Definitions

• the pressing is carried out by means of the pressing roller 133, which can be pivoted on both sides in pivotable arms 134, 136 on the guide rails 32, 33 of the ends of the struts 7, 11 facing away from the main slide and can be applied to the supply paper web roll 18 by means of tension springs 137, 138 ( Fig. 1).
• the pressure roller 133 has a jacket made of a plastic with an anti-adhesive behavior, for. B. a jacket made of silicone rubber. Anti-adhesive behavior is to be understood as an adhesive-repellent behavior of the plastic. It is also possible to use a brush roller instead of a pressure roller 133, the bristles of which consist of a plastic with anti-adhesive behavior, so that here too sticking to the top of the double-sided adhesive tape 96 is excluded.
• a second label dispenser 141 on the working carriage 22 (FIG. 4), which has a method of operation analogous to that of the first adhesive label dispenser 66 (FIG. 5).
• the second label dispenser 141 is arranged at the end of the work carriage 22, on the side of the corner cutting device 121 remote from the adhesive tape.
• the labeling device 141 serves z. B. for the output of reflective film labels 139, which are each applied once to the paper web 20 in the vicinity of the cut edge 53.
• Such a label 139 attached to the beginning of the paper web 20 can be used in conjunction with a signal transmitter (not shown) when a paper web roll 18 starts up to select the appropriate point in time for the supply paper web roll 18 to be blended with an ending paper web roll.
• the film label 139 can be arranged both in the vicinity of a first side edge 34 of the paper web 20 and at the same time in the vicinity of the upper part 72 of an adhesive label 67.
• the movement of the label dispenser 141 is triggered by an engagement of a cam analog cam 87 of a driver wheel analog driver wheel 86 (FIG. 5) in a groove 143 of a driver 142 located on the drive cross member 47 (FIG. 3) analog to the first adhesive label dispenser 66.
• the holding device 39; 43, 51; 52, 16 also consist of a frame-fixed vacuum bar that can be commanded by vacuum.
• the cross-member 16 fixed to the frame could be equipped with suction cups for holding the paper web 20 (FIG. 2), the suction air supply being able to take place through the hollow profile of the cross-member 16.
• the adhesive labels 67 it is also possible, after cutting the paper web 20 along the cutting groove 58 in the axis-parallel direction by means of the cross cutting device 61, first to apply adhesive strips 96 on both sides by means of the pressure-sensitive adhesive application device 93, and only subsequently to use the adhesive label dispenser 66, which can also be moved, the adhesive labels 67 to be arranged next to one another at a distance c to apply.
• the double-sided adhesive strip 96 is advantageously at the beginning of the paper web 20, i. H. starting directly at the cutting edge 53 or at a selectable distance d, z. B. applied between one and two millimeters (Fig. 6).
• the adhesive strip 96 can e.g. B. consist of a carrier material strip 96, which is provided on both sides with an adhesive layer. It is also possible to arrange the one arranged on the work slide 22
• pressure-sensitive adhesive application device 93 is to be equipped with clocked spray nozzles which apply sprayable adhesive to paper web 20.
• sprayable adhesive evaporates its solvent after application to the paper web 20 and then remains for a pre-adjustable period of time, e.g. B. ready to stick for a day or two.
• the shape of the spray-applied adhesive 96 can be in the form of strips, wavy lines or zigzags.
