The roller has a roller body (1) forming a modifiable circular path as a contact surface for a material web during rotary motion of the roller body. The roller body is provided with two conical roller elements (2) that are attached with each other. The roller elements are rotatably arranged on a common central axle shaft (3) via eccentric sockets for formation of a recess and for enlarging certain areas that are attached to each other. The eccentric sockets are connected with the shaft at both sides. |
