The method for preparing a feed roll of paper for flying roll change comprises passing the excess leading edge (51) under a cross-bar (13). An applicator (30) is then moved across the roll to apply double sided adhesive tape to the roll. A cutter blade (41) is then turned into a cutting position and the applicator is again moved across the roll to trim off the excess paper. An Independent claim is included for a machine for carrying out the method.

Description

The invention relates to methods and a device for preparing a roll of stock paper for the flying reel change according to the patent claims 1, 2 and 4.

A flying roll change is understood to mean automatic gluing a new supply paper web roll to the paper web of an almost expired one Roll in the roll changer of a web-fed rotary printing press. To make this possible a new roll of stock paper web must be prepared accordingly. The Outer layers of the roll damaged during transport must be removed and the paper web beginning of the outermost layer must be attached to the second layer be so the new role in accelerating to speed the unwinding paper web does not unwind. Furthermore, a connection adhesive be provided at the start of paper at full production speed the new paper roll with the paper web of the almost empty roll safely combines. After sticking on the new roll of stock paper, it comes off at the beginning of unwinding you - at the second layer - held the beginning of the web by the provided predetermined breaking points tear and the old web is behind the connection point cut or chipped off by a device on the reel changer.

Various systems are known for preparing supply paper web rolls, such as so-called V or W adhesive tips, which the V or. Hold the W-shaped path start at the point or points on the roll or straight adhesive that is perpendicular or up to about 70 ° to the direction of the paper web are arranged. All procedures are done manually or automatically with liquid Glue or done with double-sided tape.

DE 41 18 690 describes a straight adhesive system with double-acting ones Adhesive tapes for the holding and connecting adhesive known, in which releasing the beginning of the web from the second layer by means of a perforation line is made possible.

EP 771 300 shows an apparatus and a method for the preparation of a Watched out stock roll for the flying roll change. To a height-adjustable frame is arranged on the reel changer on which in Move a work carriage in the direction parallel to the supply paper web roll lets and a holding device for the beginning of the web unwound from the roll. On the work slide are facilities for cross cutting the paper web, for applying adhesive labels and for applying a double-sided Adhesive tape arranged for connection to the running paper web. In the facilities for applying the glue are next to the unwinding rolls for the adhesive tapes also take-up rolls for receiving the Carrier tapes provided. The method to be carried out with the device enables the cross cutting of the paper web, the application of the adhesive labels and the double-sided adhesive tape during a linear axis parallel Carrying out movement of the work sled also provides for the different ones Functions in different orders one after the other - each with a linear back and forth movement - of the work carriage. To Completion of the necessary outward and return movements is the beginning of the path from released from the holding device and wound back onto the supply paper roll, with a pressure roller - the protruding beyond the beginning of the web Adhesive labels - on the second layer of the paper roll to hold the start of the web presses.

However, double-sided adhesive tapes have recently become known, whose - the start of the web on the second layer of the stock paper roll holding - split up adhesive layers. Such tapes require others Methods and apparatus for preparing a roll of stock paper web the flying role change.

6 shows the cross section of a double-sided adhesive tape (80) which has become known from DE 196 28 317. The cutting plane of the adhesive tape (80) is transverse to the unwinding direction of a corresponding adhesive tape roll. In the rolling direction, the outside is provided with a protective or separating layer (81) divided by a slot (82), which covers the adhesive (83) applied to a carrier material (84). On the inside of the adhesive tape (80), another strip that does not cover the entire width is covered with an adhesive (85) in the unwinding direction. On this adhesive (85) adheres a splicing carrier layer (84) to which an adhesive (87) is also applied. In the case of adhesive tapes (80) made up into rolls, the additional protective or separating layer (88) can be omitted because the adhesive layer (87) lies on the outside of the protective / separating tape (81).
7 shows the second paper layer (55) of a supply paper roll (50) on which an adhesive tape (80) is fastened by means of the adhesive (87). The unwinding axis of this supply paper web roll (50) runs into or out of the image plane. The beginning of the paper web (53) is held on the outside of the adhesive tape (80) in the area of the protective / separating tape (81a) by the adhesive (83). The remaining outer strip width of the adhesive (83) is already freed from the protective tape (81b) in this illustration and sticks to the empty paper web (54) according to FIG. 8. FIG. 8 is the enlarged section Z from FIG. 5, which shows a flying reel change in a reel changer (60). Immediately after the paper web (54) has been glued, the splicing carrier (86) is split into two parts (86a and 86b) so that the beginning of the paper web (53) - pulled by the idling paper web (54) - by the new supply paper web roll (50) can be unwound. The empty paper web (54) is cut off after the bond point and a new stock paper web roll (50) can be installed in the roll changer (60) for the empty paper roll (50 ').

