Abstract

781,999. Making rubber sheeting. UNITED STATES RUBBER CO. June 24, 1955 [Aug. 31, 1954], No. 18282/55. Class 87(2). Rubber is extruded by independently driven screws 19 ,33, Fig. 2, through a transversely extending extrusion passage 110, having replaceable and radially adjustable members 113, 114, into a space formed between a floating, rotatable plain or engraved drum 40 and (at first) an extension member 92 and (later) a flexible band 90 fixed at one end by a block 94 and tensioned at the other end by a hydraulic piston 102. To start a moulding operation, either the band is not tensioned until the rubber reaches the outlet end of the band or a sheet is placed between the band and the drum and the band tensioned. The drum is rotated by the frictional force of the rubber. In a modification, Figs. 6 and 7 (not shown) the speed of rotation of the drum may be controlled by driving the drum by a gear which engages with a ring gear fixed to the inside of the drum. Friction between the rubber and the band is reduced by supplying lubricant through a passage 146. The drum is supported by (a) flanged rollers 46, 47, mounted in a carriage 51 which may be moved to and from the extrusion head on rails 53, (b) rollers 67, 68, and backing rollers 61, mounted on spaced plates 60. The drum is held an adjustable distance from the extrusion head by screw-threaded tie rods 75 engaging members 77, 79 on the drum and head, respectively. Side flanges are provided on the drum to enclose the rubber. The sheet is vulcanized by radiant heaters 71.
