摘要
A tubular premoulding of a thermoplastic, suitable for subsequent shaping to produce containers by a rolling process. The material in a part of a tube is axially oriented as a result of reducing the wall thickness by applying an external pressure which causes the material to flow. The oriented material is moulded by a blow-moulding process into future mouth parts and parts of adjacent neck sections, preferably from two blank parts, joined to one another, of pre-mouldings, the blank parts in the transition between the two mouth parts being severed in order to form two separate blank parts, so that, after closing one end and, if necessary, reworking in order to obtain the requisite closing faces at the other end, the two blank parts each form a tubular pre-moulding.