From DE 195 44 010 an adhesive tape is known, which also according to The principle described above works. In contrast to the one described above The inside of the adhesive tape is completely coated with an adhesive so that it is over its entire width on the second layer of a supply paper roll liable. Another advantage of these tapes is the integration a reflection or metallic layer in the carrier layer, whereby it is possible to interrogate optical or inductive signals, for example to clean waste paper to activate. The use of such tapes saves you Effort to apply additional signal foils.

Another variant of such adhesive tapes is described in DE 198 30 673. Such an adhesive tape (90) is shown in FIG. 9 analogously to FIG. 6. The adhesive (92) on the outside is replaced by an undivided Protective tape (91) covered and the carrier (93) is on its underside or the inside of the adhesive tape (90) over the entire width with an adhesive (94) coated. A portion of the adhesive (94) is in the unwinding direction Partial stripes coated with a splicing carrier (95) on its other Surface has a further adhesive layer (96). When deploying a such adhesive tape (90) on a roll is this adhesive (96) and the Adhesive (94) on the outer separating layer (91) of the layer below and the protective / separating layer (97) can be omitted. The attachment of the beginning of the paper web (53) on the second paper layer (55) of the supply roll (50) is shown in Fig. 10 shown. With - on the second paper layer (55) - the beginning of the paper web (53) the adhesive tape strip (90) with the one adhesive (94) glued the beginning of the paper web (53), the easy-to-splice backing layer (95) survives and with its adhesive (96) a connection to the second paper layer (55) produces. The outer separating band (91) has already been pulled off in this illustration, so that the adhesive (92) for the connection adhesive is exposed. 11 shows the section Z from FIG. 5 when using an adhesive tape (90) according to 9 and 10. Analogously to the other examples, the easy-to-splice splits Carrier (95) in two parts (95a and 95b) so that the beginning of the paper web (53) can be unwound from the new roll of stock paper. Advantageous with this The type is that the paper web start (53) when applying the adhesive tape (90) not hit back and then pushed back onto the outside got to. If the method of operation is inaccurate, however, there is a risk that the adhesive strip (90) protrudes too far beyond the beginning of the paper web (53), the adhesive (94) adheres to the second paper layer (55) and the release of the beginning of the paper web (53) after sticking to the idling paper web (54) prevented.

When processed appropriately, the adhesive tapes have such an active principle a high level of adhesive security and simplify the preparation of rolls of stock paper for the flying reel change.

The object of the invention is an adhesive tape applicator and an executable therewith Process to create manual or automatic glue preparation of stock paper web rolls with splitting adhesive tapes and to simplify the previously known devices and methods.

This object is solved by the features of claims 1, 2 and 4.

The application device according to the invention can advantageously be both stationary can be used on a roll changer as well as a mobile device for adhesive preparation of not yet reworked stock paper web rolls become. Likewise, an advantageous use of an application device according to the invention directly after a paper unpacking station in a stationary portal construction possible as manual, semi-automatic or fully automatic version. When used on the reel changer, the protective tape can be used for the adhesive connection pull off immediately. For example, a larger number of rolls of stock paper delivered - after unpacking and removing the damaged layers of paper - to prepare, the applicator can be on a cart to the Approach the respective supply roll and carry out the method according to the invention. Since the usage date is usually still open for such roles, it will Leave the protective tape on the area provided for the bond and cut off by a cutter at the end of the order. The so prepared Rolls can be kept in a paper warehouse and even after days the connection adhesive still has its full adhesive force to ensure a secure to ensure flying reel changes. The protective strip can either removed manually or, if necessary, by an automatic device on the reel changer be replaced.

