Abstract

1286017 Film chill roll FARBENFABRIKEN BAYER AG 30 Sept 1970 [21 Oct 1969] 46428/70 Heading B5B [Also in Division F2] A cooled roll with a surface roughness of 13 Ám (possibly Œ5 Ám) may be used for preparing a film of thermoplastic material, e.g. polyamide, polycarbonate, polyethylene, polyproplyene, polyester or soft P.V.C., which is extruded on to the roll. The roll surface may be prepared by grinding, then chromium plating to a depth of 0À3 to 0À4 mm., grinding this layer and electrochemically roughening.
