Abstract

A roll assembly comprising a rotatable roll (1 in FIG. 2) and a second roll (2 in FIG. 2) cooperating therewith, in which a pressing element (17) to effect displacement between the rolls along a pressure plane of the roll assembly is located in one of the rolls (1,2) and in which both rolls are supported at either end by respective support members (5,6). Prior to operation of the roll assembly, dumbbell-like shaped connecting parts (7) installed in corresponding cut-outs (9) in the support members (5,6) are tensioned and thereby securely form-locked by actuating the pressing element (17). Locking action is released by subsequent deactivation of the pressing element (17) after which the connecting parts (7) can be withdrawn. Two principal advantages of this arrangement, are the compacter construction, enabled by the fact that the frame no longer bears the pressing forces of the roll assembly, and the ease and speed with which components such as rolls, roll jackets or felt belts can be changed.