A device according to the invention allows in addition to the above-described self-adhesive tapes, of course also the processing of other adhesive tapes that work on the same or a similar principle.

FIG. 1 shows a device according to the invention, which acts as a mobile device is carried out, from the side, on a roll of stock paper web to be prepared (50) arranged. The stock paper roll (50) is on a conventional one Transport system for such paper rolls stored and to illustrate the Possible uses of the device are within the roll of stock paper (50) other smaller roll diameters are shown. For the explanation below 1, view X - shown in FIG. 2 - is also to be included.

The mobile device consists of a trolley (1) with four steerable and lockable Wheels (3) that have ideal mobility as well as exact positioning and fixation enable the device with respect to a supply paper roll (50). The Frame (2) is open on the front broadside, so that with the carriage (1) can be moved close to the stock paper roll (50) that a - the transverse unit (13) belonging to the linear unit (10) on the surface of the supply paper web roll (50) rests. The linear unit (10) consists essentially from a carrier (18) on which a guide rail (11) and grooves are provided are and the crossbar (13), which at both ends with side plates (14) completes. The side plates (14) are each via two clamping devices (19) attached to frames (4) of the carriage (1) and can be Set up the height. Each side plate (14) is with the two clamping devices (19) via spindle nuts in a - each mounted on the frame (4) - Threaded spindle (5) guided. The threaded spindles (5) can be on both racks (4) of the carriage (1) each by hand wheels (6) independently of each other turn, which causes the height of the linear unit when the clamping devices (19) are released (10) can be adjusted. The clamping devices (19) are activated so that the side plates (14) of the linear unit (10) either directly or brace with spacers with the frames (4) and rigidly on the carriage (1) are fixed. Due to the height adjustment of the linear unit (10) can be Devices according to the invention supply paper web rolls (50) of various types Diameter, for example from about 700 to about 1300 millimeters, for the flying one Be prepared to change roles.

The linear unit (10) is preferably parallel to the unwinding axis of the supply paper web roll (50) set up, but because of the adjustment on both sides on the frames (4), the linear unit (10) can also be inclined to the paper roll axis adjust, then usually set an inclination up to about 20 ° becomes. For inclinations, either joints and sliding elements must be provided are used or the elasticity of the corresponding components become.

In a fully automatic variant, the threaded spindles (5) driven by controllable electric motors and for clamping the side plates For example, electromagnets can be provided. Of course can also be used to adjust the height and fix the linear unit (10) other operating principles, such as pneumatic cylinders, are provided.

As can be seen in principle from FIG. 2, one can on the linear unit (10) to the other end of the stock paper roll (50) over its surface an application device (30) can be moved away. The length of the linear unit (10) is therefore preferably dimensioned so that the applicator (30) both ends the paper roll (50) can overflow with its entire width. If folding devices are provided, which allow the application device (30) of the To fold away the surface of the paper roll (50), it is also possible to use supply paper web rolls (50) to be processed with widths that are almost the length of the linear unit (10) correspond. Stops (12, 12 ') are provided on the linear unit (10) that for the applicator (30) the beginning and end of the tape application mark. The stops (12, 12 ') can also be so with elbows (21) be connected, which abut on both end faces of the supply paper web roll (50), that together with the adjustment to different roll widths are automatically added and the beginning and end of the adhesive always Right.

Fig. 3 shows the section A-B of Fig. 2 enlarged, the side plate (14) is assumed to be transparent and the view of what is arranged behind it Releases application device (30). On the side plate (14) there are holding bores (20, 20 ') is provided, through which the clamping device (19) supports the bracing the frame (4) of the carriage (1). The lower holding hole (20 ') is as Elongated hole so that the applicator (30) with the linear unit (10) around the upper holding hole (20) - parallel to the axis of the supply paper web roll (50) - pivoted and with - on the paper roll surface lying crossbar (13) - be aligned radially on the axis of the stock paper web roll (50) can. This ensures that regardless of the roll diameter Height of the linear unit is set up, the application roller (39) and the sliders (38) work evenly on the respective paper surface. For checking the correct radial alignment is an alignment mark on an elbow (21) (15) provided, which are at the level of the paper surface or slightly below should.

