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.

Abstract
Description
- 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.
- It is a general practice in the paper industry to produce a continuous sheet or web of paper which is wound onto large spools. In order to have a continuous operation it is, of course, necessary to have a system for instantaneously switching from winding the web of paper onto a full roll to an empty roll, particularly at modern speeds of paper production. In US-A-2,461,246 there is shown a method of feeding a tape onto the rotating empty roll core and causing it to be spirally wrapped on that core as it stretches tight across the travelling web of paper and cuts the paper, with the cut edge being led onto the empty roll supported by the cutting tape. Subsequent improvements have dealt with methods of stringing the tape for cutting and feeding, and the use of various types of tapes, as shown for example in US-A-4,414,258 where there is described a tape made of repulpable paper woven into a tape which did not interfere with the paper making process since the paper wound adjacent the roll is waste and is recycled. The most recent improvement is disclosed in my US-A-4,659,029 which describes the use of a repulpable paper fiber tape in an elongated guideway to direct the tape under a travelling web of paper and direct the tape into the nip of an empty spool so as to cut the web of paper and start it rolling onto the empty spool.
- More particularly, 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.
- More particularly, 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.
- In preferred embodiments of the apparatus of the present invention, 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.
- Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, in which:
- FIG. 1 is a perspective view of the system of rollers employed in the paper industry to wind the paper web onto rolls, and showing a first embodiment of the present apparatus used to transfer the leading edge of the web to an empty spool;

- FIG. 10 is a cross section taken at 10--10 of FIG. 9; and
- FIG. 11 is a partial perspective view showing another clamping means to feed the cutting tape into the nip.
- The general features of the illustrated embodiments of this invention are best seen and understood by reference to FIG. 1 which 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 towardtension roll 21 mounted in journals onsupports 22, leadingweb 20 overdriving roll 23 and winding aboutspool 24 turning in the direction ofarrow 25.Driving roll 23 turns in the direction ofarrow 26 and is pressed against the paper roll onspool 24 causing it to rotate in the indicated direction. Whenspool 24 has been filled to the desired capacity with paper fromweb 20, it is necessary to cutweb 20 laterally, transfer the leading cut edge to anempty spool 27, and start the web winding on that spool in the direction ofarrow 28 to eventually produce another filled spool, such asspool 24.Empty spool 27 is positioned vertically above the location shown in FIG. 1 until it is ready to accept paper fromweb 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 drivingroll 23 and rotates with it, as shown in FIG. 1. The cut edge ofweb 20 is then pushed into thenip 29 betweenempty spool 27 and drivingroll 23, causing it to be wound ontospool 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 ofempty spool 27 and for causing that tape to wrap aroundspool 27 in a spiral fashion so as to cutweb 20 and cause the cut edge to be introduced ontospool 27 and be wrapped aboutspool 27. A supply ofcutting tape 30 is preferably maintained on aremovable drum 31 in ahousing 32 which also serves to support acutting means 33 which, at the appropriate time, cutstape 30 from the large supply ondrum 31. It will be appreciated that only a definite length of tape, longer than the width ofweb 20, is needed to cut acrossweb 20 laterally and to cause the cut edge to begin wrapping itself uponempty spool 27, and thus at theappropriate place tape 30 is cut and further tape is not needed untilspool 27 becomes filled with paper and must be replaced by another empty spool.Tape 30 passes throughcutting means 33, adhesive application means 39 (shown outside ofhousing 32 for illustration purposes only and preferably located within the confines ofhousing 32, as would, be understood by persons having ordinary skill in the art) and into forward end 36' of aguideway 34 propelled by a driving means, e.g.,hand crank 35 to cause the free end oftape 30 to move completely across the width ofweb 20 underneath that web inguideway 34 until it reaches thefar end 36 where thefree end 37 oftape 30 is made