Abstract

996,102. Feeding plastic material to moulding machines. ECKERT & ZIEGLER G.m.b.H. May 23, 1963 [May 26, 1962], No. 20648/63. Heading B5A. A mixture of substances is fed to the form tool of a forming machine, e.g. an extrusion die or the mould F of an injection moulding machine by feeding separately to a worm 2, a basic substance and one or more additives, the worm being driven at a selected rate to feed the mixture to the form tool, and the or each additive being fed to the worm at a selected rate proportional to the feed speed of the worm, thereby maintaining a preselected composition of the mixture. In the apparatus illustrated, the basic substance, an elastomer or a plastics material, is fed from a hopper 1 to the worm 2, and an additive 8 such as a cross-linking agent or a hardener, is fed from a cylinder 4 by a double piston 5, 7 actuated hydraulically or pneumatically to apply a feed pressure proportional to the rate of rotation of the worm 2. In alternative embodiments the piston 5 is actuated by a threaded spindle and driving nut, and is replaced by a worm, respectively.
