ABSTRACT:
An apparatus for the clearance-free mounting of at least one of the rollers in the support column of a calender. The mounting is for producing plastics material films achieved by means of a roller bearing which is divided into three, a central section or ring and two laterally outer sections or rings in a direction transverse to the major axis of the roller journalled to rotate therein. Each bearing ring or section comprises an inner ring portion, at least one row of cylinder rollers, an outer ring portion and a bearing body portion. Pressure applicator means are provided for displacing the central section relative to the two laterally outer sections or rings in a direction towards and away from the roller journalled therein so as to eliminate play within the bearing. To eliminate the play between the bearing body and the calender support column, an additional pressure applicator means is provided which is incorporated in the calender support column.
