Abstract
Abstract In a calender the nip between a pair of rollers, of which one is obliquely adjustable, is bounded at the sides by plates adapted to the geometrical shape of the nip region and provided with slots, into which a control beam, parallel to the obliquely adjustable roller, engages, the ends of the beam are joined to the bearings of this roller, and the plates are arranged on supporting plates so as to be displaceble by means of a guide device, so that the plates, on oblique adjustment of the roller, are moved along a path which is concentric with the surface of the roller which is not obliquely adjustable.

A calender with rollers forming nips in which the nip between a pair of rollers, of which one is obliquely adjustable, is bounded at the sides by plates adapted to the geometrical shape of the nip region, comprising boundary plates provided with slots, a control beam parallel to the obliquely adjustable roller, which beam engages into said slots and the ends of which join to the bearings of the obliquely adjustable roller, supporting plates on which the boundary plates are displaceably mounted by means of a guide device so that the plates on oblique adjustment of the adjustable roller are moved along a path which is concentric with the surface of the roller which is not obliquely adjustable.
