Abstract
Il presente trovato ha come oggetto un impianto per la termoformatura di materiali in lastra, con stazioni di preriscaldamento, caratterizzato dal fatto di comprendere, a valle di un caricatore automatico di lastre in materiale termoplastico, una prima camera di preriscaldamento, per il riscaldamento della lastra fino a circa il 30% della temperatura finale di plastificazione, una seconda camera di preriscaldamento, per il riscaldamento fino a circa il 60% della temperatura di plastificazione, una camera di plastificazione, per il riscaldamento finale della lastra fino alla temperatura di plastificazione, una camera di formatura sotto vuoto ed una stazione di scarico.Sono, inoltre previsti trasportatori, per il trasferimento passo-passo delle lastre, attraverso l'impianto, fino alla stazione di scarico.
