An embossing calender arrangement capable of embossing a thermoplastic plastics material film on either of its two major surfaces or both surfaces as desired, the embossing calender including two embossing roller sets. The roller sets are each mounted with their axes extending horizontally in one embodiment, in a common frame. The frame is horizontally displaceable beneath a film transfer arrangement by selectively displacing the frame and inserting the film into either one of the embossing nips defined in the roller sets or into both nips successively, the film can be embossed unilaterally on either of its two major surfaces or bilaterally without necessitating major adjustment of the arrangement.

Embossing calender assembly

A calendering apparatus is disclosed which includes means for replacing a desired take-up roller from a take-up roller train. Displaceable, bifurcated carrier means are disposed on the embossing means forming part of the calender apparatus, which carriers can accommodate individual take-up rollers. The rollers are then moved out of the train by such carriers. The embossing means are also displaceable into a position in a lifting mechanism which can be used to collect the roller from the carrier.

Calendering apparatus

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.

Calender roller mounting arrangement

An embossing calender arrangement for thermoplastics material films which can be used for embossing either the top side or the underside of a film as desired comprises an embossing calender, the rollers of which are rotatably mounted in a frame. The frame, together with the calender is displaceable to and from a pivoting position by being suitably mounted and, when in such pivoting position, is pivotable.
