Definitions

  • misalignment can cause tape telescoping during winding or an axial offset winding of the tape onto the core ("off core" winding), both of which can lead to product aesthetic issues and dispensing difficulties.
  • the use of a core presents additional material inventory scheduling and storage requirements, and results in extra shipping weight and volume for the tape roll product.
  • the cost of the core itself particularly for shorter length tape rolls, can represent a significant proportion of the product's cost.
  • the disposal of the core may present waste and environmental concerns when the supply of tape from the core has been depleted. Even if the core is formed from a material or composite that is recyclable, its use requires additional handling by the user in order to be salvaged for reuse or reprocessing.
  • a next segment of the adhesive on the tape is covered with a backing sheet which presents a non adhesive surface to the mandrel for the remainder of the innermost wrap of tape about the mandrel.
  • the winding mandrel in one embodiment, it includes a cylindrical shaft having an axis of rotation, with at least a portion of the shaft having a circumferential tape supporting segment adapted for receiving tape wound thereon.
  • the circumferential tape supporting segment has a tape engaging surface portion that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the shaft to form a tape roll, and that is sufficiently pliant to permit ready axial removal of a wound tape roll from the shaft.
  • FIG. 7 is an elevational view of a winding mandrel of the present invention, broken away laterally and with portions thereof shown in section.
  • a lower turret assembly 70 is provided with opposed chucks for engaging each end of the second winding mandrel 60 and rotatably driving the winding mandrel 60 when it has been advanced to lower winding station 53.
  • the lower turret assembly 70 also has five positions or stations defined for movement of the winding mandrel 60 therethrough, including a winding mandrel loading position A, ready position B, winding position C (lower winding station 53), transfer position D and unloading position E.
  • Lay-on rollers 170 are rotatably supported on a plurality of ears 172 which are mounted to the upper plate structure 146.
  • the lay-on rollers 170 are thus also pivotally mounted about pivot axis 148 relative to the central frame bar 86.
  • the lay-on rollers 170 are axially aligned laterally across the travel path of the advancing web material 26, and arranged to define a roller nip with idler back-up roller 32 for deposition of the liner/tab segment 123 on the advancing web material 26 (see FIG. 5b).
  • the liner/tab segment 123 extending laterally across the web material 26 is also slit as it passes the knives 203.
  • a liner/tab strip 204 is formed (as adhered to each tape strip 50)
  • a liner/tab strip 205 is formed (as adhered to each tape strip 51) (see FIG. 13).
  • the tape strips 50 and 51 are then directed to the upper and lower turret assemblies 65 and 70. Alternate tape strips are directed to the alternative turret assemblies, as is typical in a tape slitter machine.
  • the turret assemblies are preferably articulated turret assemblies, which are of the type which is conventional in the pressure-sensitive adhesive tape manufacturing industry.
  • a suitable articulated turret assembly is thend RSA-450 turret of Jagenburg GmbH, Germany.
  • each turret assembly consists of a pair of spaced turret heads 64 and 69 (only one of which is shown in the drawings for each turret assembly) between which the winding mandrels 55 and 60 are supported and mounted for rotation, respectively.
  • each separate pair of winding mandrel chucks on a turret assembly has a separate drive motor to independently index those chucks about their positions on the turret assembly.
  • a pair of empty chucks engage the ends of the winding mandrel at position A (off of the loading ramp 206).
  • Those chucks are then advanced to position B, placing the winding mandrel in a ready position for tape winding.
  • the chucks are then further advanced to position C for engagement and winding of tape strips thereon. Once winding is nearly completed, that pair of chucks is then indexed to position D to finish the winding process for the winding mandrel therebetween.
  • the chucks are advanced to position E, where the chucks release the winding mandrel, thereby allowing it to exit its turret assembly via unloading ramp 208. While the relative positions of the winding mandrel stations about the turret assemblies 65 and 70 differ, their functional aspects are the same, moving through winding mandrel loading position A, winding mandrel ready position B, winding mandrel winding position C (the winding stations), winding mandrel transfer position D and winding mandrel unloading position E.
