Abstract: A multi-purpose calender having latterly spaced frames mounting four superposed calender rolls with their axes of rotation extending horizontally and three rolls offset relative to a vertical plane. Two outer rolls are provided with two coactive inner rolls intermediate the outer rolls. A first inner roll is mounted with an axis of rotation fixed in a vertical and in a horizontal plane. The frames have slot guides therein mounting beating housings and the bearings therein of the three other rolls adjustably shiftable and crossable independently along respective inclined planes.

Abstract: A method and charging apparatus for feeding successively individual strips of a deformable material to a calender for calendering under pressure between at least two rotatably driven calender rolls. The strips are produced from a strand of an elongated mass of deformable material provided from an extruder or rolling mill which is then cut into individual strips transported to a roller conveyor which positions them in a common plane successively at a selected or determined position extending transversely of the roller conveyor rollers in a direction parallel to the length direction of the calender rolls.