The elongated holes can be used to expand the swivel range of the side plates (14) (20 ') or, for example, additionally the upper holding bores (20) are each designed as an elongated hole.

It is preferred in the grooves of the carrier (18) on both end faces of the roll of supply paper web (50) each an elbow (21) created and with corresponding Nut nuts attached. There is a tensioning device on each of the angle pieces (21) (16) arranged with the linear unit (10) if necessary additionally can be clamped against the paper surface. As from Figures 1 and 2 can be seen, is in both openings of the single-axis hole (52) Stock paper roll (50) introduced a bundle box (7) to the projecting At the end of each strap (17) looped and through the tensioning device (16) can be cocked. Appropriate brackets are on the carriage (1) provided for such collar bushings (7) which are specially designed for those who do not have them Roles can be used.

Sheets (23), preferably made of spring steel, can be attached to the angle pieces (21). are provided which extend to the side of the stock paper web roll (50) and with a notch - about as wide as the application roll (39) - a short piece reach into the paper surface. By supporting the sheets (23) on the Cross-beam (13) becomes the second paper layer (55) at the beginning and end of the tape application held down, so that advantageously a lateral warping of the paper can be prevented if too much sideways when applying the adhesive tape Train acts on the paper.

A guide rail (11) is also provided on the carrier (18), in which the applicator device (30) is guided on its base body (31) with corresponding means without play and can optionally be moved and positioned in a path-controlled manner by suitable drive units.
In particular for manual operation, stops (12, 12 ') can be positioned on the top of the carrier (18), which block the path of the application device (30) at the beginning and at the end of the application of the adhesive tape. These stops (12, 12 ') must be disengaged manually in the working direction; on the way back they are automatically overrun by a run-up slope.

In the view according to FIG. 3, an adhesive tape roll (45) is also shown which is on a rotatably mounted, preferably braked bracket (35) for unwinding the adhesive tape is arranged. For winding up the protective tape, which the adhesive layers of the double-sided adhesive tape against each other separates and protects after application to the paper surface is another Bracket (36) is provided, on the circumference of which the protective tape - the beginning preferably held by a slotted clamping ring (43) - can be wound up. Both brackets (35, 36) and also an application unit (37) are on one - arranged opposite the base body (31) - movable sliding piece (32).

On the application unit (37) an application roller (39) is rotatably mounted, which the Press tape on the paper surface. The contact surface of this job role (39) is excluded in the middle area, so that the adhesive tape (80, 90) only presses with their two outer areas and the application of adhesive tape (80, 90) on stock paper web rolls (50) with different diameters is possible. When rolling on the adhesive tape, the application roller drives (39) via a belt drive (42) - by a freewheel against reverse running locked - bracket (36) such that the protective / separating tape (81, 91) - as Partially wide strip (81a) or in its entire width (81, 91) - under tension is wound up. The belt driven bracket (36) and bracket (35) for the adhesive tape are, for example, rollers on which the waste tape is located wind up or put on a roll of tape, and are preferred equipped with adjustable brake springs. To the side of the application roller (39) Sliders (38) are arranged, which are resiliently supported on the application unit (37) and so hold the paper down to the side of the adhesive strip (80, 90). The sliders (38) are preferably made of polytetrafluoroethylene. In the illustration the sliding piece (32) is in a position for applying the adhesive tape (80, 90). Through an eccentric - rotatably mounted in the base body (31) (34) which is provided with a hand lever and its eccentricity in one Engages recess of the sliding piece (32), the sliding piece (32) move. The hand lever can be operated in this manually operated version of the eccentric (34) preferably in the order and a return transport position snap to these predetermined positions for the corresponding To record functions.

