ABSTRACT:
The present invention concerns a crush roll arrangement for a card web with two co-operating working rolls 6 and 10 as used, e.g. for crushing of seed and shell particles contained in a thin card web. At least one of the two rolls 6 and 10 is designed as a hollow member, the cylindrical sleeve 19 of which is pressurized inside and thus deforming in radial direction. By this deformation, which is counteracted by a second roll, the crushing pressure is generated between the working rolls 6 and 10. The sleeve 19 can, among other solutions, be of varying thickness along the longitudinal direction of the roll in such a manner that its radial deformation can be adapted in longitudinal direction along the working rolls 6 and 10.
