Abstract

815,286. Extrusion and injection moulding-machines. GILBERT, N. W. Sept. 1, 1955 [Sept. 1., 1954], No. 25365/54. Class 87(2). An extrusion or injection moulding machine comprises a cylinder, having an annular system of circular channels 5, formed in a solid member 2, and surrounded by induction heaters 12 which may be of the kind described in Specification 772,424 [Group XI]. The channels are located as near to the periphery as possible.