  • a radially compressible material layer 246 is mounted about the circumference of each sleeve 244.
  • the material layer 246 is formed from SCOTCHMATETM hook material having a pressure sensitive adhesive backing, manufactured by Minnesota ⁇ Vlining and Manufacturing Company of St. Paul, Minnesota, and identified by Part No. 70- 0704-2795-3. As illustrated in FIG. 8, such material is preferably spirally wound about and affixed to the exterior circumferential surface of sleeve 244 by its adhesive backing.
  • This SCOTCHMATETM material is defined by a base layer or fabric 247 which supports a plurality of upstanding stems 248.
  • the stems 248 are stiff enough not to flatten as the innermost wrap 72 is placed thereon, but resilient enough to slightly bend and provide an overall diameter reduction (radial compression) as the innermost wrap 72 is tightened (i.e., cinched) about the core tube 234 and then held in place by the adhesion of the further wraps of the tape strip thereabout.
  • the stems 248 bend and allow a generally uniform compression about the core tube 234, thereby defining the inner diameter for each tape roll 15.
  • the bending and compression of the stems 248 is illustrated in FIG. 12.
  • a segment 257 of stems 248 under the innermost wrap 72 of a tape roll 15 is shown bent in compression about shaft 210.
  • a section 258 of stems 248 on the same core tube 234 is shown uncompressed, where there is no tape wound thereabout.
  • Another alternative winding mandrel tension construction has compressible springs adjacent each end of the winding mandrel (within fixed end stops on the winding mandrel shaft).
  • a third fixed stop is secured to the shaft adjacent its midpoint, and thus allows the separate definition of axial compression (and torque) for each half of the winding mandrel by the two separately compressed springs.
  • a mechanically operable winding mandrel may also function in the process and apparatus of the present invention.
  • a diametrically collapsible/expandable winding mandrel or button bar will suffice, so long as it provides caliper compensation (independent rotation capability for each tape roll being wound) and means for support of the tape while wound and for permitting ready removal of a completed tape roll from the winding mandrel.
  • a tape cut-off and winding assembly that includes a pair of cooperative assemblies which pivot into engagement with the winding mandrel in its winding station.
  • the turret assembly provide relatively precise positioning of the winding mandrel in the winding station so that it is properly aligned for interaction with the tape cut-off and winding assembly.
  • the cut-off and winding assembly is defined by the upper enveloper assembly 56 and the upper lay-on roller and knife assembly 57.
  • an empty winding mandrel 60b is advanced to its ready position B .
  • the enveloper and knife assemblies extend laterally to engage the winding mandrel and tape strips wound thereon in each winding station. During winding (as illustrated in FIG. 6), the enveloper and knife assemblies are pivoted away from their respective winding mandrels to permit the indexing of empty winding mandrels about the turret assemblies specifically (from position A to position B).
  • a winding mandrel such as for winding mandrels 55a and 60a in FIG.
  • the turret assembly chucks in position C are indexed and winding mandrels 55a and 60a are moved to position D on their respective turret assemblies (as seen in FIG. 13). While the winding mandrels 55a and 60a in position D continue to rotate and wind tape strips thereon, empty winding mandrels 55b and 60b are moved from position B on each turret assembly into the winding stations (position C) for engagement with the advancing tape strips.
  • This winding mandrel advance sequence is shown in FIGS. 6 and 13. As this winding mandrel indexing occurs, the enveloper and knife assemblies are pivoted toward each empty winding mandrel in its winding station. This pivoting is begun as a function of the amount of web material 26 that has been advanced, as monitored by the length encoder 202.
  • the enveloper assemblies are shown to have advanced sufficiently to engage the tape strips advancing from the anvil roller 48 to the winding tape rolls on winding mandrels 55a and 60a, and the knife assemblies are ready to envelop the winding mandrel and advancing tape strips when the presence of a liner/tab strip on the advancing tape strips is detected.
