Definitions
- the present invention relates to a method or process for manufacturing rolls of normally tacky and pressuresensitive adhesive tape wherein the tape is wound upon itself to form an annular roll with the adhesive side of the tape facing inwardly toward the axis of the roll and to the resulting tape roll and more particularly to a pro cess wherein a multiplicity of relatively narrow tapes are slit from a much wider adhesive sheet and individually wound in the form of rolls in this manner.
- these tape rolls have been manufactured by winding the slit tapes upon a series of hollow, cylindrical or annular cores which are positioned on a winding mandrel in a specific spaced relation from one another.
- These cores have been made of cardboard. plastic and even metal. However. they normally are cut from a hollow cardboard tube into narrower cores of the desired axial dimension. in fact. this latter method has proven most useful because adhesive tapes are manufactured in different widths and each core should have substantially the same axial dimension or width as the tape wound thereon.
- the cardboard cores are cut or slit in advance of the time they are needed to manufacture tape rolls and kept in inventories of various core sizes. i.c.. widths and diameters.
- Tape rolls also are manufactured in different corc diameters for different uses, principally to facilitate dispensing of the tape from the roll. This means that the cost of maintaining and storing these core inventories must be added to the various core manufacturing costs.
- the core if there is one. is formed as the tape is wound in the process of this invention.
- a flexible and nontacky liner sheet is attached to the leading end of the tacky pressure-sensitive sheet, and the liner and the tape are wound around the mandrel in such a way that the liner envclops the periphery of thc mandrel and the tape envclops the liner prior to winding the remainder ofthe adhesive tape around the mandrel.
- the adhesive tape is wound around the liner with its tacky surface in contact with the periphery of the liner so that it holds the liner in position on the mandrel and. with the liner. forms a central cylinder about which the tape is wound around the mandrel.
- the liner is attached to the wide pressure-sensitive adhesive sheet before the adhesive sheet is slit into narrower tapes. and the liner is slit into tapes along with the adhesive sheet prior to advancing the liner and the tapes into engagement with the winding mandrel.
- the liner for any particular tape slit is in exact width-wise alignment with that tape prior to reaching the mandrel. Of course. this tape then will remain in alignment with the wound liner during forma tion of the roll. In the preferred form of this invention.
- the liner sheet is adhered to the adhesive side of the leading end of the pressuresensitivc adhesive sheet in such a way that the extreme leading end of the adhesive sheet overlaps the leading end of the liner. [t is this leading end of the adhesive sheet which is available to adhere the liner to the mandrel for each of the tapes slit from the sheets. In our preferred process using the rotating turrets described above.
- the liner sheet corresponding in width with the original adhesive sheet is applied to the under side of the adhesive sheet in timed relation with the desired length of the adhesive sheet or tape which is to be wound into rolls in such a way that the liner will appear at the winding turret adjacent the empty mandrel just as this mandrel is brought into contact with the tape.
- the tape is cut to release the rolls wound upon the full mandrel and separate them from the new leading tape ends which already are adhering the new liners to the empty mandrel. or more properly to the empty mandrels since two mandrels are used as described above. Then.
- the trailing ends of the tapes attached to the full rolls are wound about the full mandrel to complete these rolls and the new rolls are begun on the empty mandrels. first by winding the newly adhered liners about the mandrel surface and then by winding the tape, itself, about the liners.
- the liner and the tapes are wound on expandable mandrels. These mandrels are in their diametrically expanded position when the liners are attached thereto and the tape is wound about the liner to form the rolls.
- the mandrels are contracted diametrically to provide an annular space between the liner and the circumference of the mandrel. This allows the tape roll and the mandrel to be rotated with respect to one another oppositely to the direction in which the roll was wound to detach the tape from the mandrel and draw it underneath the leading end of the liner and into adhering contact therewith. This clearly releases the tape roll from engagement with the mandrel and exposes only the nonadhcsivc side of the leading end of the tape to the hollow inner circumference of the roll which is otherwise covered by the liner.
- the liner performs the first function of the prior art tape cores. that of shielding the tacky inner circumference of the hollow tape roll, first from the mandrel during manufacture principally so that the rolls can he removed therefrom, and secondly from dirt and handling during use.
- the liner. with the first convolution of tape wOLll'ld around the liner and adhered thereto acts as the central cylinder about which the tape is wound and fixes the inner diameter of the tape roll.
- This central cylinder may be quite flexible or fairly rigid depending upon the nature of the liner material which is employed.
- the liner may be a paper as thin or thinner than the tape backing, in which case its principal function is to act as a shield as described above.
