Definitions

  • the present invention concerns an apparatus and a method for splicing webs of indeterminate length. More particularly, the invention concerns such apparatus and method in which the tail end of a preceding or old length of web and the lead end of a following or new length of web are trimmed, the trimmed ends are abutted and then are joined by applying a strip of adhesive tape to complete the splice.
  • U.S. Patent 3,245,861 discloses a web splicer for use in label printing equipment in which the lead end of the following or new length of web is manually trimmed and a length of tape is applied across the trimmed end. The preceding or old length of web is then stopped as its source spool is emptied and its tail end is trimmed. The new lead end and applied strip of tape are then pressed against the old tail end to form an overlapping joint. Such overlapping joints are acceptable in many industrial applications but present problems during subsequent handling of the web in other applications.
  • U.S. Patent 3,939,032 discloses a web butt splicer in which the new lead end is trimmed manually and a length of tape is applied across the lead end.
  • U.S. Application B339,446 shows a web cutting and splicing apparatus in which a hot wire is used to cut two webs and heat their ends sufficiently to facilitate formation of a fused butt joint.
  • U.S.Patent 4,204,898 shows a tape winding and splicing apparatus in which side by side input platens hold tape and leader webs and an opposed, coplanar process platen holds the tail end of the tape or leader most previously cut. In use, a leader running between two reels is cut in an initial position of the input platens in which the leader's input platen is aligned with the process platen.
  • U.S. Patent 4,501,630 discloses an apparatus for splicing a leader to magnetic tape in which the leader and tape are fed along parallel, coplanar guide grooves in a receiving table which is movable transversely to permit either the leader or the tape to move into a coplanar guide groove on an adjacent receiving table. After the lead end of the tape and the tail end of the leader have been trimmed in separate operations, the two ends are abutted and a strip of tape is applied.
  • U.S. Patent 4,629,531 shows an apparatus for joining sheet ends such as might be used in a newspaper printing plant. The new web is stopped and trimmed manually, after which glue is applied to its lead end.
  • U.S. Patent 4,801,342 discloses a method and an apparatus for forming a butt splice in which the old web and the new web are run along opposite sides of a planar cutting anvil along whose edge cutting wheels are run to trim the lead and tail ends, after which a strip of tape is rolled over the abutted ends.
  • Splicers of the types shown in these patents typically require intervention by the operator for steps such as trimming the lead or tail ends or applying tape strips to applicator wheels or to the trimmed ends. While this type of operator involvement is acceptable in many applications, certain high speed web handling operations, such as the spooling of photographic film, are slowed undesirably. Particularly when the web handling must take place in the dark, as in photographic applications, the operator's involvement can significantly slow the process.
  • U.S. Patent 4,328,066 shows a tape splicer in which the tape is pulled onto a rotating vacuum drum which is translated into contact with the abutted ends to complete the splice, after which the vacuum drum is withdrawn to a position where the next strip can be cut. A separate roller is used to smooth out the splice.
  • U.S. Patents 4,475,970 and 4,478,674 show tape splicers in which the tape is cut to lengths on a square block and then press applied to the abutted ends.
  • Patent 4,533,586 shows an apparatus for applying labels to packages in which a perforated strip of labels is moved past a rotary cutter which cuts the strip into individual labels and passes them to a transfer drum which places the labels on a heated vacuum applicator drum which presses the labels onto the packages.
  • U.S. Patent 4,848,691 shows a splicer in which the new web is trimmed, a strip of tape is applied to its trimmed end and then the trimmed end and tape are pressed into a lap joint with the still moving old web.
  • tape dispensers also have been used extensively.
  • One type manufactured by the 3M Company, uses knurled disks to move the tape through the dispenser. The operator depresses a ratcheting crank which turns the knurled disks to meter the tape, after which the operator must cut the tape against an adjacent serrated blade.
  • Another type of dispenser also made by the 3M Company, meters and cuts the tape by means of a metering wheel whose periphery comprises a series of raised ribs which contact the sticky side of the tape. Between these ribs are recesses large enough to permit the operator to insert a finger to peel away a cut strip after a plunge type knife has severed the tape near the preceding rib.
  • Dispensers of these general types are shown in German Patent 963,128.
  • the free end of a tape is pushed through the throat of a guillotine type cutter, which can lead to stubbing of the tape and improper operation of the dispenser.
  • Other types of tape applicators are described in an article by Walter C. Larsen entitled “A study in machine development” , Modern Packaging , Volume 33, No. 7, March 1960, pages 201 and forward.
