The press roll cooperates with a counter roll to form a press with a long nip for paper or board machines. The press roll has two end walls; a flexible jacket secured to the end walls; and support members for the end walls. The end walls have bearings for permitting rotation of the jacket and the end walls in relation to the support members. A press shoe of the press roll cooperates with the counter roll to form a pressing zone. Attachment assemblies each have a circular clamping member, which includes a wedge body, and a circular groove disposed on the inside of the end wall to receive the edge portions of the jacket and the wedge body, the groove and wedge body being provided with cooperating wedge forming surfaces. Further, the clamping member includes bolts for pushing the wedge body into the groove and retaining it therein in order to clamp the edge portions of the jacket by means of wedge action, against the end wall. The groove is defined by an outer circumferential surface of the end wall and an outer ring secured to the end wall. The clamping member is located at the inner side of the jacket.
