Definitions

  • This invention relates to an apparatus and method for cutting a travelling web of paper being wound on one spool and transferring the web to an empty spool while the web continues to travel.
  • US-A-4659029 describes an apparatus for cutting with a tape a travelling web of paper being wound on a first spool and transferring that travelling web onto an empty spool by attaching said tape to said empty spool, comprising: means for supplying a cutting tape; an elongated guideway for said cutting tape extending beneath and across the path of travel of said web, said elongated guideway having an elongated open slot facing towards said path of travel of said web and having opposite open ends adjacent the side edges of said travelling web, said guideway being adapted to receive said tape delivered slidingly into one said open end and to deliver said tape from said other open end beyond the edge of the travelling web; and adhesive applying means located adjacent said one open end of said guideway for applying an adhesive without any covering thereon to a surface of said cutting tape before said cutting tape enters said one open end of said guideway.
  • US-A-4659029 further describes a method of cutting a travelling web of paper being wound on a spool and transferring the web after cutting to an empty spool, the method including feeding a cutting tape into an elongated guideway positioned beneath and extending laterally across the web of paper, applying adhesive without any covering thereon to a portion of the cutting tape at its forward end prior to feeding the cutting tape into the guideway, recovering the tape from the far end of the guideway and introducing it into the nip between the empty spool and the roller driving that spool with the adhesive portion contacting the empty spool, to cause the tape automatically to spirally wrap around the empty spool while cutting the web of paper.
  • the present invention aims to provide further improvements in cutting apparatus and cutting methods of the kind taught in US-A-4659029.
  • the apparatus of the present invention is characterized in that the adhesive applying means are arranged to apply adhesive to a surface of the cutting tape which faces away from the slot of the guideway, and in that the guideway provides a supporting surface on which cutting tape can slide through the guideway, the supporting surface being disposed to be out of contact with the surface of the cutting tape to which adhesive is applied by the adhesive applying means whereby the cutting tape can slide through the guideway without adhesive adhering thereto.
  • the method of cutting a travelling web of paper in accordance with the present invention is characterized in that the cutting tape is slid through the guideway on a support surface with its adhesive portion facing and out of contact with the support surface.
  • a clamping means releasably grips the cutting tape after the forward end exits the far end of the guideway and selective means releases the clamping means to permit the end of the cutting tape to be caught by the nip and spiral the cutting tape about the empty roll thereby cutting and transferring the paper web.
  • FIG. 1 shows the general type of equipment employed in a paper manufacturing plant to wind-up the manufactured paper on rolls for storage and use elsewhere.
  • a continuous web of paper 20 travels at a relatively rapid rate of speed to a combination of spools upon which the paper is rolled.
  • Paper web 20 advances toward tension roll 21 mounted in journals on supports 22, leading web 20 over driving roll 23 and winding about spool 24 turning in the direction of arrow 25.
  • Driving roll 23 turns in the direction of arrow 26 and is pressed against the paper roll on spool 24 causing it to rotate in the indicated direction.
  • spool 24 When spool 24 has been filled to the desired capacity with paper from web 20, it is necessary to cut web 20 laterally, transfer the leading cut edge to an empty spool 27, and start the web winding on that spool in the direction of arrow 28 to eventually produce another filled spool, such as spool 24.
  • Empty spool 27 is positioned vertically above the location shown in FIG. 1 until it is ready to accept paper from web 20 and begin winding it up.
  • Spool 27, which may or may not be separately rotated as known in the art, is lowered until it contacts driving roll 23 and rotates with it, as shown in FIG. 1.
  • the cut edge of web 20 is then pushed into the nip 29 between empty spool 27 and driving roll 23, causing it to be wound onto spool 27 and to cause a transfer of the paper web thereto.
  • the illustrated apparatus of this invention generally includes a means for supplying a cutting tape 30 to the far edge of empty spool 27 and for causing that tape to wrap around spool 27 in a spiral fashion so as to cut web 20 and cause the cut edge to be introduced onto spool 27 and be wrapped about spool 27.
  • a supply of cutting tape 30 is preferably maintained on a removable drum 31 in a housing 32 which also serves to support a cutting means 33 which, at the appropriate time, cuts tape 30 from the large supply on drum 31.
  • Tape 30 passes through cutting means 33, adhesive application means 39 (shown outside of housing 32 for illustration purposes only and preferably located within the confines of housing 32, as would, be understood by persons having ordinary skill in the art) and into forward end 36' of a guideway 34 propelled by a driving means, e.g., hand crank 35 to cause the free end of tape 30 to move completely across the width of web 20 underneath that web in guideway 34 until it reaches the far end 36 where the free end 37 of tape 30 is made available to be inserted into nip 29 between spool 27 and driving roll 23.
