Pressvals

摘要

A press roll (2) intended, together with a press shoe (15), to cooperate with a counter roll (1) to form a press with long nip for paper or board machines, said press roll comprising two end walls (4, 5), a jacket (3), the edge portions (8, 9) of which are secured by an elastic clamping ring (24) to peripheral parts (6, 7) of the end walls, a form-stable clamping ring (25) being screwed to the inner side of the end-wall part (6, 7) to clamp the outwardly expandable elastic clamping ring (24) between itself and this so that the edge portion (8, 9) of the jacket (3) is clamped firmly against a counter-support member (27). According to the invention each end wall comprises a plurality of distance elements (57) which are placed at least partially between the form-stable clamping ring (25) and the end-wall part (6, 7) in order to define a least axial distance between the form-stable clamping ring (25) and the end-wall part (6, 7).
