Description
Technical Domain The present invention relates to a procedure for changing winding rolls on machines that are used to wind webs of material, in particular paper or cardboard, onto cores, and an apparatus for carrying out this procedure.
In winding machinery used to wind webs of material to form winding rolls, every attempt is made to minimize the machine downtime that is required to change these winding rolls. When this is done, it must be ensured that the new web start that is created by separation is secured firmly to the new winding core and/or the web end is secured to the full winding roll.
Dr;~r Try DE 36 11 895-Al describes a procedure of this kind that is used for support roll winding machines, in which the web is first weakened before it reaches the support roll, an adhesive track is applied to both sides of the weakened area, and the web is then separated on the support roll by braking the roll. The web end that is held on the support roll by a partial vacuum is moved to the full winding roll and glued to this. The newly created web starts remain braked during this movement until the finished roll has been removed and new cores have been installed and the brake is released, so that the web starts (to which an adhesive strip has been applied) are moved from the support roll to the winding core and glued to it.
DE 40 03 504-A1 describes a support roll winder in which there is a perforating system on the in-run side and in which there is a plurality of adhesive tape dispensers that are used to apply double-sided adhesive tapes s~
transversely across the working width; these dispensers dispense their adhesive tapes in the direction of movement of the web. Thus, the attachment of the adhesive tapes can be effected by means of the web that is moved.
In the case of paper or cardboard webs it has been shown that it is necessary to have either a continuaus wide adhesive strip across the width of the web or, in the case of application in the direction of movement of the web, an adhesive strip every 200 mm. In the case of large web widths, e.g.,-8 m, it requires a great deal of time to apply a transverse adhesive strip or, in the case of application in the direction of movement of the web, it is necessary to have a large number of adhesive tape dispensers.
Summary of the Invention It is the task of the present invention to so improve a procedure of this kind that only one adhesive tape dispenser is required to apply the adhesive strips, and such that machinery downtimes are not extended.
The invention provides a method of winding a continuous web on a succession of cores comprising the steps of: (a) longitudinally advancing the web looped about a working width of a guide roll to wind it in a winding roll resting on the guide roll; (b) interrupting advance of the web and forming at a perforation station a crosswise perforation row in the web across the working width; (c) longitudinally advancing a carrier tape with a twoface adhesive thereon in a loop about a pressure roller; (d) thereafter urging the pressure roller toward a transfer roller extending across the working width and spaced from the guide roll and downstream of the perforation station to press and adhere the adhesive to the transfer roller; (e) pulling the pressure roller away from the transfer roller, detaching thereby the carrier tape from the adhesive on the transfer roller; (f) thereafter displacing the pressure roller transversely to the longitudinal advance of the web and repeating the steps (d) and (e) at subsequent delivery locations, thereby forming a plurality of adhesive strips spaced from one another and aligned along said working width on the transfer roller; (g) then swinging the transfer roller toward the web to press the plurality of strips against the web for straddling both sides of the perforation row on the web upon resuming an advance of the web, thereby adhering the plurality of strips on the web along the working width; (h) thereafter withdrawing the transfer roller from the web while longitudinally advancing the web with the plurality of strips adhered thereto toward the first winding roll; (i) thereafter tearing the web longitudinally apart at the perforation row, forming thereby trailing and leading web ends; (j) thereafter attaching the trailing web end to the winding roll and the leading end to a core to be wound; and (k) repeating steps (b) thraugh (j).
The invention also provides a method of winding a continuous web on a succession of cores comprising t;he steps of: (a) longitudinally advancing the web looped about a working width of a guide roll along a web path to wind it in a winding roll resting on the guide roll; (b) interrupting advance of the web and forming at a perforation station located upstream of the winding roll a crosswise perforation row in the web across the working width; (c) activating dispatching means for applying a twoface adhesive strip on a transfer roll spaced from the web and located along the web path downstream of the perforation station; (d) thereafter displacing the dispatching means transversely to the longitudinal advance of the web and repeating the si~ep (c) at subsequent delivery locations, thereby forming a plurality of adhesive strips spaced from one another; (e) while displacing the dispatching means toward a subsequent delivery location rotating the transfer roll to apply a respective subsequent adhesive strip at the respective location in alignment with the previous one across the working width; (f) then swinging the transfer element toward the web to press the plurality of spaced apart and aligned strips against the web for straddling both sides of the perforation row on the web upon resuming an advance of the web, thereby adhering the row of strips on the web along the working width; (g) thereafter withdrawing the transfer roller from the web while longitudinally advancing the web with the plurality of strips adhered thereto toward the first winding roll; (h) thereafter tearing the web longitudinally apart at the perforation row, forming thereby trailing and leading web ends; (i) thereafter attaching the trailing web end to the winding roll and the leading end to a core to be wound; and (j) repeating steps (b) through (i).