  • Vacuum drums again are used to carry strips of tape, sticky side out, to transfer drums or directly to the place of application of the strips.
  • the primary objective of this invention is to provide a method and apparatus for splicing webs of material in which operator interaction would be limited to replacement of the sources of web and splicing tape as they are consumed.
  • a further objective of this invention is to provide such a method and apparatus which automatically trims the ends of the old and new webs and abuts them for application of a strip of splicing tape.
  • Another objective of this invention is to provide such a method and appartus which will automatically complete the splice in a matter of seconds without intervention by the operator.
  • Yet another objective of this invention is to provide such a method and apparatus which will ensure proper registration of edge perforations between new and old webs.
  • Still another objective of this invention is to provide such an apparatus which is modular and can be relatively simply installed in place of existing splicing equipment.
  • Still another objective of this invention is to provide such an apparatus and method which can splice with single or double sided tape with little sensitivity to the degree of stickiness of the tape, the flexibility of the tape support or the tendency of the support to curl.
  • an apparatus for trimming the tail end of a first length of web and the lead end of a second length of web and then placing such trimmed ends in abutment.
  • a first input platen is provided for supporting the first length of web and a second input platen is provided for supporting the second length of web.
  • the two platens have trailing edges which are parallel.
  • Means are provided for selectively stopping movement of the first length of web across the input platen and for cutting the first and second lengths of web at the trailing edges of the platens.
  • a process platen is positioned opposite the trailing edges; and means are provided for relatively moving the platens between a first position in which the process platen receives the first length of web from the first platen and a second position in which the process platen receives the second length of web from the second platen.
  • a trimmed end of web on one of the input platens may be abutted with a trimmed tail end of web on the process platen.
  • the platens have perforated bed plates to facilitate application of vacuum to hold the webs during cutting or the passage of air to support the webs during movement.
  • means are provided for registering the perforations of webs on the input platens with those of the web on the process platen. To ensure such registration, the webs are trimmed by a pair of blades which essentially simultaneously engage the webs at the trailing edges of the input platens.
  • the previously described apparatus for trimming and abutting preferably is combined with the apparatus for cutting and applying strips of tape which comprises a first rotable drum means for drawing a web of tape from a suitable source. Means adjacent the first drum cut the tape into predetermined lengths while the web is moving on the first drum. A second rotatable drum removes the lengths of tape from the first and passes them to a third tape applicator drum. Means are provided for translating the tape applicator drum away from the second drum and rolling the applicator drum along a surface to apply the lengths of tape. When such an apparatus is combined with the structure described in the preceding paragraphs, the lengths of tape are applied across the abutted ends of the old and new webs.
  • the first and second drums each comprise a plurality of circular disks mounted for rotation, the edges of the disks being interleaved so that lengths of tape of the first drum are transferred to the second.
  • the edges of the disks of the two drums are knurled to control the degree of adhesion of the tape to the drums, the adhesion to the first drum being substantially greater than that to the second drum; and the second drum has a substantially higher peripheral velocity to facilitate transfer of the strips.
  • the applicator drum preferably is vacuum actuated and rotated with a somewhat higher peripheral velocity than the second drum, to remove the cut lengths of tape easily from the second drum. Because the tape is metered out and cut while it maintains contact with the knurled surface of the first drum and is peeled free only when needed, the usual difficulties of advancing the free end of a sticky tape are avoided.
  • the previously described method for trimming and abutting preferably is combined with a step of cutting and applying lengths of tape in accordance with the invention, the lengths of tape being cut on a first drum and then removed sequentially by a second drum and passed to a rotating vacuum drum. The vacuum drum is then translated away from the second drum and rolled along a surface to apply the lengths of tape to such surface.
  • the apparatus is seen to comprise a rugged base plate 10 positioned preferably between an old or expiring roll or source 12 of web 14 of indeterminate length, such as conventional 35 mm photographic film having edge perforations, not illustrated; and a new or waiting spare roll or source 16 of web 18 also of indeterminate length, such a photographic film.
  • Web 14 is threaded about a flanged roller 20 mounted for rotation on an axis perpendicular to base plate 10 and then over a flanged registration sprocket 22 aligned with roller 20.
  • Sprocket 22 is attached to a ratchet wheel 24 and the assembly is mounted for rotation on an axis perpendicular to base plate 10.
  • web 18 is threaded about a pair of flanged rollers 26 mounted for rotation about axes perpendicular to base plate 10 and then over a flanged registration sprocket 28 aligned with rollers 26.

