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). |
