ABSTRACT:
In the production of hollow bodies from a thermoplastic material, in which preforms are produced from thermoplastic material by molding, each resulting preform is transferred to a final blow-mold, and each preform is molded in a blow-mold to produce a desired final body, the production of each preform is carried out to provide the preform with a false neck having at least one positioning lug, and transfer of each preform to the blow-mold is carried out in such a manner as to cause the preform to have a predetermined angular position relative to the blow-mold by the action of its associated positioning lug.
