- the knife-like ground edge of the gripper plate 28 hooks onto the uppermost paper web of the winding roller 8.
- a paper loop 32 is formed, as shown in FIG 26 is held.
- the entire gripping device 25 is raised by the working means 27, whereby the paper web start 30 is lifted off the winding roll 8; Fig. 6.
- the winding roll 8 shown in FIG. 4 is rotated clockwise by the roll 26 and / or a device not shown in the drawing.
- the gripping device 25 is lowered over the swivel arm 103 by the working means 27 onto the surface of the winding roll 8.
- the rollers 26 are pressed onto the surface 65 of the winding roller 8 and rotate at the same peripheral speed as this.
- the gripper plate 28, which is fastened to leaf springs 110, is lowered by the lifting device 29 onto the surface of the winding roll 8.
- the gripper plate 28, which on the front side a knife-like cut 28a, such as. B. has a serrated knife or a knife with a smooth cut, hooks with the top layer 65 of the web. It is advantageous that the pressure with which the gripper plate 28 is pressed onto the web is dosed as precisely as possible to ensure that on the one hand this pressure is high enough so that the gripper plate 28 hooks securely onto the top layer 65 of the web , and that, on the other hand, the pressure is not too high so that the web is not cut or damaged.
- the pressure can e.g. by the manner in which the leaf springs 110 are dimensioned and the angle at which they impinge on the material web.
- the top layer 65 of the web is held back by the gripper plate 28, and after the winding roll 8 rotates in the direction of the arrow one Web loop 32 between the rollers 26 resting on the top web 65 and the gripper plate 28a.
- FIG. 6 shows that the gripper plate 28 is now raised again by the lifting device 29.
- the web loop 32 is held between the upper part 9b of the gripper plate 28 and the end faces 116 of the recesses 117 of the rollers 26, as shown in FIG. 7.
- the gripping device 25 is now lifted from the surface of the winding roll 8 by the working means 27 via the heavy arm 103 and the beginning 30 of the material web is thereby pulled off the winding roll 8.
- the web of material can now be fed to one or more further processes or processing steps, for example in order to be cut in a station and provided with an adhesive tape. It is also possible for the web to be unwound from the winding roll by a web tension device in order, for example, to subsequently print it or to process it in another way. It is also possible for the web loop 32 to be released again by lowering the gripper plate 28 in order to position the start 30 of the web at a desired location.
- the gripping device 25 can also be guided along the circumference of the winding roll 8 while it is being moved or stopped, in order to produce the web loop 32 desired for picking up the web start 30.
- FIG. 7 shows a plan view of the rollers 26 shown in FIGS. 4 to 6 with the gripper plate 28 engaging therein.
- the web loop 32 is between the knife-like ground front 28a of the gripper plate 28 and the rollers 26 or the end faces 116 and recesses 117 of the rollers 26 so that the web 30 can be lifted off the winding roller 8. If the upper web 65 held in this way is raised by the gripping device 25 to such an extent that it has been guided past the drive roller 10 and the belt system 20 to 23, as shown in FIG. 8, the roller 10 can be moved in the direction of the rollers 35 and / or the rollers 35 can be moved to the roller 10 until the roller 10 and the rollers 35 touch each other over the intermediate web start 30.
- the web start 30 is thus clamped between the roller 10 and the rollers 35 and, after the gripper device 25 has been opened, for example by extending the gripper plate 28, can be pushed into the belt system 20 to 23 by a finger plate 36, so that the web start 30 of this Belt system 20 to 23 can be transported further.
- the roller 10 can now be stopped together with the winding roller 8. Now the work slide 43, which is guided by the rollers 41, 42 on the rail 40, e.g. are guided in the longitudinal direction past the winding roll 8. With appropriate means, the adhesive tape 44 with the adhesive surface 62 can be glued onto the outer surface of the winding roll 8 and the cover tape 64 can be pulled off the adhesive tape 44 at the same time. Since in this process the paper web to which the adhesive tape 44 is adhered is still wound on the winding roll 8, the web does not need to be additionally held.
- FIG. 9 shows a device for applying the adhesive tape 44 with a working carriage 43, which is displaceably mounted on a rail 40 by means of guide rollers 41, 42 and can be moved by a drive 204.
- a reel spool 205 with the double-sided adhesive tape 44 and the cover tape 64 is arranged on the work slide 43.
- the adhesive tape 44 is coated on the side covered by the cover tape 64 over the entire width and on the opposite side only in an area 62 which, for example, makes up about a quarter of the tape width, with adhesive 63, as described above with reference to FIG. 2.1.
- the guide rollers 208 and 209, as well as the pull roller 210 can be provided with corresponding recesses in the area of the adhesive 62, so that no adhesive can settle on these rollers.
