ABSTRACT:
A calender wherein the bearings for the end portions of the uppermost roll carry pressure transducers in the form of inflatable plenum chambers or hydraulic cylinder and piston units operable to bear against the lower end faces of vertical feed screws which are axially movably mounted in the support to move the bearings through distances of up to 800 mm. The pressure transducers can shift the bearings for the uppermost roll through distances of up to 25 mm, and they are movable transversely of the respective feed screws or vice versa to compensate for manufacturing tolerances, wear and/or unequal stresses. The lowermost roll is normally held at a predetermined level by a pair of fluid-operated motors which urge the respective bearings against the undersides of stops provided therefor on the support.