According to the present invention, only one adhesive dispenser is required and this first applies the adhesive strip to the transfer element. This can be done when the web of material is being wound up, so that machine downtimes are not extended. In the event that a roll change takes place at shorter intervals than are required for the application of the adhesive strips to the transfer element, two adhesive dispensers that apply adhesive strips onto the transfer element from both sides simultaneously, across the working width.
In an advantageous variant for the roll change in the case of heavier grades of paper, e.g., cardboard, the web is first weakened and strips of adhesive are applied on n.
both sides of this break line. The break line can then be moved into the position that is desired for cementing the new web starts to the new cores. After the web has been separated, both ends that are formed have adhesive strips applied to them: the web end, for cementing to the full winding roll; and the newly created web start, for cementing to the new winding core. A particularly advantageous variant of the procedure described to change full winding rolls for new winding sleeves in support roll winders with two powered support rolls, on which the winding rolls lie during the winding procedure.
The invention also provides an apparatus for winding a continuous web on a succession of cores comprising: drive means including a guide roll for longitudinally advancing a web extending across a working width of the guide roll to wind the web in a winding roll resting on the guide roll; cutting means upstream of the winding roll for forming a crosswise perforation row across the working width; a transfer roll along the path between the cutting means and the winding roll and juxtaposed with the guide roll across the working width, the transfer roll being spaced from the web in a receiving position and being swingable toward the web in a transferring position.; a pressure roll longitudinally guiding a carrier tape with a twoface adhesive strip thereon toward the transfer roll;
displacing means for sequential displacement of the pressure roll transversely across the working width between a plurality of delivery locations spaced apart across the working width; actuator means for displacing the pressure roll toward the transfer roll to urge the carrier against the transfer roll in the receiving position thereof: at each of the locations, and away from the transfer roll to detach the carrier from the adhesive, forming thereby a plurality 5a a~
of spaced apart and aligned adhesives strips on the transfer roll across the working width; swinging means for swinging the transfer roll in said transferring position to press the plurality of adhesive strips against the web, each of the adhesive strips straddling both sides of the perforation row upon running off the transfer roll; means for tearing the web longitudinally apart at the perforation row to form leading and trailing web ends each provided with respective adhesive strips; and means for pressing the trailing web end on the winding roll and the leading end against a fresh core by engaging the respective adhesive strips thereagainst.

Implementation of the Invention The support roll winder that is shown partially sectioned in the drawing incorporates two powered support rolls 1, 2 on which the winding rolls 3 lie during the winding procedure. The web 4 of material that is divided longitudinally into individual webs, and which is preferably of paper or cardboard, is deflected from below on the support roll l, through the gap between the support rolls l, 2 and into the roll bed 5 and then wound onto cores that are aligned. Such double support roll winders are familiar and are described, for example, in DE-OS 32 07 461, so that the details of these will not be described, to the extent that they do not apply to the present invention. Pivoting arms 6 are secured on both ends of the in-run side support roll 1, and these pivot about the support roll axis; these arms support a pivot cross-beam 7 that extends across the working width. On the upper side of the pivot cross-beam l there is a freely rotatable ejector roll 8 to eject the full winding roll 3 outwards, beyond the support roll 2. On the underside, the pivot cross-beam 7 supports a backing holder 9 that extends across the whole working width, for a perforator 10 that incorporates two supporting surfaces 11, 12 between which there is a groove. By pivoting tree 5c it pivot cross-bar 7 down the supporting surfaces 11, 12 can be moved against the web 4, as is shown i.n figure 2.
The perforator 10 incorporates a serrated blade 14 that extends across the whole working width, and this can be moved by means of the lift unit l5both away from the web 4, and also, as is shown in figure 2, into the groove of the lowered backing holder 9, in order to perforate the web 4. Two clamping elements 17, l8 that are spring mounted at the sides, adjacent to the blade 14, on the blade holder 16 serve to clamp the web 4 during the perforating procedure, and these can be pressed against the supparting surfaces 11, 12 of the backing holder 9.