  • a driving means e.g., hand crank 35
  • an adhesive strip 38 is applied to forward end 37 of tape 30 so that when it is introduced into nip 29 it will adhere to the surface of empty spool 27.
  • a clamping means in the form of a mechanical arm 40 is mounted on a stand 41 and has a hand 42 which grips tape 30, and on command extends hand 42 toward nip 29 until tape 30 is caught in nip 29 and is adhered to the surface of empty spool 27.
  • a frictional resistance is then applied to the tape 30 adjacent near end 44, e.g., the frictional resistance produced when tape 30 is dislodged from guideway 34, causing the tape 30 to spiral across the length of empty spool 27 and cut through web 20 as it does so and causes a transference of web 20 onto empty spool 27.
  • FIG. 2 is a schematic illustration of a first embodiment of the adhesive applicator 39 of FIG. 1.
  • Cutting tape 30 is in a channel guide 43 anywhere between cutter 33 and preferably the near end 44 of the main elongated guideway 34.
  • An opening 45 in channel guide 43 exposes the central portion of the lower surface of tape 30.
  • Roller 46 is suitably rotatably mounted so that its outer surface is in opening 45 with its outer portions also immersed in a pool of liquid adhesive 47 in reservoir 48.
  • Above tape 30 in vertical alignment with opening 45 is a pressure roller 49 mounted on arms 50 which are selectively movable from a retracted remote upward position 51 (shown in broken lines) to a downward pressure position as shown in solid lines in FIG. 2.
  • the pressure position presses tape 30 downwardly to contact roller 46 causing adhesive 47 to be coated onto the bottom surface of tape 30 for a selected length and width, preferably an adhesive strip, such as illustrated by 38 in FIG. 5.
  • Strip 38 is spaced inwardly of the side edges of the tape 30 so that the adhesive will not contact the guideways through which it passes, as hereinafter more fully described.
  • FIG. 3 there is a second embodiment of the adhesive applicator.
  • Tape 30 passes in a channel guide 52 having an opening 53 in the lower side to expose tape 30 to the action of spray nozzles 54 which spray adhesive 55 onto tape 30.
  • cutter 33 would be located immediately forward of opening 53 so that when the preceding length of tape 30 is cut, the adhesive 55 may be applied to form a strip of adhesive coating immediately behind the cut and thereby will form the forward end 37 (see FIG. 1) for the next length of tape 30 to be used in cutting the web 30 and starting it to roll onto empty spool 27.
  • Another version would be to advance the tape 30 after cutting to a position where the adhesive 55 is applied prior to advancing the tape through main elongated guideway 34.
  • FIG. 4 there is shown a preferred design of guideway 34 for use with adhesive applicators which apply the adhesive to the underneath surface of tape 30 as in FIGS. 2, 3 and 6.
  • the purpose of applying the adhesive to the lower surface of tape 30 is that when using certain designs of mechanical arm 40 with a telescopically extensible hand 42 it is easier to present tape 30 to hand 42 with the adhesive side facing hand 42 so it can be fed into nip 29 with the adhesive side facing upward to contact empty spool 27. More importantly in paper making, the attendant side of the machine is the near side where housing 32 and spool 31 of tape 30 is located, with the far side having the belts and pulleys to drive the rolls, etc.
  • Guideway 34 has an internal channel 56 with a rectangular cross section designed to permit tape 30 to slide lengthwise therein.
  • An elongated slot 57 is parallel to channel 56 and communicates between channel 56 and the outside atmosphere.
  • undercut recess 58 which is as wide as the adhesive coating 38.
  • tape 30 can slide through guideway 34 in channel 56 with its adhesive-free edges 61 (see Fig.5) supported on surfaces 56a of the channel 56 ie without having the adhesive coating adhere to any guideway 34.
  • An added feature is the provision of a resilient flap cover 59 held in place by spring clip 60. Flap cover 59 keeps dirt out of channel 56 and yet will flex upwardly and not inhibit the removal of tape 30 through slot 57 when that occurs during cutting of the paper web. Also, flap cover 59 provides protection from debris and moisture of the paper tape 30 during its travel through guideway 34.
  • FIG. 5 shows tape 30 with a coating 38 where adhesive has been applied at forward end 37. It may be seen that the lengthwise edges 61 are not covered with adhesive and thereby are available to support tape 30 as it slides in channel 56 as clearly shown in FIG. 4.
  • FIGS. 6-8 A third embodiment of a means for applying adhesive to tape 30 is shown in FIGS. 6-8.
