Abstract

An extrusion-blow moulding machine comprises a two-part mould in which each of the two mould parts is provided with two pairs of impressions (11-12 and 16-17) which are separated from one another by a distance A equal to the increments by which the mould carrier moves reciprocally between two positions. The first pair of impressions (11- 12) is intended to receive the parison and to form the crude article during the blow-moulding/cooling operation and the second pair of impressions (16-17) is equipped with deflashing means (18 to 20, 27 and 30) for removing the scrap and flash formed on the crude article produced. <IMAGE>
