<p>The roller holder (6) has an angular lever (3) at one end. This is pivoted on a dismounting unit (2) such that the roller holder (6) can be swung to the center of gravity of the dismounting unit (2). To swing the angular lever, its end is connected to an actuator (7), i.e. a cylinder, which is pivoted on the dismounting unit, where its (7) location is adjacent to the center of gravity of the dismounting unit. For each roller stub axle, the dismounting unit includes an L-shaped carrier; these are inserted into the roller stack prior to roller dismounting. Each roller holder has a pair of jaws (16) curved to grip the stub axle. The rotation axis of the bearing (11) holding the angular lever on the dismounting unit, is at right angles to the transverse extent of the dismounting unit.</p> |