  • Tape 30 is supported in a channel 62 having an opening 63 to expose the underneath side of tape 30.
  • Hold down roller 64 maintains a slight pressure downward on tape 30 above opening 63.
  • Supply spindle 65 carries a roll of double-sided pressure-sensitive tape 66 which includes a continuous release binder 67 and a plurality of lengths of pressure sensitive adhesive preferably separated from each successive length 68 by a short space 69 where no adhesive is on release binder 67.
  • Tape 66 is fed from spindle 65 over pressure roller 70 rotatably mounted on arms 71 which can move from the downward inoperative position 72 (in broken lines) to the upward operative position in solid lines.
  • the adhesive section 68 is pressed onto tape 30 while release tape 67 is rolled onto spool 73.
  • arms 71 move to the inoperative position 72 and spindle 65 is stopped until needed again.
  • Spindle 65 is shown as driving spool 73 by belt 74. It is to be understood that the double sided adhesive may simply be perforated, rather than spaced, in which event the trailing adhesive length 68 will be parted from the adhesive length 68 applied to tape 30 due to advancement of tape 30 after roller 70 moves to its inoperative position 72.
  • FIGS. 9-10 there is shown a fourth embodiment for applying adhesive to tape 30 employing a double-sided pressure sensitive tape 66 as shown in FIGS. 7 and 8.
  • a pressure roller 75 is mounted to apply pressure to tape 30 while in channel guide 43 lying above a length of double-sided adhesive tape 66 also in channel guide 43.
  • release tape 67 is peeled away, tape 30 is left with a specific portion of its bottom side coated with adhesive as at 38 in FIG. 5 which is then available to be forwarded to the nip 29 of rolls 23 and 27 to cut web 20 and start spooling the web 20 on roll 27.
  • double-sided adhesive tape 66 is fed from spindle 65 into the undercut recess 58 at the bottom of channel guide 43 to a forward location 87, with release tape 67 between recess 58 and the upward facing strip of adhesive 68 see FIGS. 7-8).
  • Tape 30 is then advanced in internal channel 56 over the top of tape 66 in recess 58 and stopped with its forward cut end at 87.
  • Handle 80 is then pushed forward to position 81 where pressure roller 75 is pressing downward on tape 30 over the width of recess 58, and the handle 80 pushed forward to position 82.
  • roller 75 By reason of the pivoting about rollers 78 in rails 77 this movement causes roller 75 to press down tape 30 into recess 58 to contact adhesive portion 68 of double-sided tape 66 and cause adhesive tape 66 to stick to tape 30.
  • Rolls 76 are sized to eventually touch the top of channel guide 43 and prevent roll 75 from applying more pressure on tape 30 than that necessary to pick up adhesive tape 66.
  • Handle 80 is then pulled back to its original position and released in its upright position (solid lines) which allows tape 30 to return to its original undeformed flat condition not pressed into recess 58.
  • FIGS. 2, 3, 6, 9 and 10 are preferred embodiments, but other means, mechanical, manual, or otherwise are operative. It is only necessary to this invention that the adhesive strip be applied before the tape reaches near end 44 of guideway 34. This is a safety measure to permit all operations to be controlled by an operator located adjacent near end 44 without ever needing to be present at the far end of guideway 34.
  • FIG. 11 Another clamping means is shown in FIG. 11.
  • An angle support structure 155 extends outwardly from far end 36 (having a different bend or configuration from end 36 of FIG. 1) of guideway 34.
  • a motor 156 and gear box 157 provide the power to rotate knurled cylinder 158 mounted on a shaft 159.
  • Tape 30 moves forward between cylinder 158 and table 160 pivotally mounted at 159 to structure 155 until forward cutting tape end 37 extends beyond table 160. Movement of tape 30 is then stopped by table 160 being pressed upward against cylinder 158 causing a large loop 161 of tape 30 to build up behind cylinder 158.
  • Table 160 is pivoted about pin 162 by the upward movement of a head (not shown) connected to a fluid operated cylinder 164.
  • Table 160 moves from its normal position to an upward position shown in FIG. 11 where it presses tape 30 against cylinder 158 to stop forward movement of tape 30.
  • cylinder 158 When the operator wants to introduce leading end 37 into the nip 29 cylinder 158 is caused to rotate in the direction of arrow 168 against an idler roller (not shown) in table 160 and thereby to advance leading end 37.
  • leading end 37 contacts nip 29 the tape 30 is pulled sidewise away from the clamping means and is wrapped spirally around roll 27, cutting web 20 and starting the cut edge of web 20 to be rolled up onto spool 27.
