Abstract

852,387. Extrusion machines. ALEGMENE KUNSTZIJDE UNIE N.V. Nov. 14, 1958 [Nov. 22, 1957], No. 36752/58. Class 87(2). An extrusion machine for rods and bars has at its outlet a cooled moulding device 8, rollers 30, 31 for withdrawing the cooled rod and, between the moulding device 8 and the extrusion machine 2, an insert 5 having one or more passages 6 arranged to direct the plastic material onto the walls of the moulding device. The direction of the material shortens the length of the plastic cone 10 giving more even and void free cooling. In Fig. 3, the material is passed through a pressure regulating device 23 having thermometers 22, 25 and a pressure gauge 24 and thence through a tempering device 26 where the temperature of the material is adjusted before passing the insert 5.
