The roller (01) has a gear that is located in the interior of the roller, to generate a speed that is different from that of the roller sleeve (02). The roller has a bearing that is positioned at an angle (alpha ) to the rotation axis (12), to generate axial travel (h). The bearing has two rings (34,38), of which one is fixed with respect to the axial direction of the roller and the other is fixed to the roller wall (02). |