At the end of the adhesive, the position of the applicator (30) is determined by a clamping screw or a pneumatic cylinder is fixed on the linear unit (10) and the sliding piece (32) in the return transport position, whereby the application roll (39) lifts off the paper surface and the cutting knife (40) shown in FIG. 4 can be used to cut the adhesive tape (80, 90) between the lifted application roll (39) and the paper surface. The cutting knife For this purpose (40) is preferably pivotally suspended on a lever parallelogram and a resiliently displaceable sliding plate (29) is arranged on its underside. It is advantageous to have the cutting knife (40) in the order position swivel in so far that the adhesive-repellent slide plate (29) the adhesive tape (80, 90) presses on the paper surface and when switching to the return position continue to pivot the cutting knife (40) so that the slide plate (29) constantly exerts pressure on the adhesive tape (80, 90). When swiveling further the sliding plate (29) moves and thus gives the cutting edge of the cutting knife (40) free, which then cuts off the adhesive tape (80, 90).

When using so-called strapless adhesive tapes, the adhesive consists itself no connection, so that such tapes - provided the protective / separating tape is completely removed - simply by lifting the Tear off application roll (39) automatically. In these cases, the cutting knife (40, Fig. 4) can only be retracted if the protective strip (81b, 91) on the Adhesive (83, 92) is left to a supply paper roll (50) for the prepare for later use.

In the return position, as can be seen in FIG. 3, a paper cutting knife can be used (41) swivel into a longitudinal slot on the crossbar (13) and when the applicator (30) moves back into its starting position becomes the excess roll start, which is pushed back over the crossbeam (13) (51) cut off. The resulting predetermined paper web start (53) has exactly on the paper roll from the contact line of the crossbar (13) the length that he only the intended when pressed on the adhesive Area covered. The paper cutting knife (41) is preferably with several Provide cut edges and reversibly arranged on its swiveling holder, to quickly and easily when a cutting edge is worn to be able to bring an unused cutting edge into the cutting position.

The kicked-back roll start (51) is preferably over the whole Roll width of a hold-down device (22) around the crossbar (13) underneath Tension held. With the preferably angular hold-down device (22) the beginning of the paper web (53) advantageously evenly on the adhesive the adhesive tape (80, 90) are pressed.

For a fully automatic version, the application device (30) can be switched over between the different positions, preferably with pneumatic cylinders equipped, which drive against appropriate stops. Other suitable Drives are of course also possible.

FIG. 4 shows the application device 30 according to the invention from FIG. 1 in view Y as an enlarged detail. Behind the application device (30), the carrier (18) runs with the guide rail (11) on which the base body (31) is guided with four guide rollers without play for movement over the surface of the supply paper web roll (50). On the front of the base body (31), which is preferably shaped as a flat base plate, two guides (33) are arranged, between which the sliding piece (32) is movable transversely to the axis of the supply paper web roll (50) and from the eccentric (34, Fig. 3) can be placed in the various working positions. On the sliding piece (32), which is preferably designed as a plate, is - in this view in the upper area - the holder (35) for unwinding an adhesive tape roll (45) and - in the lower area - the driven holder (36) for winding up the protective / separating tape arranged. Different receptacles for different inner diameters of the adhesive tape rolls (45) can be attached to the unwinding holder (35). The winding bracket (36) is preferably provided with a drum onto which a slotted tension ring (43) for tensioning the beginning of the tape of the protective / separating film (81, 91) is pushed. When using adhesive tapes with divided protective / separating tape, both strips can be wound up parallel to one another or only one of them. A separate independent drive, for example an electric motor, can also be provided for this holder (36).
A braking torque can be set on both brackets (35, 36) to influence the respective belt tension. Disks are preferably provided on the brackets (35, 36) against which the strips can rest in the axial direction. The freewheel on the take-up bracket (36), which is locked against reverse, prevents the protective tape (81, 91) from unwinding when the applicator roll (39) is lifted off.