- the other hand may be a paper as thin or thinner than the tape backing, in which case its principal function is to act as a shield as described above.
- the liner may be in the form of a flexible corrugated cardboard laminate of the general type described in US. Pat. No. 2,350,369 so that the central cylinder formed with the first encircling layer of tape possesses considerable rigidity and will retain its shape until that first layer or. in the direction of unwinding, the last convolution of the adhesive tape is removed or unwound from around the liner.
- the liner merely is a shield or imparts considerable rigidity to the tape roll, when that convolution of tape in contact with the liner is unwound, the liner itself also is unwound and returned to sheet form.
- the product of our invention i.e., the pressuresensitive adhesive tape roll wound around the liner
- the product of our invention has a decided functional advantage when used in any kind of dispensing equipment which normally would require removal of spent cores when the tape which they carry is all used or unwound therefrom. Since, in the tape roll of this invention, the liner is retained in its cylindrical configuration only by adhesive contact with the tape wound around it, when that tape is unwound the liner also is unwound and therefore may be removed quickly from the axle or winding shaft of the dispensing equipment in which it is mounted.
- FIG. I is a schematic view partly in section and partly in elevation of apparatus for performing the method of this invention, with the apparatus ready to wind the liner material and the tape into rolls.
- FIG. 2 is a view similar to FIG. I of the tape winding end of the equipment showing the apparatus in the position it would assume when full tape rolls have been wound on the mandrels and the next length of liner material approaches the winding position.
- FIG. 3 is a view similar to FIG. 2 of the same equipment. showing the apparatus just after the turrets supporting the mandrels have been rotated 180 to cause the full mandrels and the empty mandrels to exchange positions and the empty mandrel to enter into engagement with the leading end of the tape overlapping the liners.
- FIG. 4 is a view similar to FIG. 3 showing the apparatus just after the trailing end of the tape attached to the full mandrels have been cut and wound thereon and with the liners in position on the empty mandrcls ready for winding into new tape rolls.
- FIG. 5 is a portion of a view taken along the line 55 of FIG. I, partly in section and partly in elevation showing how adjacent tapes cut from the same sheet are alternately wound on separate mandrels.
- FIG. 6 is a somewhat enlarged view, partly in section and partly in elevation taken along the line 6-6 of FIG. I with the liner material adhered to the under side of the pressure-sensitive adhesive supply sheet.
- FIG. 7 is a more greatly enlarged schematic view. partly in section and partly in elevation. of one of the tape winding mandrels in its expanded condition showing how a liner attached to the under side of the tape 5 to be wound on the mandrel is secured to the mandrel for winding purposes through the adhesive under side of the extreme leading edge of the tape which overlaps the liner.
- FIG. 7A is an even more greatly enlarged view of the It) encircled portion of FIG. 7, partly in section and partly in elevation, showing the attachment of the liner to the mandrel through the overlapping tape as the mandrel begins to rotate to wind the liner around it.
- FIG. 8 is a view similar to FIG. 7 of the same mandrel l5 just after the liner has been wound there-around.
- FIG. 8A is a view similar to FIG. 7A of the encircled portion of FIG. 8 showing the relationship of the tape and the liner at the point where the ends of the liner overlap just after the liner has been wound around the 30 mandrel and the tape is about to be wound into a roll around the liner.
- FIG. 10 is a view similar to FIG. 8 but showing the tape roll fully wound on the mandrel with the mandrel in its collapsed condition and the extreme leading end of the tape which was adhered to the mandrel bent around and under the corresponding leading end of the liner so that its nonadhesive surface faces inwardly toward the mandrel.
- FIG. 9A is a more greatly enlarged view of the encircled portion of FIG. 10 showing the position of the tape and the liner just as the tape roll and the mandrel have begun to be rotated with respect to one another oppositely to the direction in which the roll was wound to draw the leading tape end under the liner and detach it from the mandrel.
- FIG. "IA is a view similar to FIG. 9A after the tape end has been fully released from the mandrel and is bent around and under the corresponding leading end of the liner as shown in FIG. I0.
- FIG. II is a view similar to FIG. 8A showing a slight modification wherein the liner sheet is somewhat shorter so that its ends do not overlap one another but come into close proximity.
- length refers to the dimension in the direction of travel of the sheets and width refers to their dimension at right angles to length and transverse to travel or in an axial direction with reference to the supply rolls.
- the pressure-sensitive adhesive sheet 32 comprises a backing layer or sheet 35 which presents an adhesive layer 36 on one major surface and is nonadhesive or nontacky on its other major surface.
