Abstract
L'innovazione del metodo, oggetto del presente brevetto, è relativa al campo della goffratura in continuo. Nella pratica attuale la goffratura in continuo si realizza mediante cilindri sulla cui superficie è riprodotto un disegno in rilievo e sui quali si comprime il materiale su cui si vuole incidere il negativo di tale disegno. L'utilizzo di un nastro metallico ad anello, chiuso senza giunzione di raccordo, di lunghezza e larghezza variabili in funzione del materiale da goffrare, sulla cui superficie sia riprodotto in rilievo, il disegno in negativo da trasferire permette di sottoporre il materiale da incidere a condizioni di pressione e temperatura differenziate, durante ogni rotazione dell'anello metallico, senza soluzione di contatto matrice-materiale. La possibilità di variare la pressione e la temperatura, utilizzando matrici cilindriche non è realizzabile e ne costituisce quindi un limite in termini di qualità e flessibilità operativa.The innovation of the method, object of the present patent, relates to the field of continuous embossing. In current practice, continuous embossing is carried out by means of cylinders on whose surface a relief design is reproduced and on which the material on which the negative of this design is to be compressed is compressed. The use of a ring metal tape, closed without a connection joint, of variable length and width according to the material to be embossed, on whose surface it is reproduced in relief, the negative design to be transferred allows the material to be engraved to be subjected to different pressure and temperature conditions, during each rotation of the metal ring, without a matrix-material contact solution. The possibility of varying pressure and temperature using cylindrical matrices is not feasible and therefore constitutes a limit in terms of quality and operating flexibility.
