Abstract

A press roll for a web comprises a support body which is either stationary or rotatable and comprises a press shell which is rotatable over the support body and against a mating roll. A respective shell support element or disc is disposed axially outward of both ends of the support body and the support element has an axially outward, face side. The flexible, liquid impervious endless belt press shell has lateral edge zones. Each edge zone has a respective plurality of outwardly projecting tongues and has cutouts between neighboring tongues. The edge zone is turned radially inward and its tongues are each respectively mounted on a holding element projecting from the face side of the shell support element. Centering elements also on the face side of the shell support element are placed each for extending into and contacting the base of the cutouts between neighboring tongues for positioning the tongues.
