Abstract

1,095,468. Blow - moulding. GEORG FISCHER A.G. March 18, 1965 [March 20, 1964], No. 11628/65. Heading B5A. In an extrusion/blow-moulding process the extruder nozzle has a wedge-shaped core 11, 12 along which the cutting edges 21, 31 of the mould halves 2, 3 ride to cut and seal the extrudate without creating flash. Guide rollers 5, 6 are carried by arms extending from the mould halves.
