Abstract: 893,513. Calenders. KUMPF, W. Sept. 22, 1960 [Sept. 24, 1959], No. 32527/60. Class 96. In a calender for producing a gloss on paper sheets coated with varnish, the calendered sheets are removed from the calender roll 1, Fig. 1, by a suction roller 5 disposed with a clearance equal to or just slightly greater than the sheet thickness, only those apertures of the suction roller in the region facing the calender roll being connected to suction. The varnished sheets are fed from a table 24 to the calender roll 1 by being passed between a feed roller 23 and a pressure roller 2, the clearance between the rollers being adjusted to the thickness of the paper by a setting-screw 28, and are pressed against the calender roll surface by pressure rollers 2, 3. They are then drawn off the calender roll on to the suction roller and held thereon by one or more frictionally-driven endless belts 16, being finally blown off by one or more tangentially aligned blowers 20 on to a support or conveyer 19. The suction roller comprises a rotatably mounted hollow cylinder with outwardly widening suction apertures provided over its whole circumference and is driven by frictional engagement of the calender roll with strip friction linings 7, 7<SP>1</SP> at at least one of its ends whose thickness is substantially equal to that of the calendered sheet.
