Definitions

  • the invention relates to a roller arrangement consisting of a pair of rollers interacting at a nip with a punching roller having a punching pattern on the lateral surface and a counter-pressure roller, the nip being predetermined by races provided on the longitudinal ends of the two rollers and rolling against one another during operation so that a part the layers of a multi-layer web guided through the nip are to be punched through the punching pattern and at the same time at least one layer of the web remains essentially unharmed.
  • roller arrangements which consist of a stamping roller having a stamping pattern on the lateral surface and a smooth counter-pressure roller.
  • the distance of the punch knife from the The surface of the counter-pressure roller is adjusted so that a multi-layer system which runs through the gap between the two rollers is cut exactly to the intended depth.
  • This separation system naturally assumes that the layer thickness of the papers or foils used is always exactly the same. In practice, however, the layer thicknesses vary slightly, in particular fluctuations in thickness of a few hundredths of a millimeter cannot be ruled out.
  • the gap between the punching and counter-pressure roller must be readjusted if the layer thickness of the films or papers used deviates by more than 1/100 mm from a specified standard. This adjustment is time-consuming and requires complicated adjustment devices.
  • the object of the invention is to simplify the adaptation of a roll arrangement mentioned at the outset to slightly varying layer thicknesses of the web to be treated in such a way that it can be carried out in a few steps without special adjustment means.
  • the solution according to the invention is that one roller has two or more races which are graduated in the same direction or to the same extent in the axial direction at their longitudinal ends and that the rollers in the direction of the two axes relative to one others are slidably mounted.
  • two or more pairs of the same races are provided on one roller, which are to be brought into contact with the races of the other roller by axial displacement of one or the other roller.
  • the gap between the roller surfaces is larger than when a pair of smaller diameter races engage the races of the other roller.
  • pairs of races according to the invention should differ in the range of the tolerances occurring in the machined tracks, that is to say in the order of magnitude of hundredths of a millimeter.
  • the races can have approximately the same width as previously used individual races, for example approximately 40 mm.
  • the pairs of races graded in diameter are provided.
  • the counter-pressure roller has the stepped pairs of races and is movably supported in the axial direction relative to the spatially fixed punch roller.
  • the axially movably mounted roller should be assigned an axial drive for gradually engaging a pair of the races with the individual races of the other roller.
  • the roller arrangement consists of a pair of rollers interacting at a nip 1 with a stamping roller 4 having a stamping pattern 2 on the lateral surface 3 and a counter-pressure roller 5 with a smooth jacket 6.
  • the stamping pattern 2 is part of a jacket 3 of the stamping roller 4 laid die 7, which is pressed, for example by magnetization of the punch roll 4 to the jacket 3.
  • the punching roller is supported with its axis 8 in bearings 9 and has a drive 10.
  • the drive axis 8 is coupled to the drive axis 13 of the counterpressure roller 5 via a gear transmission with gears 11 and 12.
  • the punching roller 4 can be raised or lowered in the direction of the arrow 18 by means of a motor 14 and a shaft 15 as well as a gear 16 with the aid of spindles 17.
  • a motor 14 and a shaft 15 as well as a gear 16 with the aid of spindles 17.
  • the races 19 of the punching roller 4 provided on the longitudinal ends come into engagement with races 20, 21 or 22 of the counter-pressure roller 5 held in bearings 23 with their axis 13.
  • the counter-pressure roller 5 can be moved back and forth in the axial direction 25 with the aid of a lifting cylinder 24 such that one of the pairs of races 20, 21 or 22 comes into engagement with the pair of races 19.
  • the drive wheel 12 provided on the axis 13 of the counter-pressure roller 5 becomes corresponding in the axial direction broadly designed.
  • the gearwheels 11 and 12 can be constructed without further ado in such a way that they ensure that the rollers 4 and 5 remain sufficiently precise in the same way when the spacing changes of the axes 8 and 13 are provided.