  • input platens may be provided with edge guides 40,42, shown only in Figure 4 for ease of illustration. Guides 40,42 are aligned with the flanges on sprockets 22,28 to ensure that webs 14 and 18 will run straight and parallel across input platens 36,38.
  • input platens 36,38 comprise flat perforated bed plates 44 operatively connected to manifolds 46 which in turn are connected by suitable pneumatic fittings 48 to a conventional source of pressurized air or vacuum (not illustrated).

  • Carrier block 50 is provided in its rear surface with a vertically extending slot 56, as indicated in phantom lines, which slidably engages a vertically extending spline 58 provided on a flange 60 attached to a side wall of bracket 32.
  • a handle 62 is provided for manually moving carrier block 50 up and down; however, such movement typically is provided in operation by a pneumatic cylinder 64 having its head end 66 pivotably attached to base plate 10 by means of a cylinder mount 68 and its rod end 70 pivotably attached to carrier block 50 by means of a flange 72.
  • a pneumatic cylinder 64 having its head end 66 pivotably attached to base plate 10 by means of a cylinder mount 68 and its rod end 70 pivotably attached to carrier block 50 by means of a flange 72.
  • Attached to the vertical side of carrier block 50 exposed through the open end of U-shaped bracket 32 is a stiff metal plate 73 having a pair of vertically spaced, laterally extended and resilient arms 74,76 whose lower edges define a pair of cutting knives 78,80 having downwardly angled cutting edges.
  • An upper bracket 86 and a lower bracket 88 extend forwardly from base plate 10 and rigidly support between them a vertically extending slide 90, illustrated only schematically, on which a rigid carrier plate 92 is mounted for movement upward and downward as viewed in Figures 1 to 3. Movement of carrier plate 92 between the positions of Figure 1 and Figure 3 is controlled by a pneumatic cylinder 94, shown positioned behind slide 90, whose head end 96 is attached to bracket 88 and whose rod end, not illustrated, is operatively connected to carrier plate 92.

  • Trimmed end platen 102 is directly opposite to and aligned with input platen 38 in the position of Figure 3, but above input platen 38 in the position of Figures 1 and 2.
  • Each of platens 98,100,102 preferably includes a perforated bed plate similar to bed plates 44.
  • each of platens 98,100,102 preferably comprises edge guides similar to guides 40,42 which optionally may be provided or input plates 36,38.
  • manifolds 104 connect each platen 98,100,102 via suitable pneumatic fittings 106 to a conventional source of pressurized air or vacuum (not illustrated).
  • trimmed end platens 98,102 are provided at their trailing edges with pairs 108,110 of spaced locator pins for engaging the edge perforations in webs 14,18.

  • pawl 112 is shown disengaged from ratchet wheel 24, thereby permitting old web 14 to pass over input platen 38 and process platen 100; whereas, pawl 114 is shown engaged with ratchet wheel 30, thereby restraining new web 18 from movement across input platen 36 and trimmed end platen 98.
  • the old web 14 is drawn from roll 12, around flanged roller 20, around free-wheeling flanged registration sprocket 22, across input platen 38 and process platen 100, around flanged rollers 122,124,126 and on to subsequent processing equipment.

  • the arrangement of cylinder 120 and slotted pivot 116 of pawl 114 provides sufficient flexibility in the linkage to enable the inherent damping and compliance characteristics of the cylinder to stop the web without damage to its perforations.
  • registration sprockets 22 and 28 are positioned so that at trailing edges 82,84 of input platens 36,38, the edge perforations of webs 14,18 are in perfect registry when both webs are stopped.
  • Vacuum is then applied through the bed plates of platens 38,100 and 36,98 to hold webs 14,18 securely in place on their respective platens.
  • Pneumatic cylinder 64 is then actuated to cause carrier block 50 to move downward to the position shown in Figures 2 and 4. This movement causes knife blades 78,80 to pass closely over trailing edges 82,84 to cleanly cut web 14 and trim the lead end of web 18, while leaving the edge perforations on the lead end of web 18 and those on the tail end of web 14 in registry.

  • Drive wheel 174 is sized so that applicator roller 130 will have a peripheral velocity approximately ten per cent higher than that of release drum 172. Note, however, that the surface of applicator roller 130 is in close proximity to but does not contact the surface of release drum 172.
