DE2132893C - Take-off roller for tension-free removal of a film web moved by a driven roller - Google Patents

Description

"Ig ^
contrary to the
indicates is.

falling speed of the two rollers 1.2 equal to each other is great.

The operation of the take-off roller according to the invention is as follows:

The rotary movement of the driven embossing roller 1 is transmitted to the take-off roller 2 via the two Transfer friction wheels 6. For example, if the embossing roller 1 rotates clockwise, they will rotate both friction wheels 6 and thus also the corresponding internal toothing? in the opposite Clockwise. This rotational movement of the internal gearing? is transferred to the one pinion 8, which stationary but rotatable in the plate 9 is mounted. The rotary movement of this pinion 8 takes place with respect to the internal gearing? in the same direction. This rotational movement of the pinion 8 is transmitted via the pinion 11 the gear 12 transmitted. The pinion 11 rotates clockwise while the gear 12

In practice, one very often sees the. For the sake of clarity, FIG. 2 shows the Task set, from a driven roller, 45 drawing only part of the two rollers 1, 2 z. B. an embossing roller on a take-off roller is shown small. The shaft 3 is fixedly mounted so that the take-off roller 2 can rotate around an extraordinarily soft and soft ren diameter,
Remove film that is sensitive to tensile forces. Derar- The embossing roller 1 is connected to friction wheels 6, term very thin, sensitive to tensile forces and of which only one friction wheel 6 in FIG. 2 soft foils are shown, for example, for the rkrstel 50. Each friction wheel 6 has an inner lung used by so-called baby panties. toothing 7, which around the entire inner circumference In order to prevent the two friction wheels from being arranged around tears in the film in this particular case.
avoid, it is necessary that the diameter In this internal toothing 7 engages a pinion 8. different two rollers have one and the same which have a peripheral speed fixedly connected to the shaft 3, because only then is plate 9 fixed but rotatably mounted. In addition, this guarantees that the pinion 8 has a shaft in the film web that is continuously pulled off by the embossing roller and that no tension members 10 are mounted in the plate 9. The pinion 8 engages or pressure forces are introduced. into another pinion 11 (Fig. 1), which is also The object of the invention is therefore to provide a trigger that is fixedly but rotatably mounted in the plate 9. roller to create whose work surface - over 60. The rotary movement of this pinion Il is on a So which the film web is directed - transmitted with the gear 12, which via bushes 13, 14 driven roller, e.g. B. embossing roller, not connected in Bc- with the jacket of the take-off roller 2. · Rühiung arrives and its circumferential speed, so if the rotatably mounted about the shaft 3 nevertheless, the peripheral speed of the gear wheel 12 performs a rotary movement, then it is upstream embossing roller. 65 this rotary movement in the same direction on the jacket and According to fulfillment, this task is thus transferred to the take-off roller 2,
solves that each friction wheel has an internal toothing. The internal toothing 7, the two pinions 8, 11 sits, in which a stationary but rotated about its axis and the gear wheel 12 are designed so that the
