Abstract
Il dispositivo in oggetto prevede che a monte della porzione (6) riscaldante del rullo saldatore (5), rispetto alla linea di avanzamento (A) ovvero alla rotazione dello stesso rullo, è previsto un elemento sfasatore (7) disposto radialmente sporgente sulla circonferenza dello stesso rullo ed atto, in corrispondenza del passaggio di un pacco di rotoli (3), a traslare relativamente tra loro i due bordi liberi (2a, 2b) nel senso di effettuare un aumento della lunghezza del perimetro di avvolgimento del film (2) così da definire una saldatura degli stessi bordi tale da permettere un successivo rilascio dei rotoli (3) all'interno dello stesso film in corrispondenza dell'uscita dalla stazione (4) di saldatura. (FIG. 1)