At the end of the sliding piece facing the supply paper web roll (50) (32) there is an application unit (37) in which the application roller (39) is rotatably mounted and on which - in the application and cutting position - sliding pieces (38) Support resiliently to hold the paper down on the side of the adhesive tape. A movable guide roller (47) is also on the slide pieces (38). and a cutting knife (40). The cutting knife (40) is for cutting the protective / separating tape (81, 91) and / or the adhesive tape (80, 90) provided and can be operated via a hand lever not numbered. In a automatic version is preferably a pneumatic cylinder instead of a hand lever intended. The operating mechanisms are self-evident so coupled with the cutting knife (40) that they the resilient mobility of Do not hinder sliding pieces (38). In the illustrated order position of the sliding piece (32) is the cutting knife (40) from the area of the application roller (39) moved out. In both versions (manual or automatic) it will Cutting knife (40) held in this starting position by spring force Avoid damage or malfunctions.

The tape (80, 90) is from the tape roll (45) - with that through the Separating tape (81, 91) protected side - via a first guide roller (44) to one another guide roller (46) and from there - through the in the sliders (38) stored - adhesive-repellent guide roller (47) with its protected Side resiliently applied to the application roller (39). Up to the line of contact of the application roll (39) with the surface of the stock paper roll (50) where it has the tape (80, 90) to glue its inside to the paper surface, the adhesive tape (80, 90) from the protective / separating tape (81, 91) - which loops around the application roll (39) - held on the outer surface. The Wrapping a partial strip (81a) or the entire width of the protective / separating tape (81, 91) around the application roller (39), is by the guide roller (48) ensures which the protective / separating tape (81, 91) for the take-up holder (36) leads.

Can between the first guide roller (44) and the second guide roller (46) a swivel lever (49) can be provided which, when the Sliding piece (32) in the return position, for example by a cam, is pivoted into the path of the adhesive tape (80, 90). This path extension for the adhesive tape (80, 90) between the two guide rollers (44, 46) is compensated for by unwinding from the tape roll (45). At the Switching the application device (30) into the order position pivots the swivel lever (49) back to its original position, outside of the course of the tape and the excess length of the adhesive tape (80, 90) thus freed facilitates in an advantageous manner Way to start the adhesive application, since the tape (80, 90) is at the beginning is not under tension.

Fig. 5 shows the schematic structure of a reel changer (60) during a roll change at the moment the new stock paper roll is glued on (50). The - accelerated to the speed of the paper web (54) new stock paper web roll (50) is turned on by swiveling the take-up arm the idling paper web (54) is created so that the input - with reference to Fig. 8 and 11 - explained splicing processes.

The adhesive tapes (80, 90) shown in FIGS. 6 and 11 or other such working tapes are usually about 50 millimeters wide and with the cross-sections shown on cardboard rings with inner diameters of about 76 millimeters wound. The rolls assembled in this way have an outer diameter about 150 millimeters, an adhesive tape length of about 50 Meters. The device described can also be easily rolled up set up with different dimensions. The outer adhesives (83, 92) of the Adhesive tapes (80, 90) with protective or separating tapes (81, 91) are common Silicone layers - covered, which are also slotted with some types of adhesive and therefore can be removed separately. The inside of the Adhesive tapes each lie on the separating layer of the roll layer underneath on.

To prepare an unwrapped roll of stock paper web that has been freed from damaged layers (50) for a flying reel change, the carriage (1) with the linear unit (10) set to the appropriate height and fixed by blocking the wheels (3). After creating the contra-angles (21) on the end faces of the stock paper roll (50) and setting the correct inclination using the alignment marks (15) can be used for better stabilization additionally the tensioning straps (17) are put on. For identification the beginning and the end of the stops (12, 12 ') on the Carrier (18) of the linear unit positioned accordingly. To simplify the stops (12, 12 ') with the elbows (21), so that with them Apply to the front of the stock paper roll (50) at the same time Stops (12, 12 ') are correctly positioned. The elbows (21) are preferred on the sides facing the roller (50) with bevels, so that when preparing several rolls of stock paper of the same width (50) based on the first and the following roles (50) can be used for precise positioning without the end faces or damage outer layers of paper. Can hold down the paper the sheets (23) are placed on the end face of the supply paper web roll (50).