Beneath the support roll 1 there is an apparatus 19 that is used to apply an adhesive. This incorporates a transfer roller 21 that extends across the whole working width and which is supported on pivot arms 20 so as to be rotatable by means of a drive, and this can be moved against the web 4 in the wrap-around area of the support roll 1. The surface of the transfer roller 21 is such that the adhesive adheres less to it than to the web of material 4, i.e., it has less adhesion than the web 4:
Figures 1 to 3, show that beneath the transfer roll 21 there is an adhesive tape dispenser 22 that is supported so a~; to be moveable on the guides 23, transversely across the working width, which is to say parallel to the support roll axis. I:n the version that is shown in figures 1 and 2, the adhesive tape 24 is guided in the direction of movement of the web 4. To this end, a supply roll 26 of adhesive tape 24 with a double-sided adhesive layer that adheres to a backing tape 27 is supported so as to be freely rotatable in the slide 25 that can be moved transversely to the web. The adhesive tapes that are familiar in the paper industry are used, and the adhesive layer can be removed very easily from the backing tape 27. The adhesive tape i.s guided upwards on the slide 25 and against the direction of movement of the web 4 as far as a pressure roll 28 that is of the same width as the adhesive tape, and this deflects it downwards to a driven core 29 for the backing tape 27. In order to apply the adhesive strips to the transfer roller 21, the pressure roll 28 is pivoted up against the transfer roller 21, which is in its lowered position, by means of a piston-cylinder unit 30.
In the event that shorter application times for the adhesive strip on the transfer roller 21 are required, e.g., because of shorter roll change times, two or more adhesive tape dispensers are arranged across the width of the machine, and these then operate simultaneously.
Figure 1 shows the support roll winder during the winding procedure: the perforator 10 and its backing holder 9 are at a distance from the web 4 at which they do not interfere with operation of the machine. The transfer roller 21 is lowered so that it, too, is spaced away from the web 4. In this position, several parallel strips 31 that are adhesive are applied to its surface longitudinally to the direction of movement of the web 4.
To this end, the pressure roll 28 around which the adhesive tape 24 is wrapped is pivoted from below against the transfer roll 21.
When the transfer roll 21 is rotated, the adhesive tape 24 is .
wound off the supply roll 26 and an adhesive strip 31 is picked up by the transfer roller 21. The remaining backing tape 27 is wound up by the spool 29. Once the desired length of adhesive strip is on the transfer roller 21, the pressure roll. 28 is pivoted down, which means that the adhesive layer is stripped off the backing tape 24. Then, the slide 25 moves transversely to the direction of movement of the web into the next adhesive strip dispensing position. At the same time, the transfer roll 21 is rotated back into the pick-up position, in order that the adhesive strips 31 that have picked up are aligned. Because of-the pressure exerted by the pressure roll 28, the next adhesive strip 31 is now transferred to the transfer roll 21. Depending on the width of the web 4, a number of adhesive strips 31 that are both parallel and transverse to the direction of movement of the web 4, and which are aligned, are applied to the transfer roll 20; it is preferred that this be done approximately every 200 mm. In the same way, it is also passible to so adjust the positions of the adhesive strips 31 as a function of the positions of the longitudinal blades that the adhesive strips 31 are distributed equally on the individual webs.
Once the winding roll 3 has reached a pre-set web length or a pre-set diameter, the support roll winder is stopped. Because of the braking force that is applied by a roll-off system (not shown herein), web 4 is under tension. Then, the pivot cross-bar 7 is pivoted downwards so that the supporting surfaces 11, 12 of the backing holder 9 lie on the web 4, and the web 4 is then weakened by perforation. To this end, the blade 14 moves upwards and its tips pass through the web 4 into the groove that is located between the supporting surfaces 11, 12. During perforation, the web 4 is clamped between the clamping elements 17, 18, and the supporting surfaces 11, 12 and is thus kept taut. At the same time, the transfer roller 21 pivots, as is shown in figure 2, from below against the support roll 1 and lies against the web 4.
When this is done, the transfer roll 21 is so rotated that the peripheral distance between the line of contact 32 with the web 4 and the middle of the adhesive strips 31 is approximately equal to the space between 'the line of contact 32 and the blade 14.
