ABSTRACT:
A calender wherein the end portions of the lowermost roll of the roll train was mounted for movement along vertical guide rails on the stand. The lowermost roll is movable upwardly by two upright hydrostatic cylinder and piston units with plungers whose axes are coplanar with the axis of the lowermost roll. When the cylinder and piston units lift the lowermost roll to operative position, shoulders on the bearings abut against stationary stops on the stand and the stops are disposed only at one side of the common plane of the aforementioned axes so that the bearings tend to jam against the adjacent portions of the guide rails as soon as the shoulders engage the respective stops. The jamming action is enhanced if the stops are remote from the aforementioned plane and if the guide rails have T-shaped heads which are slidable in complementary T-shaped grooves of the bearings. The stops are installed at the level of the axis of the lowermost roll.
