Abstract

931,748. Extruding machines. ANSTALT UNDA. Jan. 24, 1962, No. 2669/62. Class 87(2). An apparatus for the continuous extrusion of material comprises two piston-cylinder units 1, 2 connected by pipes to a valve 3 so arranged that it keeps the pipe at the higher pressure connected to a material outlet 4, the units 1, 2 being adapted to feed material to the outlet 4 alternately and being filled during their return travel by a further pistoncylinder unit 7 which is connected by the double non-return valve 8 to the outlet pipes of the units 1, 2; each of the units 1, 2, 7 is connected by the rods 9, 10, 11 to the hydraulic piston cylinder units 20, 21, 25, and the rods 9, 10 carry projections 34 38 49, 35 37 39, for actuating the motors 14, 15 driving the pumps 12, 13 of the hydraulic drive in an appropriate sequence.