With the fully automatic device, the tasks of Stops (12, 12 ') and the other positioning aids by photoelectric Sensors or other electronic devices taken over.

The applicator (30) is in its initial position, preferably laterally Stock paper roll (50) and is with a corresponding tape roll (45) stocked. Depending on the intended use, the protective / separating tape (81, 91) either as a partial strip (81a) or in its entire width (81, 91) or- at Use of the adhesive tape (90), as shown in FIG. 9 - not at all for Threaded onto the holder (36).

Before the glue application can begin, the roll start (51) is over the Crossbeam (13) pushed back, the excess roll start (51) must be so long that it is possible to start the defined paper path (53) on Cut the longitudinal slot of the crossbar (13). The beginning of the roll (51) can held under tension by a hold-down device (22) around the crossbar (13) become.

Then the applicator (30) up to the first stop (12), the start of gluing marks, pushed and placed in the tape application position. The stop (12) is released and when the applicator (30) is pushed further until the next stop (12 ') - the adhesive end - the adhesive tape with its Applied on the inside to the second paper layer (55) of the supply paper roll (50). There the application device (30) is placed in the return transport position and if necessary, use the cutting knife (40) to make the protective / separating tape and / or cut off the adhesive tape. After that, the sheets (23) can be removed if necessary and the paper cutting knife (41) is in the longitudinal slot on the Crossbar (13) rotated in order to move the applicator (30) back cut off the excess roll start (51) from the stock paper roll (50). The longitudinal slot is positioned so that the predetermined cut there Paper web start (53) when finally striking back to the second paper layer (55) falls exactly on the adhesive area intended for it and can be pressed. The hold-down device can advantageously be pressed on (22) can be used, which is preferably designed as an angle profile Form press the corresponding paper area evenly.

Before preparing the next roll of stock paper web (50) you need the paper cutter (41) turned out of the cutting position and if necessary the straps are loosened.

This method described above is used in the processing of adhesive tape 6, 7 or this tape, which in principle is similar.

When using the adhesive tape (90) according to Fig. 9, 10 or the same Principle of functioning adhesive tapes, the applicator (30) must first in the position for cutting the beginning of the paper web (53) is set, the paper cutting knife (41) rotated to its paper cutting position and the predetermined one Cut the beginning of the paper web (53). The predetermined web start (53) is then pushed back onto the second paper layer (55) of the supply paper roll (50) and the adhesive tape (90) is applied by the application device (30) in such a way that the free adhesive (94) ends exactly at the beginning of the paper web (53) and the adhesive (96) on the carrier (95) which is easy to splice the second paper layer (55) sticks. This can also be done by threading or not threading the protective / separating tape (91) are fixed on the holder (36), whether it is peeled off directly or should remain on the adhesive (92). At the The protective / separating tape (91) and / or the adhesive tape can end the adhesive application (90) can be cut off.

The adhesive tape (80, 90) is preferably not flush from one end of the Stock paper roll (50) applied to the other, but somewhat from the edge spaced apart, the tape application is started and a short distance in front the other edge it is ended. This has the advantage of being slightly sideways offset running web compared to the new stock paper web roll (50) after the flying roll change, no adhesive remains uncovered.

So as not to set a working direction when applying the adhesive tape application devices (30) can be provided, which are mirror images in the working direction are built up to each other. The use of an appropriate application device (30) can be operated manually with the right or left hand simplify.

12 shows a reel changer (60) on which the application device (30) with its guide parts described according to the previous figures is arranged between two pivot arms (61). After preparing the Ingested stock paper web roll (50), the swivel arms (61) in one Starting position - outside the work area of the reel changer (60) - be pivoted.

Figures 13, 14 and 15 show preparation stations (65, 67, 68) which for non-approved supply paper web rolls (50) are provided and preferably be placed near an unpacking station. The preparation station shown in Fig. 13 (65) is carried out in portal construction and the guide parts of the Applicator (30) are arranged between lifting and lowering supports (66).

