 12 here has a length which is approximately the length of the strip 12a corresponds to FIG. 9. The one overhanging the hooks 8 Section is wide enough to create the connection area 35. It is not handled. The width of the Strip 12 corresponds approximately to twice the width of the Strip 12 according to FIG. 9 or 3. The bending line 16 runs here parallel to the needles of the needle handle 6 and replaces the long edge of the strip 12. So there is a pocket section 15 formed to close the needle pocket 2 on the needle handle 6 is folded, as an arrow 36 in Figure 10 indicates. Approximately at the level of the end of the hook Shafts 7 can be provided with a dividing line 37 a cut is made when the needle pocket 2 is closed. Another cut can be made on a dividing line 38, which extends in a straight extension of the bending line 16. It is thus created by being perpendicular to each other standing dividing lines 37, 38 free waste 39, which is removed. The pocket section 15 turns on the connection areas 21, 22, 35 by one of the aforementioned Techniques attached.

As an alternative to the embodiment according to FIG. 10, the connection area 22 can also be dispensed with by the Bending line 16 directly applied to the needle handle 6 becomes. The resulting packaging is then asymmetrical but narrower. In both cases the pocket section forms 15 one integrally connected to the first strip 12a second strip 12b.

A needle bag made of flexible material, for example Paper or plastic, for the orderly packaging of needle handles 6 consists of a strip-shaped section of the desired material, one end of which over the shafts of the Needles beaten and on the edges with the middle section is connected, on which the needle handle lies. The connection takes place flat between the folded pocket section 15 and the central section 14, the strip-shaped Narrow the needle handle on both sides of the joints and thus hold the needles tightly together. The Needle bag 2 is easy and automatically manufactured, as well Easily adaptable to different needle handles.