- the adhesive tape 44 is guided together with the cover tape 64 around the guide roller 208 to the pull rollers 210 and 211 and from there onto the separating or deflecting roller 212.
- the two tapes 44 and 64 are separated on the deflecting roller 212.
- the cover tape 64 is passed around the roller 216, which is located on the lever 213, which is connected to the working medium 215 or e.g. biased by a spring (not shown) about pivot 214 as shown by the broken lines. Then the shroud 64 is guided over the pressure roller 219 mounted on the lever 217, pivotable about the pivot point 218.
- the adhesive tape 44 is guided from the deflection roller 212 through the cutting device 220, 221, via the guide roller 209, also via the pressure roller 219, so that the adhesive tape 44 and the cover tape 64 are reunited on the pressure roller 219.
- the adhesive tape "44 is now adhered to the object to be loaded, such as the lower layer 66 of a paper roll 8, when the pressure roller 219 with the associated drive means 222 is lowered onto it. During this process, the cover tape 64 is wound onto the spool 224 ,
- the sensors 225 and 226 are used to scan the position and the size of the object 66.
- the object to be equipped with adhesive tape 44 such as, for example, the layer 66, is brought into position in the region of the working carriage 43.
- objects of different sizes can also be equipped with adhesive tape 44 or another tape-like material by the device described.
- the working carriage 43 moves from its starting position in FIG. 9 from right to left over the object 66.
- the sensors 225 and 226 recognize the position and size of the object 66 and a corresponding program is activated.
- the work carriage 43 moves to the position at which the beginning of the adhesive tape 44 is to be glued to the object 66. Now the pressure roller 219 is lowered with the adhesive tape 44 onto the object 66 to be loaded.
- the work carriage 43 starts moving again.
- the reel spool 205, the pull rollers 210, 211 and the pressure roller 219 are preferably driven synchronously with the slide movement, so that the adhesive tape 44 is adhered to the object 66.
- the excess shroud 64 is wound onto the spool 224.
- the carriage 43, the unwinding reel 205 and the pulling rollers 210 and 211 are stopped.
- the cutting device 220, 221 is actuated.
- the adhesive tape 44 is cut to the required length.
- the carriage 43 starts moving again and the rest of the adhesive tape 44 is applied to the object 66 to be fitted. Since the unwind spool 205 and the tension rollers 210 and 211 remain blocked during this process, the roller 216 is pivoted about the pivot point 214 toward the pressure roller 219 so that the cover tape 207 can be pulled off continuously and under tension, as shown in FIG. 10.
- the pressure roller 219 with the drive means 222 is lifted off the object 66.
- the swivel roller 215 is swiveled back into its original position.
- the cover tape 64 is unwound from the spool 224.
- the adhesive tape 44 is pushed back into the starting position on the roll 219 by rotating the unwind spool 205 and the pull rolls 210 and 211.
- the carriage 43 moves back to its starting position and a new cycle can begin.
- the adhesive tape 44 can be applied to the object 66 not only in one piece, but with one or more interruptions and with a pre-selectable distance.
- the adhesive tape 44 can be cut to the desired length. Another gluing process can then be carried out at the desired position.
- the application device can be arranged stationary and the object 66 to be fitted can be moved along the device, or the desired relative movement can be obtained by a movement of the application device and object 66.
- the cut paper web start 30.1 can be produced by pressing the knife 51, which is attached to the cutter bar 50, against the roller 10 by the working means 52, as shown in FIG. 11.
- the paper web is cut off in shape and position preferably exactly to the adhesive tape 44 ′′ already glued to the outer surface of the paper web, and then the new cut paper web beginning 30.1 is turned by the roller 10 and / or by turning the paper roll 8 counterclockwise from the roller 10 pressed and glued to the adhesive surface 63.1, the roller 10 is only turned back so far that the adhesive surface 63.2 is not touched by it, as shown in FIG.
- the roller 10 advantageously has a surface jacket made of an elastomer.
- the knife 51 can be designed in such a way that the new path start can be executed in any shape.
- the cutter bar 50 can also be designed such that it can be equipped with different cutters (not shown), which can be used optionally.
- the cut-off remainder of the paper web can now be transported through the belt system 20-23 into the collecting container 24 after the roller 10 has pivoted away from the roller 35.
- the adhesive tape 44 can be applied parallel to the winding roller axis on the outer surface. However, it is also possible to apply the adhesive tape 44 at an angle to the winding roller axis. For this purpose, the rail 40, the roller 10 and the measurement 51 can be pivoted in their working position by the corresponding angle.
- the roller 10 can then be lifted off the winding roller 8, wherein the winding roller 8 can then be lowered onto the transport carriage 9 and transported further by the latter.
- the device is now ready for processing another winding roll.