  • This is accomplished by means of optical sensors, such as sensors 288 and 290 mounted on the enveloper assemblies 56 and 61, respectively.
  • the upper enveloper and knife assemblies 56 and 57 are pivoted together to fully envelope the empty winding mandrel 55b and adjacent portions of advancing strips 50.
  • the sensor 290 operates in a similar manner to detect a leading edge of the liner/tab strip 205 for triggering the final pivoting together of the lower enveloper and knife assemblies 61 and 62.
  • a tail-winder assembly 308 is also carried upon the enveloper assembly 56.
  • the tail-winder assembly 308 includes an arm 310 pivotally mounted to the enveloper frame 264 at pivot axis 312.
  • An upper end of arm 310 is pivotally connected to a linear actuator 314, such as a pneumatic cylinder which is pivotally mounter at its cylinder end to a support 316 fixed to the enveloper frame 264.
  • An extensible rod 318 of the actuator 314 is extended and pivotally coupled to an upper end of the arm 310 of the tail- winder assembly 308.
  • the arm 310 has a laterally extending anchor plate 320 which is adapted to engage the tape strips 50.
  • Lay-down rollers 322 are also pivotally mounted to the arm 310 adjacent its lower end, by a plurality of supports 324.
  • the enveloper and knife assemblies 56 and 57 are pivoted together about the empty winding mandrel 55b, as illustrated in the sequence of FIGS. 14a-14e.
  • the enveloper assembly 56 and knife assembly 57 are shown approaching the empty winding mandrel 55b, which momentarily contacts the advancing tape strip 50.
  • the enveloper assembly 56 is shown contacting the rotating empty winding mandrel 55b, with its lay-down roller 322 (which is release coated) engaging the advancing tape strip 50 to push it away from the winding mandrel 55b.
  • the springs 336 and 344 exert pressure against the first lay-on idler roller 326 and tape pinning bar 342, respectively. This secures a segment 352 of the tape strip 50 therebetween for cutting.
  • the tape strip segment 352 (bearing a leading part of the liner/tab segment 204 thereon) is held in tension as the tape knife blade 338 engages it.
  • the tape knife blade 338 has severed the segment 352 of the tape strip 50.
  • the springs 336 are in compression, urging the first lay-on idler rollers 326 against the winding mandrel 55b.
  • the springs 344 are also in compression, urging the tape pinning bar 342 against the anchor plate 320.
  • the tape strip 50 is now defined as two tape strips 50a and 50b (FIG. 14e), where tape strip 50a is almost fully wound about winding mandrel 55a, and tape strip 50b is just beginning to be wound about winding mandrel 55b.
  • the first winding mandrel 55a continues to rotate, thereby placing the tape strip 50a between the tape roll 15 and the enveloper and knife assemblies 56 and 57 in tension.
  • the winding mandrel 55a in FIGS. 14a-14k is in position D on the upper turret assembly 65, and while the winding mandrel shaft 210 of the winding mandrel 55a in this position continues to rotate, the core tube 234 about which the tape roll 15 is wound slips rotatably on the shaft 210 of the winding mandrel 55a to hold the tape roll 15 in the position illustrated by Figures 14c-14h.
  • the first lay-on idler rollers 326 are driven at a rate faster than line speed and faster than the rate of rotation of the winding mandrel 55b. This tends to direct the leading end 71 away from the driven lay-on rollers 326 and up toward the travel path defined by the strand feed guide 300 about the rotating winding mandrel 55b.
  • the strand feed and cinch rollers 292 and 294 are driven to rotate at a much faster circumferential speed than the line speed and rate of rotation of winding mandrel 55b.
  • the winding mandrel 55a continues to rotate, and because the tape strip 50a is no longer held to the enveloper assembly 56, the remainder of tape strip 50a starts winding onto tape roll 15 on winding mandrel 55a and pulling arm 310 toward winding mandrel 55a.
  • the rotational slippage of core tube 234 under the tape roll 15 on winding mandrel 55a slows as the tape roll 15 on the winding mandrel 55a again begins to rotate with the winding mandrel 55a.
