Abstract
Apparatus for producing a tubular pre-moulding of a thermoplastic material, suitable for subsequent blow-moulding to form a container comprising a mold in which a future mouth portion and a portion of adjacent neck section of a tube are moulded to form a pre-moulding, preferably from two mutually joined blank parts, by an axial stretch operation and a blow-moulding operation, the parts in the transition between the mouth portions being severed by a cutting device in order to form two separate blank parts. A tubular pre-moulding is produced after closing one end of the particular blank part and, if necessary, reworking in order to obtain the requisite closing face at the other end.
