Abstract

Trattasi di un'apparecchiatura per la bicchieratura ed il raffreddamento di tubi in materiale termoplastico, comprendente due morse (7) ed un tampone (2) meccanico ad espansione, operanti rispettivamente sulle superficie esterna ed interna del tubo (4) termoplastico, detta apparecchiatura (1) comprendendo altresì un involucro (15) tubolare, interposto tra le morse (7) ed il tubo (4) termoplastico, individuante una camera (18) interna, in pressione per la formatura esterna del tubo (4) termoplastico, nella quale sfocia un unico foro (19) di immissione del fluido gassoso in pressione, tale foro (19) facendo parte di un circuito (20) di circolazione forzata del fluido gassoso, mantenuto in pressione all'interno di detto involucro (15), dotato di un foro (42) di emissione del fluido stesso, e non in pressione all'interno di detto tampone (2), detto circuito (20) comprendendo mezzi (21) di raffreddamento almeno del fluido gassoso in pressione, in modo atto a realizzare contemporaneamente la forma definitiva ed il raffreddamento di detto tubo (4) termoplastico.FIG. 1
