Abstract: Process for mould release of a hollow plastic body moulded by blowing by means of a nozzle in which after cooling the hollow body and opening the mould, a fluid under pressure is injected into the hollow body through the nozzle in the bottom region of the hollow body. The process may be completed by a mechanical ejector acting from the outside at the neck position of the hollow body after the nozzle has been removed from the mould.

Abstract: Apparatus for the continuous production of oriented hollow bodies from a thermoplastic, which includes a device for the production of a continous tubular parison from a thermoplastic. There is also a machine for blowing preforms which is fed with the continuous tubular parison and of which the molds, aligned end to end contiguously on a first rotary carrier, make it possible to produce separate preforms of which the neck is molded to its definitive or ultimate shape. A device is provided for deflashing the neck of the preforms, as is a device for thermal conditioning which brings the preforms to their optimum orientation temperature. A final blowing machine is used which includes a plurality of molds mounted on a second rotary carrier as is a transfer device which bring the preforms from the preform blowing machine to the final blowing machine while causing them to pass successively through the deflashing device and the thermal conditioning device.