  • shaft 146 passes loosely through a carrier block return spring 176 having a fixed end 178 positioned against a stop pin 180 extending rearwardly from center plate 134, and a movable end 182 crimped over one edge of an essentially rectangular knife carrier block 184 mounted for free rotation on shaft 146.
  • carrier block 184 To the rear of carrier block 184, shaft 146 fixedly supports a ratchet wheel 186 and, further to the rear, fixedly supports a tape acquisition drum 188 comprising a plurality of axially spaced disks with knurled peripheral surfaces having the general configuration shown in Figure 14B.
  • the knurling is of the same general type as used for release drum 172, except that the ridges of the knurls are flattened, preferably having a circumferential width beta of about 0.0508 cm.
  • the sizes of drive pulley 162, drive pulley 168, release drum 172 and acquisition drum 188 are chosen so that release drum 172 has a peripheral velocity approximately fifty per cent higher than that of acquisition drum 188. As shown in Figures 6 and 13, the disks of drums 172 and 188 are interleaved, for a purpose to be discussed.
  • carrier block 184 includes on its rear side a transverse slot 190 in which a knife carrier plate 192 is slidably mounted and secured by keeper straps 194,196.
  • Knife carrier 192 includes at one end a rearwardly extending arm 198 on which a plunge knife 200, preferably pointed or arrow head shaped, is mounted.
  • Knife carrier 192 also includes at its opposite end a forwardly projecting tab 202 which extends beyond the forward face of carrier block 184 and is attached to one end of a knife carrier return spring 204, the other end of which is attached to a pin 206 extending from the forward face of carrier block 184.
  • a forwardly projecting cam follower pin 208 which cooperates with a flipper cam 210 pivotably mounted on a stub axle 212 extending rearwardly from center plate 134.
  • Flipper cam 210 comprises a flat upper flange 214 extending rearwardly and a flat front flange 216 extending downwardly.
  • a flipper cam return spring 218 is mounted on axle 212 with its fixed end 220 bearing against a stop pin 222 projecting rearwardly from center plate 134 and its movable end 224 captured in a slot 226 provided in the end of flipper cam 210 remote from axle 212. Downward movement of flipper cam 210 is limited by a stop pin 228 projecting rearwardly form center plate 134 just below slot 226.
  • pawl 230 Also attached to carrier block 184 is a knife carrier return pawl 230 having a pivot pin 232 extending rearwardly from carrier block 184. At its upper end, as best seen in Figures 9 to 13, pawl 230 includes a forwardly projecting tab 234 which extends into close proximity with the rear surface of center plate 134. A pawl return spring 236 is attached to tab 234 at one end, its other end being attached to a pin 238 projecting from one edge of carrier block 184. At a location closer to pivot pin 232, pawl 230 includes a rearwardly projecting dog 240 for engaging ratchet wheel 186.
  • Rear plate 132 includes an upwardly extending arm on which a source or spool 242 of single or double sided adhesive tape is mounted for rotation. As seen most clearly in Figures 14 to 16, a web 244 of tape of indeterminate length is led from spool 242 and passes, sticky side out, around a roller 246 mounted on a manually movable lever 248 pivoted to rear plate 132 on an axle 250. To thread web 244 into tape dispenser and applicator 130, lever 248 is depressed counterclockwise as viewed in Figure 14 until a stop roller 252 mounted on a side arm 254 of lever 248 contacts acquisition drum 188.
  • a return spring 256 is mounted on an axle 258 projecting forwardly from rear plate 132 and has its fixed end against one of spacers 138 and is movable end bearing on lever 248. With roller 246 raised from acquisition drum 188, web 244 is then passed around roller 246 as shown in Figure 15 and lever 248 is released so that spring 256 presses roller 246 against web 244 whose sticky side then engages the flat tops 260 of the knurls on acquisition drum 188. Once web 244 has been thus engaged with acquisition drum 188, handle 148 shown in Figure 7 may be indexed to rotate shaft 146 and cause drum 188 to rotate clockwise and draw more of web 244 from roll 242.
  • each rotation of shaft 146 causes four cycles of operation of these mechanisms; however, those skilled in the art will appreciate that fewer or more cycles could be provided by changing the number of teeth on ratchet wheels 150 and 186.
  • Figure 9 shows the mechanism as it appears when a cycle of operation has just finished. As shaft 146 rotates clockwise, ratchet wheel 186 engages dog 240 on pawl 230 and thus pulls carrier block 184 along.
