Title (EN) CRUSH ROLL ARRANGEMENT FOR A CARD WEB
(FR) ROULEAU ECRASEUR POUR METIER A CARDER
Abstract: front page image
(EN)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).
(FR)Un rouleau ecraseur pour metier a carder comprenant deux rouleaux (6) et (10) travaillant ensemble, par exemple pour l"ecrasement des graines et des particules d"enveloppes dans les metiers a carder. Au moins un des deux rouleaux (6) et (10) est creux, le manchon cylindrique (19) est pressurise interieurement et se deforme radialement. Par cette deformation qui est contre-carree par un second rouleau, la pression d"ecrasement est creee entre les rouleaux (6 et 10). Le manchon (19) peut, entre autres solutions, etre d"epaisseur variable le long de sa longueur de telle maniere que la deformation radiale puisse etre adaptee le long des rouleaux (6 et 10).