available to be inserted intonip 29 betweenspool 27 and drivingroll 23. As seen in FIG. 5, anadhesive strip 38 is applied toforward end 37 oftape 30 so that when it is introduced intonip 29 it will adhere to the surface ofempty spool 27. In a preferred embodiment a clamping means in the form of amechanical arm 40 is mounted on astand 41 and has ahand 42 which grips tape 30, and on command extendshand 42 towardnip 29 untiltape 30 is caught innip 29 and is adhered to the surface ofempty spool 27. A frictional resistance is then applied to thetape 30 adjacent near end 44, e.g., the frictional resistance produced whentape 30 is dislodged fromguideway 34, causing thetape 30 to spiral across the length ofempty spool 27 and cut throughweb 20 as it does so and causes a transference ofweb 20 ontoempty 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 achannel guide 43 anywhere betweencutter 33 and preferably the near end 44 of the mainelongated guideway 34. Anopening 45 inchannel guide 43 exposes the central portion of the lower surface oftape 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 ofliquid adhesive 47 inreservoir 48. Abovetape 30 in vertical alignment withopening 45 is apressure roller 49 mounted onarms 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 pressestape 30 downwardly to contactroller 46 causing adhesive 47 to be coated onto the bottom surface oftape 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 thetape 30 so that the adhesive will not contact the guideways through which it passes, as hereinafter more fully described. In FIG. 3 there is a second embodiment of the adhesive applicator.Tape 30 passes in achannel guide 52 having anopening 53 in the lower side to exposetape 30 to the action ofspray nozzles 54 which sprayadhesive 55 ontotape 30. In one version of this system,cutter 33 would be located immediately forward of opening 53 so that when the preceding length oftape 30 is cut, theadhesive 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 oftape 30 to be used in cutting theweb 30 and starting it to roll ontoempty spool 27. Another version would be to advance thetape 30 after cutting to a position where theadhesive 55 is applied prior to advancing the tape through mainelongated guideway 34. - In FIG. 4 there is shown a preferred design of
guideway 34 for use with adhesive applicators which apply the adhesive to the underneath surface oftape 30 as in FIGS. 2, 3 and 6. The purpose of applying the adhesive to the lower surface oftape 30 is that when using certain designs ofmechanical arm 40 with a telescopicallyextensible hand 42 it is easier to presenttape 30 tohand 42 with the adhesiveside facing hand 42 so it can be fed intonip 29 with the adhesive side facing upward to contactempty spool 27. More importantly in paper making, the attendant side of the machine is the near side wherehousing 32 andspool 31 oftape 30 is located, with the far side having the belts and pulleys to drive the rolls, etc. Refilling thespool 31 with tape, adding adhesive toreservoir 48 and the like from the near side enhances the efficiencies of the disclosed apparatus and method and greatly increases the safety in use. Guideway 34 has aninternal channel 56 with a rectangular cross section designed to permittape 30 to slide lengthwise therein. Anelongated slot 57 is parallel tochannel 56 and communicates betweenchannel 56 and the outside atmosphere. Whentape 30 has been caught innip 29 and starts to wind onempty spool 27tape 30 will be pulled laterally out ofchannel 56 throughslot 57, and thereby produces the frictional resistance necessary to causetape 30 to wind spirally aroundspool 27 cuttingweb 20 and starting the cut edge to wrap ontospool 27. In this embodiment of the invention there is anundercut recess 58 which is as wide as theadhesive coating 38. In thisway tape 30 can slide throughguideway 34 inchannel 56 with its adhesive-free edges 61 (see Fig.5) supported on surfaces 56a of thechannel 56 ie without having the adhesive coating adhere to anyguideway 34. An added feature is the provision of aresilient flap cover 59 held in place byspring clip 60.Flap cover 59 keeps dirt out ofchannel 56 and yet will flex upwardly and not inhibit the removal oftape 30 throughslot 57 when that occurs during cutting of the paper web. Also,flap cover 59 provides protection from debris and moisture of thepaper tape 30 during its travel throughguideway 34. - FIG. 5 shows