  • cam follower pin 208 on knife carrier 192 eventually comes into contact with the upper surface of flange 214 of flipper cam 210, thus causing knife carrier 192 to begin to move toward shaft 146 and bringing plunge knife blade 200 closer and closer to the periphery of acquisition drum 188.
  • acquisition drum 188 is provided with a plurality of inwardly extending slots 189, four in the illustrated embodiment, the slots extending axially along the drum through each of its constitutent disks.
  • Plunge knife blade 200 is positioned to enter one of slots 189 as knife carrier 192 is forced toward shaft 146 by flipper cam 210.
  • Slots 189 and plunge knife blade 200 preferably are angled slightly away from a radial orientation toward the axis of shaft 146, in the direction so that slots 189 open toward the rotation of shaft 146. This arrangement ensures that if web 244 were to adhere to the knife blade as the blade is extended into the slot, the leading portion of the web would strip from the blade. Conversely, when the blade is withdrawn from the slot in the manner now to be discussed, the trailing portion of the web would strip from the blade.
  • plunge knife blade 200 When the mechanism has reached the position of Figure 11, plunge knife blade 200 has reached the position shown in Figure 16.
  • the grip of the adhesive on web 244 to flats 260 prevents the web from being drawn into slots 189 as it is being cut and results in clean, straight cuts.
  • the arrow head shape of knife blade 200 helps prevent the web from being drawn into the slots, as it significantly reduces the cutting force required.
  • a small additional rotation of shaft 146 then causes cam follower pin 208 to slide off the end of flipper cam 210, thus allowing knife carrier 192 to retract knife blade 200 from slot 189 under the influence of spring 204.
  • a small further rotation of shaft 146 causes tab 234 of pawl 230 to engage a stop pin 264 projecting rearwardly from center plate 134.
  • Pawl 230 thus is lifted so that dog 240 comes out of engagement with ratchet wheel 186. This permits carrier block 184 to rotate counterclockwise under the influence of return spring 176 until the position of Figure 9 is reached again and dog 240 has reengaged ratchet wheel under the influence of spring 236.
  • the distance along the periphery of release drum 172 from acquisition drum 188 to vacuum roller 130 must be substantially less than the desired length of the strips of tape being cut; so that, the trailing edge of each strip will still be adhered to acquisition drum 188 when its leading edge is acquired by vacuum roller 130, thus preventing the strip from peeling away prematurely.
  • the differential adhesion of the web to drums 172 and 188, along with the peripheral velocity overspeed of release drum 172, prevents tape from adhering to release drum 172 and also allows acquisition drum 188 to control the squareness and advance of each cut stip from web 244.
  • applicator roller 130 While applicator roller 130 is positioned as shown in Figures 9 to 17, a hub 266 at its rear portion engages knurled wheel 174 to drive vacuum roller 130 approximately ten per cent faster than release drum 172. See Figure 17 for the engagement of hub 266 and wheel 174. As indicated previously, applicator roller 130 is mounted for translation into and out of contact with the abutted ends of web positioned on process platen 100 and one of input platens 36,38. For this purpose, a slide 268 is attached to the rear surface of front plate 136, within which slidable carrier 160 is mounted for movement between the two positions shown in Figures 17 and 18.
  • a mounting block 270 is attached to the rear surface of carrier 160 and, in turn, supports a leaf spring mounting block 272 having parallel upper and lower surfaces from which a pair of leaf springs 274,276 extend toward release drum 172. Attached to the other ends of leaf springs 274,276 is a conventional bearing block and air fitting 278 which rotatably supports a shaft 280 for applicator roller 130. A vacuum connector 282 is attached to fitting 278 to provide the necessary vacuum for operation of applicator roller 130.
  • a flange 284 extends rearwardly from the lower rear face of slide 268 and ends just below central plate 134. As shown in Figures 7, 17 and 18, flange 284 is provided in its rear face with a cam slot 286.
  • cam slot 286 slopes downwardly from the position of Figure 17 in which hub 266 engages wheel 174 to the position of Figure 18 in which applicator roller 130 moves across the surfaces of platens 100 and 36 or 38, indicated in phantom.
  • Leaf springs 274,276 permit this movement of applicator roller 130 and, once roller 130 contacts platen 100, also provide a continuous downward bias to the roller to ensure that each strip of tape is securely applied to the abutted ends of webs 14 and 18, even if process platen 100 and one of input platens 36,38 are not positioned in precisely the same plane. And, because applicator roller 130 is covered with a compliant silicone rubber, it tends to move rather smoothly over small irregularities and misalignments.
