Abstract

Una calandra curvatrice per piegare lastre o lamiera a ciclo di lavoro programmabile; una unità di processo centrale attraverso idonei sensori controlla le posizioni dei rulli della calandra modificandole in funzione di dati programmati che di volta in volta possono essere modificati dall'operatore, o automaticamente, in funzione delle caratteristiche della lamiera in fase di lavorazione. L'uso di un dispositivo di rilevamento a tre punti consente di controllare il diametro che la macchina sta conferendo alla lamiera, intervenendo per apportare le necessarie correzioni.