tape 30 with acoating 38 where adhesive has been applied atforward end 37. It may be seen that thelengthwise edges 61 are not covered with adhesive and thereby are available to supporttape 30 as it slides inchannel 56 as clearly shown in FIG. 4. - 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 oftape 30. Hold down roller 64 maintains a slight pressure downward ontape 30 above opening 63.Supply spindle 65 carries a roll of double-sided pressure-sensitive tape 66 which includes acontinuous 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 onrelease binder 67.Tape 66 is fed fromspindle 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. Astape 66 passes between roller 70 andtape 30, the adhesive section 68 is pressed ontotape 30 whilerelease tape 67 is rolled ontospool 73. When a section 68 of adhesive is applied totape 30, arms 71 move to the inoperative position 72 andspindle 65 is stopped until needed again.Spindle 65 is shown as drivingspool 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 oftape 30 after roller 70 moves to its inoperative position 72. - In 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. Apressure roller 75 is mounted to apply pressure to tape 30 while inchannel guide 43 lying above a length of double-sidedadhesive tape 66 also inchannel guide 43. Afterrelease 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 ofrolls web 20 and start spooling theweb 20 onroll 27. In this embodiment double-sidedadhesive tape 66 is fed fromspindle 65 into the undercutrecess 58 at the bottom ofchannel guide 43 to aforward location 87, withrelease tape 67 betweenrecess 58 and the upward facing strip of adhesive 68 see FIGS. 7-8).Tape 30 is then advanced ininternal channel 56 over the top oftape 66 inrecess 58 and stopped with its forward cut end at 87.Handle 80 is then pushed forward to position 81 wherepressure roller 75 is pressing downward ontape 30 over the width ofrecess 58, and thehandle 80 pushed forward toposition 82. By reason of the pivoting aboutrollers 78 inrails 77 this movement causesroller 75 to press downtape 30 intorecess 58 to contact adhesive portion 68 of double-sided tape 66 and causeadhesive tape 66 to stick totape 30.Rolls 76 are sized to eventually touch the top ofchannel guide 43 and preventroll 75 from applying more pressure ontape 30 than that necessary to pick upadhesive tape 66.Handle 80 is then pulled back to its original position and released in its upright position (solid lines) which allowstape 30 to return to its original undeformed flat condition not pressed intorecess 58. In returning to its original position one ofsupports 79 pushes onhead 83 causingcontact pad 88 to touchcontact plate 85 providing electric power to a means (not shown) to turnspool 73 in the direction orarrow 89. This causesrelease tape 67 to be stripped from the adhesive stuck totape 30, and at the same time, to advance the next section 68 of two-sidedadhesive tape 66 alongrecess 58 to forwardposition 87. The means of turningspindle 65 andspool 73 simultaneously is shown as a V-belt 86 operating inpulleys 90. Obviously other driving means such as gears, chain-and-sprocket, and the like can be employed for the same purpose. This finishes the cycle and preparestape 30 for advancement to nip 29 to cutweb 20 and start rolling it ontospool 27, while a new section oftape 30 is advanced to point 87 to have an adhesive spot applied to it. - Several embodiments have been shown for applying a strip of adhesive to cutting
tape 30. It is to be understood that other means may be equally operative and are intended to be included in this invention. The means shown in 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 ofguideway 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 ofguideway 34. - 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 fromend 36 of FIG. 1) ofguideway 34. Amotor 156 andgear box 157 provide the power to rotateknurled cylinder 158 mounted on ashaft 159.Tape 30 moves forward betweencylinder 158 and table 160 pivotally mounted at 159 to structure 155 until forward cuttingtape end 37 extends beyond table 160. Movement oftape 30 is then stopped by table 160 being pressed upward againstcylinder 158 causing alarge loop 161 oftape 30 to build up behindcylinder 158. Table 160 is pivoted about pin 162 by the upward movement of a head (not shown) connected to a fluid operatedcylinder 164. Table 160 moves from its normal position to an upward position shown in FIG. 11 where it pressestape 30 againstcylinder 158 to stop forward movement oftape 30. When the operator wants to introduce leadingend 37 into the nip 29cylinder 158 is caused to rotate in the direction ofarrow 168 against an idler roller (not shown) in table 160 and thereby to advance leadingend 37. When leadingend 37 contacts nip 29 thetape 30 is pulled sidewise away from the clamping means and is wrapped spirally aroundroll 27, cuttingweb 20 and starting the cut edge ofweb 20 to be rolled up ontospool 27.