Then, the blade 14 together with the clamping elements 17, 18 is lowEred, and the transfer roll 21 is set to free wheel. The support roll 1 is then started at reduced web tension, whereupon the adjacent transfer roll 21 rotates with it. When this happens, the adhesive strips 31 are pressed on the line of contact under pressure against the web 4, whereupon they are released from the transfer roll 21 and adhere firmly to the web 4 because adhesion on the web 4 is greater than on the transfer roller 21. The perforated line 33 in the web 4 has meanwhile 2~~~~~
moved forward as far as the line of contact 32 and for this reason the adhesive strips 31 are on both aides of the perforated line 33 on the web 4 (figure 4).
After the transfer of the adhesive strips 31 to the web 4 the transfer roll 21 is lowered once again and in this position can pick up fresh adhesive strips fox the next roll change. The web 4 is moved further until such time as the weakened point of the web (perforated line 33) is located, with the adhesive strip 31, in the roller bed 5 above the gap between the two support rolls l, 2. There, the web 4 is stopped and the brake on the roll-off apparatus is applied in order to exert the maximal force. Then, the winding roll 3 with the ejector roll 9 is raised slightly from the wrapped-around support roll 1 and rotated by means of the support roll 2. When this happens, the web 4 separates on the perforated line 33 so that there is an adhesive strip 31 both on the out-running end of the web and on the newly-created web start. The newly-created web start is held on the support roll 1, which can be effected, for example, by suction generated by an under-pressure, or by means of mechanical retaining elements.
The full winding roll 3 is rotated further until the web end that has the adhesive strip 31 is moved through the line of contact to the support roll 1 or to the ejector roll 8 so that the web end is cemented to the full winding roll 3. Then, the full winding roll 3 together with the ejector roll 8 is ejected over the support roll 2 and a new set of cores is installed in the roll bed 5. After the positioning of a pressure roll (not shown herein), the support rolls 1, 2 are once again started in order that the new web start that has been provided with the adhesive strip 31 is brought into contact with the cores. A durable adhesive bond between the web 4 and the core is produced if the web start with the adhesive strips 31 has passed through the gap between the cores and the support roll 1. The support roll winder can then be accelerated to the maximal winding speed.
In winding machinery used to wind webs of material to form winding rolls, every attempt is made to minimize the machine downtime that is required to change these winding rolls. When this is done, it must be ensured that the new web start that is created by separation is secured firmly to the new winding core and/or the web end is secured to the full winding roll.
Dr;~r Try DE 36 11 895-Al describes a procedure of this kind that is used for support roll winding machines, in which the web is first weakened before it reaches the support roll, an adhesive track is applied to both sides of the weakened area, and the web is then separated on the support roll by braking the roll. The web end that is held on the support roll by a partial vacuum is moved to the full winding roll and glued to this. The newly created web starts remain braked during this movement until the finished roll has been removed and new cores have been installed and the brake is released, so that the web starts (to which an adhesive strip has been applied) are moved from the support roll to the winding core and glued to it.
DE 40 03 504-A1 describes a support roll winder in which there is a perforating system on the in-run side and in which there is a plurality of adhesive tape dispensers that are used to apply double-sided adhesive tapes s~
transversely across the working width; these dispensers dispense their adhesive tapes in the direction of movement of the web. Thus, the attachment of the adhesive tapes can be effected by means of the web that is moved.
In the case of paper or cardboard webs it has been shown that it is necessary to have either a continuaus wide adhesive strip across the width of the web or, in the case of application in the direction of movement of the web, an adhesive strip every 200 mm. In the case of large web widths, e.g.,-8 m, it requires a great deal of time to apply a transverse adhesive strip or, in the case of application in the direction of movement of the web, it is necessary to have a large number of adhesive tape dispensers.

Implementation of the Invention The support roll winder that is shown partially sectioned in the drawing incorporates two powered support rolls 1, 2 on which the winding rolls 3 lie during the winding procedure. The web 4 of material that is divided longitudinally into individual webs, and which is preferably of paper or cardboard, is deflected from below on the support roll l, through the gap between the support rolls l, 2 and into the roll bed 5 and then wound onto cores that are aligned. Such double support roll winders are familiar and are described, for example, in DE-OS 32 07 461, so that the details of these will not be described, to the extent that they do not apply to the present invention. Pivoting arms 6 are secured on both ends of the in-run side support roll 1, and these pivot about the support roll axis; these arms support a pivot cross-beam 7 that extends across the working width. On the upper side of the pivot cross-beam l there is a freely rotatable ejector roll 8 to eject the full winding roll 3 outwards, beyond the support roll 2. On the underside, the pivot cross-beam 7 supports a backing holder 9 that extends across the whole working width, for a perforator 10 that incorporates two supporting surfaces 11, 12 between which there is a groove. By pivoting tree 5c it pivot cross-bar 7 down the supporting surfaces 11, 12 can be moved against the web 4, as is shown i.n figure 2.
