Abstract

978,060. Moulding plastics material. H. GIEHLER. Jan. 15, 1963 [Jan. 17, 1962], No. 1710/63. Heading B5A. A tubular or channel-shaped extrusion of plastics material with transverse walls is produced by forming an extrusion without transverse walls and passing it through or below moulding jaws or dies having means to inject plastics material between the jaws to form a wall transverse of the extrusion, the moulding jaws or dies being adapted to move along with the extrusion between the extruder and an extraction device. An extruded tube 17 is enclosed between mould parts 11, 11<SP>1</SP> brought together by a pressure medium, and piston and cylinder injection devices 8, 8<SP>1</SP> are operated to inject plastics material through needles 10, 10<SP>1</SP> carried by the parts 11, 11<SP>1</SP> to form a transverse wall 13. The unit 2 comprising the mould 11, 11<SP>1</SP> and the injection devices 8, 8<SP>1</SP> is moved along a spindle 16 at the speed of travel of the extruded tube 17. The moulded product is withdrawn between endless moving belts 14, 15, Fig. 1 (not shown), and may be used as buoyancy cords on fishing nets or may be split longitudinally to form feeding troughs or shades for lighting fittings. Additionally a section of the extruded and partitioned tube may be blown into a spherical shape in a mould. Two alternative apparatuses are described for injection moulding transverse walls in channelshaped extrusions, and in which parts of the injection mould are pivotally mounted for movement into and out of their operative positions.
