Abstract
1,185,937. Roller. POLYMER CORP. 26 Sept., 1968, No. 45803/68. Heading F2U. A roller, e.g. a swimming roller in a supercalendar stack for finishing paper, comprises a stationary core 1 and a shell 2 bearing mounted at 5 and 6 on the core, a loose cover 9 being mounted on the shell and formed of a polycarbonate material, e.g. a polyarylcarbonate formed by reacting bisphenol-A with phosgene. Passageways 3 and 4 are provided in the core 1 to direct fluid, e.g. oil, to two chambers defined between the core and shell by a pair of axial wipers (10), Fig. 1 (not shown), on the core, the passage 3 being under pressure to exert a uniform pressure on the shell even when the core is deformed under load. Seals 7 and 8 are provided at the roller ends, flanges 9a on the roller end plates preventing axial movement of the cover. Pressure cylinders 14, 15 act on the core journals to apply pressure to the roller stack.