The perforator 10 incorporates a serrated blade 14 that extends across the whole working width, and this can be moved by means of the lift unit l5both away from the web 4, and also, as is shown in figure 2, into the groove of the lowered backing holder 9, in order to perforate the web 4. Two clamping elements 17, l8 that are spring mounted at the sides, adjacent to the blade 14, on the blade holder 16 serve to clamp the web 4 during the perforating procedure, and these can be pressed against the supparting surfaces 11, 12 of the backing holder 9.
Beneath the support roll 1 there is an apparatus 19 that is used to apply an adhesive. This incorporates a transfer roller 21 that extends across the whole working width and which is supported on pivot arms 20 so as to be rotatable by means of a drive, and this can be moved against the web 4 in the wrap-around area of the support roll 1. The surface of the transfer roller 21 is such that the adhesive adheres less to it than to the web of material 4, i.e., it has less adhesion than the web 4:
Figures 1 to 3, show that beneath the transfer roll 21 there is an adhesive tape dispenser 22 that is supported so a~; to be moveable on the guides 23, transversely across the working width, which is to say parallel to the support roll axis. I:n the version that is shown in figures 1 and 2, the adhesive tape 24 is guided in the direction of movement of the web 4. To this end, a supply roll 26 of adhesive tape 24 with a double-sided adhesive layer that adheres to a backing tape 27 is supported so as to be freely rotatable in the slide 25 that can be moved transversely to the web. The adhesive tapes that are familiar in the paper industry are used, and the adhesive layer can be removed very easily from the backing tape 27. The adhesive tape i.s guided upwards on the slide 25 and against the direction of movement of the web 4 as far as a pressure roll 28 that is of the same width as the adhesive tape, and this deflects it downwards to a driven core 29 for the backing tape 27. In order to apply the adhesive strips to the transfer roller 21, the pressure roll 28 is pivoted up against the transfer roller 21, which is in its lowered position, by means of a piston-cylinder unit 30.
In the event that shorter application times for the adhesive strip on the transfer roller 21 are required, e.g., because of shorter roll change times, two or more adhesive tape dispensers are arranged across the width of the machine, and these then operate simultaneously.
Figure 1 shows the support roll winder during the winding procedure: the perforator 10 and its backing holder 9 are at a distance from the web 4 at which they do not interfere with operation of the machine. The transfer roller 21 is lowered so that it, too, is spaced away from the web 4. In this position, several parallel strips 31 that are adhesive are applied to its surface longitudinally to the direction of movement of the web 4.
To this end, the pressure roll 28 around which the adhesive tape 24 is wrapped is pivoted from below against the transfer roll 21.
When the transfer roll 21 is rotated, the adhesive tape 24 is .
wound off the supply roll 26 and an adhesive strip 31 is picked up by the transfer roller 21. The remaining backing tape 27 is wound up by the spool 29. Once the desired length of adhesive strip is on the transfer roller 21, the pressure roll. 28 is pivoted down, which means that the adhesive layer is stripped off the backing tape 24. Then, the slide 25 moves transversely to the direction of movement of the web into the next adhesive strip dispensing position. At the same time, the transfer roll 21 is rotated back into the pick-up position, in order that the adhesive strips 31 that have picked up are aligned. Because of-the pressure exerted by the pressure roll 28, the next adhesive strip 31 is now transferred to the transfer roll 21. Depending on the width of the web 4, a number of adhesive strips 31 that are both parallel and transverse to the direction of movement of the web 4, and which are aligned, are applied to the transfer roll 20; it is preferred that this be done approximately every 200 mm. In the same way, it is also passible to so adjust the positions of the adhesive strips 31 as a function of the positions of the longitudinal blades that the adhesive strips 31 are distributed equally on the individual webs.
Once the winding roll 3 has reached a pre-set web length or a pre-set diameter, the support roll winder is stopped. Because of the braking force that is applied by a roll-off system (not shown herein), web 4 is under tension. Then, the pivot cross-bar 7 is pivoted downwards so that the supporting surfaces 11, 12 of the backing holder 9 lie on the web 4, and the web 4 is then weakened by perforation. To this end, the blade 14 moves upwards and its tips pass through the web 4 into the groove that is located between the supporting surfaces 11, 12. During perforation, the web 4 is clamped between the clamping elements 17, 18, and the supporting surfaces 11, 12 and is thus kept taut. At the same time, the transfer roller 21 pivots, as is shown in figure 2, from below against the support roll 1 and lies against the web 4.
