Apparatus for the continuous production of oriented hollow bodies

摘要

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. The preform transfer device includes an endless chain provided with carriers so arranged so as to support the preforms below their neck, which has already been molded.