- the supply roll 3] is wound with the adhesive side of the sheet facing inwardly toward the axis of the roll and the nonadhcsivc surface of the sheet facing outwardly.
- the pressure-sensitive adhesive sheet 32 is drawn under and around spaced idling and positioning rollers 37, which contact the nonadhcsive top side of the sheet. by a driven pull roll 38 which contacts the adhesive underside of the sheet.
- the liner material 34 is drawn from its supply roll 33 and fed in the same direction as the pressure-sensitive adhesive sheet by a pair of intermittently driven feed rollers 39.
- the feed rollers 39 draw the material around a guide roller 41 and then through the nip between them to feed the desired length of liner material 34 between a pair of spaced horizontal guides 41 into position over a horizontal support. such as a vacuum box lift table 42.
- One end of the table 42 is adapted to act as an anvil 43 for cooperating with a cutting knife 44 positioned above the liner for cooperative vertical movement with respect to the anvil 43 to sever the desired length from the liner sheet.
- the lift table 42 is raised to press the liner 34 into adhesive contact with the underside of the pressure-sensitive adhesive sheet 32 passing between the positioning rollers 37, shown by the dotted lines in FIG. I and also in FIG. 6. The feeding of the liner sheet 34.
- the adhesive sheet 32 with the liner 34 attached to its adhesive underside is drawn around the pull roll 38 as described hereinbefore, and then underneath a driven platen or anvil roll 43.
- a bank of circular cutting knives 44 is positioned directly under the platen roll 43 in such a way that the knives can be adjusted towards and away from the roll for slitting the pressure-sensitive adhesive sheet and the liner into narrow widths of pressure-sensitive adhesive tape 45.
- the sheet will be slit into I tapes all of which then pass around the platen roll 43 and an idler roller 46 adjacent thereto with their non-adhesive surface facing the platen roll 43 and their adhesive surface facing the idler roller 46. Then. as shown most clearly in FIGS. I and 5, adjacent tapes 45 slit from the same sheet 32 are wound alternately on separate mandrels 47 so that there are 60 tapes on each mandrel. and each of the mandrels is rotatably mounted in a separate winding turret 48.
- the turrets 48 which are identical. are mounted one above the other and controlled so as to operate simultaneously in the same timed relation with respect to the tape being wound.
- Each of the turrets 48 is of the type which is conventional in the pressure-sensitive adhesive tape manufacturing industry and comprises a pair of spaced cylindrical heads 49 (only one of which is shown in the drawings) between which the mandrels 47 are supported and mounted for rotation. conventionally. the heads 49 at one end of the turrets contain the drive for indexing the turrets. i.e.. rotating them l8() to transpose the positions of the two mandrels 47, and for engaging and rotating the mandrels 47 once they are in the desired positions. (The driving ends of the turrets are not specifically shown in the drawings). Typically. the turrets may be rotated by a spur and ring gear combination and the mandrels may be driven through a planetary gear train mounted in the driving head of the turrets.
- the driven end of the mandrel is geared to enter into driving engagement with the planetary gear train when the mandrels are positioned in the driving heads of the turrets 48.
- cutting and lifting the liner material 34, the indexing of the turrets 48, the rotation of the mandrels 47 and the feeding of the adhesive sheet and tapes with the liners attached. all are controlled in timed relation by cams and other means conventionally used for this purpose to perform the process steps which will be described hereinafter.
- each of the turrets presents retractable air actuated sockets 51 for engaging the opposite end of each of the mandrels 47 after the driving end of the mandrel has been positioned in the driving head at the opposite end of the turret.
- These air driven sockets 51 may be extended to engage the mandrel 47 and retracted to allow the mandrel to be removed from the turret simply by actuating a pneumatic cylinder 52 which controls the sockets.
- the mandrcls 47 themselves, are conventional expandable mandrels which are pneumatically actuated by air supplied through the end of the mandrel through a passageway 53 in the air actuated socket 51, as shown in FIG. 5.
- the mandrel 47 may be either expanded or collapsed through control of this air supply.
- FIG. 2 shows the winding apparatus of FIG. 1 just as the tape rolls on the top or winding mandrel have been fully wound and the next liners are moved into position adjacent the wound mandrels.
- the pull roll 38 and the platen roll 43 are stopped and locked in position, the winding mandrels 47 are disengaged from their drive. and the turrets 48 are rotated l80 to transpose. or exchange. the top and bottom mandrels in each turret. As the turrets 48 are rotated in this manner.
- the tape roll 50 on the top mandrel unwinds just enough to allow the mandrels to exchange positions as the empty bottom mandrel swings up into contact with the liner 34 and finally assumes its winding position above the full mandrel. as shown in FIG. 3.
