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.