The preparation stations (67, 68) according to FIGS. 14 and 15 are each with Swivel arms (61) - as described for Fig. 12 - equipped and once in Stand construction (67) as well as a ceiling construction (68).

All of these variants can be operated manually, partially or fully automatically his.

In the case of a fully automatic version, the crossbar with the application device automatically lowered by the swivel arms (61) until they are on the paper roll (50) rests. The beginning of the roll on the paper roll (50) hangs in a predetermined Distance under the traverse and is automatically added by another Traverse pneumatically sucked in. The beginning of the role recorded in this way Swiveling this crossbar back over the cutting bar wound and tensioned. After creating the beginning of the paper web and applying the adhesive tape the swivel arms (61) are swiveled back into their starting position. A sheet metal plate can be used to dispose of the cut roll start be arranged, via which the roll start in a waste container to be led. To do this, the start of the roll is unwound from the traverse and that Vacuum switched off, so that the excess roll start on the oblique arranged sheet metal plate falls.

On a semi-automatic version, the device must be operated by pressing a button lowered onto the paper roll and the beginning of the roll manually via the cutting bar be placed. By activating a suction bar, the beginning of the roll is over the cutting bar tensioned and running by starting the applicator automatic tape application.

For the linear movement of the applicator parallel to the axis of the paper roll a toothed belt can be provided between the two ends of the Linear guide rotates and is connected to the applicator. As a drive for the toothed belt can be provided with a correspondingly controlled electric motor become.

It can be particularly advantageous, also for the adhesive tape and the application rolls to provide a drive, whereby a slip and friction-free tape application is possible. This can be done on the linear guide or on the crossbar a rack can be arranged with which a - rotatable on the applicator stored - gear cooperates and the linear movement of the applicator translates into a rotary motion. The gear is switchable Coupling - preferably an electronically controllable magnetic coupling - with a drive pulley (100: Fig. 4a) coupled. As is apparent from Fig. 4a, the drive pulley (100) is wrapped in a toothed belt (101), which is about further pulleys (103, 105, 106) and over pulleys (102, 104) again back to the drive pulley (100). On the shaft of a pulley (106) a further pulley is arranged, which over a another belt drive (42) drives the application roller (39). Both sides of the application roll (39) arranged slide pieces (38) can be particularly advantageous Can be adjusted to the paper web roll by pneumatic cylinders, whereby there is an advantageous constant in each stroke position of the applicator Contact pressure results. When applying the adhesive tape, the application roll adapts (39) and the sliders (38) by appropriate lifting movements to the Paper surface. The pulley moves during these lifting movements (106) and the pulley (104) with up or down, while the others The belt pulleys (100, 103, 105) and the deflection roller (102) remain stationary. Thereby the wrap length of the toothed belt (101) remains with each stroke same and the transmission of the drive torque is always guaranteed.

So that the application unit aligns itself with the axis of the paper web roll can and the tape is pressed evenly across its width, can the applicator (30) about an axis of rotation parallel to the paper roll axis be rotatably supported. For adaptation to the surface of the paper web roll a few degrees of rotation are sufficient. The applicator (30) can be held resiliently in a central position.

The toothed belt-driven holder (36) for the paper roll and the holder for the tape roll are with adjustable brakes - preferably on the front employed disc springs - equipped. On the bracket (36) an additional additional brake - for example a pneumatically acting brake - provided become. This can prevent the tape from being lifted off from a paper web roll and when reinserting it onto another paper web roll on the application roller (39) is withdrawn.

To actuate the cutting knife (40) to cut off the applied A so-called multi-position cylinder (107) can be provided on the adhesive tape. This can be controlled so that it depends on the cutting knife (40) Requirement in a rest position or in a pre-positioning - with on the tape overlying slide plate (29) - and can provide a working stroke for cutting the tape can run. Even with the fully or semi-automatic The adhesive tape can be designed with or without a protective layer to be applied on paper web rolls. In contact with the adhesive surfaces upcoming pulleys are preferably made of adhesive-repellent Made of materials.