  • the angular orientation of the anchor plate 320 and remaining strand of tape strip 50a causes the adhesive side 27 of the tape strip 50 to peel off of the anchor plate 320, as illustrated in FIG. 14j.
  • the sequence of events illustrated in FIGS. 14a-141 happens quite quickly.
  • the advance of the tape strip 50 is not stopped to perform the cutting and initial winding operations illustrated in FIGS. 14a-141.
  • the advance of the tape strip 50 is slowed to a speed lower than its winding speed, but it is not necessary to completely stop and then restart the tape strip advance.
  • the processor controls the motor for advancing the web material through the apparatus, the motors for the turret assemblies, the motors for rotating the winding mandrels and the motors on the enveloper assemblies.
  • the processor controls the motor for advancing the web material through the apparatus, the motors for the turret assemblies, the motors for rotating the winding mandrels and the motors on the enveloper assemblies.
  • further sensors may be provided as is typical to control the operation and coordination of such assemblies in a system of this type and complexity.
  • the winding mandrel is rotated at a 5-10% faster rate than the web material advance speed.
  • the winding mandrel rotation rate during winding varies depending upon the outer diameter of the tape roll wound on the winding mandrel, as controlled by the processor, in order to slightly exceed the web speed. That diameter is dependent upon the thickness of the web material and the tension placed thereon during winding.
  • Initial web tension (at the start of the winding sequence for a tape roll) is 2/3 to 3/4 lb/lineal inch width, and the tape rolls are wound in a constant torque mode on the winding mandrel.
  • the length of the liner/tab may be extended so that the segment thereof which previously formed the tape tab portion is long enough to extend about the entire outermost wrap of the finished tape roll, thereby masking exposed adhesive thereon.
  • Pressure sensitive adhesive tape wound with its adhesive side out requires no liner on the innermost wrap to prevent adhesive from engaging the winding mandrel, since the non-adhesive side of the tape faces the winding mandrel.
  • no liner be provided for the innermost wrap, in which instance the adhesion by wrapping about the winding mandrel would begin with the second wrap.
  • the liner/tab may be severed at its trailing lateral edge by the cut-off and winding assembly and serve only to mask the outermost wrap of a finished tape roll, rather than as a liner for an innermost wrap.

Abstract

L'invention concerne un procédé et un appareil (20) pour former des rouleaux (15) de ruban auto-adhésif, sans tube. L'appareil comprend un mandrin (55) qui porte un segment circonférentiel (234) conçu spécialement pour supporter le ruban adhésif enroulé. Ce segment circonférentiel (234) présente une portion (246) de surface en contact avec le ruban qui peut être comprimée radialement, en étant suffisamment rigide pour supporter le ruban lorsqu'il est enroulé progressivement autour du mandrin (55) jusqu'à former un rouleau (15) de ruban, et suffisamment flexible pour permettre de retirer aisément du mandrin (55) le rouleau (15) de ruban enroulé, par un mouvement axial. La première spire (72) du ruban auto-adhésif enroulée sur le mandrin (55) est masquée par une pièce adhésive (73). Cette pièce (73) constitue une partie d'un élément (123) qui a été appliqué sur le ruban lors d'une opération précédente et sectionné avant l'enroulement, l'autre partie (76) de cet élément formant un onglet terminal disposé à l'extrémité externe (75) du ruban enroulé en un rouleau (15) sans tube formé précédemment. Le segment circonférentiel (234), supportant le ruban, du mandrin (55) est porté par un arbre rotatif (210) et sa portion (246) de surface peut comporter une pluralité de tiges flexibles (248) s'étendant vers l'extérieur par rapport à l'arbre (210) et ayant à peu près la même hauteur. Le segment circonférentiel (234) de support du ruban peut, en outre, posséder une section tubulaire (244) portant la portion (246) de surface en contact avec le ruban, conçue de manière à pouvoir tourner autour de l'arbre (210).
