Abstract

487,948. Machines for calendering, extruding, and otherwise treating rubber compositions. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., BOWYER, E., and SMITH, G. M. Dec. 31, 1936, No. 35840. [Classes 70 and 87 (ii)] A device for feeding rubber composition to machines for calendering, extruding, or otherwise treating them comprises a feeding box, hopper or a similar enclosure and a pressure member floating with contact pieces, between which the material is fed, on the excess of the material accumulating in the inner part of the box and acted on continuously by a force which causes them to press the composition inwards until it is taken up by the machine. Figs. 1 and 2 show an extrusion machine provided with a feeding device of the kind; the floating pressure member comprises a frame 9 carrying a pair of spaced rolls 11 pressed on to the composition in the hopper 12 by springs 8 and between which the composition is fed in the form of a strip 12 from a coil 5. The Specification also describes a calendering-machine provided with a similar feeding device.