- a transverse cutting bracket 55 is mounted at the ends ofa pair of swinging arms 56 which are pivotally mounted for rotation about the centerline of each of the turrets 48. Normally, the bracket 55 rests against the leading side of the empty mandrel 47 at the bottom of the turret. as shown in FIG. 2, and when the turret is rotated to exchange the mandrels. the bracket 55 is rotated with the turret in such a way that it enters into adhering contact with the underside of the adhesive tape just ahead of the empty mandrel as shown in FIG. 3.
- FIG. 7 shows a winding mandrel 47 in its expanded condition just as the extreme leading end M of a length of adhesive tape 45 to which a liner 34 is attached is brought into adhering engagement with the surface of the mandrel.
- the mandrel is rotated counterclockwise. as shown in FIG. 7A, to begin to wind the liner 34 around and in circumferential contact with the outer cylindrical surface of the mandrel.
- the length of the liner 34 is slightly greater than the circumference of the mandrel 47 so that the ends of the liner overlap one another slightly when the liner is wound completely around the mandrel.
- the adhesive tape 45 is wound spirally around the mandrel upon itself in successive overlapping convolutions to form a hollow annular cylinder or roll with the adhesive surface of the tape facing inwardly toward the axis of the roll.
- the liner sheet 34 is adhered to the adhesive surface of the innermost convolution 62 of the tape 45 in such a way that it completely covers the adhesive surface thereof and thereby prevents this surface from adhering to the hand or any other object placed inside the hollow of the roll.
- the mandrel 47 In order to disengage the liner 34 from the mandrel 47 and make it possible to remove the newly wound tape roll 50 therefrom. it is necessary to release the tape or detach it from the mandrel. To accomplish this. the mandrel 47 first is collapsed as shown in FIGS. 9A. I and A. and then the mandrel 47 and the tape roll 50 are rotated with respect to one another in a direction opposite to that in which the tape roll 50 is wound. as indicated by the arrow in FIG. 9A, to detach the tape from the mandrel 47 and bend the leading end 61 around and under the corresponding leading end of the liner 34 as shown most clearly in FIG. 10A. In this configuration, only the nonadhesivc back surface of the extreme leading end 61 of the tape faces inwardly toward the hollow of the roll. As a result. the whole hollow inner surface of the tape roll is effectively shielded against adhesive contact.
- FIG. ll illustrates a slight modification of the embodiment of the foregoing figures wherein the liner 34 is slightly shorter than the circumference of the expanded mandrel with the result that the ends of the liner do not overlap and fall just short of abutting relation on the mandrel. While this modification eliminates the slight bump caused by the overlapping liner material. it does not form quite as rigid a structure as that of the foregoing embodiment.
- of the tape is disengaged from the mandrel 47 and bent around and underneath the corresponding leading end of the liner 34 after the mandrel has been collapsed as described in connection with FIGS. 9A and IIIA.
- the liner 34 only is secured in position in the finished tape roll by virtue of its adhesion to the tape with which it is wound and more specifically only through adherence to the innermost convolution 62 of the tape wound around the liner.
- the liner 34 automatically is released and unwound at the same time that the tape is unwound.
- the liner material may be fed sideways instead of endwise over the air table 42 with a side instead of an end cutoff device to sever the desired length of liner from its supply.
- the liner could be precut and placed in a stack underneath the pressure-sensitive adhesive sheet and sequentially fed upwardly in timed relation with the adhesive sheet to attach the liners in their proper positions as described hereinbefore.
- a roll of normally tacky and pressure-sensitive adhesive tape said tape having one of its major surfaces tacky and adhesive and being wound spirally upon itselt in successive axially aligned overlapping convolutions with its adhesive surface facing inwardly toward the axis of the roll to form a hollow annular cylinder, and a liner sheet adhering to the adhesive surface of the innermost convolution of said tape in overlapping relation therewith and having a nonadhesivc surface facing the hollow of said roll. said liner being long enough to effectively cover the inwardly facing adhesive surface of the said innermost convolution of said tape and being unattached to itself except through adherence tc the said innermost convolution. whereby said liner is unwound with said tape as the innermost convolution of the tape is unwound from said roll.
- a roll of pressure-sensitive adhesive tape according to claim I, wherein the outwardly facing surface 01 said tape is nonadhesivc and the innermost leading end of said tape is bent around and under the corresponding leading end of said lincr. whereby the nonadhesivc surface of said innermost tape end is facing inwardly toward the hollow of said roll.
