Abstract

1,195,706. Blow-moulding; moving extruder system. OWENS-ILLINOIS Inc. 23 June, 1967 [24 June, 1966], No. 28994/67. Heading B5A. Blow-moulding apparatus wherein the extrusion system supplies material to and moves between at least two blow-moulding stations so that extrusion is effected at one station while blowing is effected at another, comprises blowmould halves 26/28 and 30/32, opened and closed by hydraulic cylinders 62, 74 and rack and pinion mechanisms 99/103 and 98/102, vertically reciprocable injection-neck moulds 22, 24 and extrusion assembly 16 movable therebetween. Material is injected into a neck-mould, e.g. 22 at one station (say) 12 while blowing is effected at the other (say) 14, the still closed neckmould 22 then being withdrawn upwardly while continuing extrusion; blow-moulds 26, 28 are then closed about the extrudate which is severed by cutting means 82 and the extruder assembly 16 moves across to the other station 14, the neck-mould 24 of which is lowered into engagement therewith after a previously blown article is removed and the blow moulds 30, 32 opened. The extrudate is blown at the first station 12 while injection and extrusion is effected at the other 14, the blown article being withdrawn by take-out means 86. The extruder screw may be axially reciprocable. The article produced may have an offset neck portion, formed by moving extruder assembly 16 back slightly during extrusion.