When this is done, the transfer roll 21 is so rotated that the peripheral distance between the line of contact 32 with the web 4 and the middle of the adhesive strips 31 is approximately equal to the space between 'the line of contact 32 and the blade 14.
Then, the blade 14 together with the clamping elements 17, 18 is lowEred, and the transfer roll 21 is set to free wheel. The support roll 1 is then started at reduced web tension, whereupon the adjacent transfer roll 21 rotates with it. When this happens, the adhesive strips 31 are pressed on the line of contact under pressure against the web 4, whereupon they are released from the transfer roll 21 and adhere firmly to the web 4 because adhesion on the web 4 is greater than on the transfer roller 21. The perforated line 33 in the web 4 has meanwhile 2~~~~~
moved forward as far as the line of contact 32 and for this reason the adhesive strips 31 are on both aides of the perforated line 33 on the web 4 (figure 4).
After the transfer of the adhesive strips 31 to the web 4 the transfer roll 21 is lowered once again and in this position can pick up fresh adhesive strips fox the next roll change. The web 4 is moved further until such time as the weakened point of the web (perforated line 33) is located, with the adhesive strip 31, in the roller bed 5 above the gap between the two support rolls l, 2. There, the web 4 is stopped and the brake on the roll-off apparatus is applied in order to exert the maximal force. Then, the winding roll 3 with the ejector roll 9 is raised slightly from the wrapped-around support roll 1 and rotated by means of the support roll 2. When this happens, the web 4 separates on the perforated line 33 so that there is an adhesive strip 31 both on the out-running end of the web and on the newly-created web start. The newly-created web start is held on the support roll 1, which can be effected, for example, by suction generated by an under-pressure, or by means of mechanical retaining elements.
The full winding roll 3 is rotated further until the web end that has the adhesive strip 31 is moved through the line of contact to the support roll 1 or to the ejector roll 8 so that the web end is cemented to the full winding roll 3. Then, the full winding roll 3 together with the ejector roll 8 is ejected over the support roll 2 and a new set of cores is installed in the roll bed 5. After the positioning of a pressure roll (not shown herein), the support rolls 1, 2 are once again started in order that the new web start that has been provided with the adhesive strip 31 is brought into contact with the cores. A durable adhesive bond between the web 4 and the core is produced if the web start with the adhesive strips 31 has passed through the gap between the cores and the support roll 1. The support roll winder can then be accelerated to the maximal winding speed.
In the embodiment that is shown in figure 3, a wide strip 34 of adhesive, which is adhesive on both sides, is applied transversely to the direction of movement of the web 4, which is to say with its axis parallel to the transfer roll 21 (figure 5).
To this end, the slide 25 of the adhesive tape dispenser 22 is supported so as to be moveable transversely across the working width, the axis of the pressure roll 28 and the supply roll 26 extending perpendicularly to the axis of the transfer roll 21.
In order that a sufficiently wide strip 34 of adhesive can be applied to lie flat on the transfer roll 21, the pressure roll 28 is curved concavely in the axial direction on its periphery.
This can be done, for example, by using so-called diabolo rolls.
The pressure roll 28 presses the adhesive tape 24 onto the transfer roll 21--as explained in the previous embodiment--while the slide is moved across the whole working width. Then the pressure roll 28 is lowered, and the adhesive layer of the adhesive tape 24 separates. In order that the application of the adhesive tape onto the transfer roll 21 is effected more rapidly, an adhesive tape dispenser 22 can be arranged on both sides of the machine, and each of these then applies the adhesive strip 34 onto half of the transfer roll 21. The transfer of the adhesive strip 34 onto the web 4 is effected in the manner described heretofore, by pressing the transfer roll 21 onto the web 4.
Figure 6 shows a further embpdiment in which tha double-sided adhesive strip is generated on the transfer roll 1 by spraying.
To this end, beneath the transfer roll 21 there are one or a plurality of glue nozzles 35 that are either arranged across the whole width of the web or else can be moved transversely to the web. Using the nozzles 35, one or a plurality of glue tracks are sprayed onto the transfer roll 21, e.g., of a dispersion adhesive, and these bond to form double-sided adhesive strips.
These are then transferred to the web 4 in the manner described heretofore.
