ABSTRACT:
The invention concerns an apparatus for the continuous production of oriented hollow bodies from a thermoplastic by blow extrusion which comprises a device for the extrusion of at least one continuous tubular parison from the thermoplastic and also comprises (1) at least one station for blow-molding preforms which is capable of receiving at least one preform mold which can seize a length of extruded parison while leaving open one end of this length which protrudes beyond the mold, and which is equipped with at least one blow nozzle which can be introduced into the open and protruding end of the length of parison so as to permit the production of preforms provided with a definitive molded neck (2) at least one fixed station for the heat-conditioning of the preforms to their orientation temperature and (3) at least one fixed station for the final blow-molding of the conditioned preforms equipped with at least one blow nozzle and at least one final blow-mold of which the cavity reproduces the shape of the desired oriented hollow bodies in which the transfer of the preforms from one of these station to the others is ensured by gripping means mounted on a movable equipment which act on the part of the preforms located above their neck and which move so as to disengage the preforms from the successive station, transfer them to the next station and engage them in this station.
