Abstract

In un dispositivo per il taglio longitudinale di un nastro di materiale e per il successivo allargamento di almeno due nastri parziali generati in questo modo in una macchina di lavorazione di nastri di materiale, in particolare in una macchina da imballaggio, nella quale l'allargamento avviene tramite le guide di deviazione previste per ogni nastro parziale, con grado di allargamento regolabile, secondo l'invenzione è previsto che le guide di deviazione (6, 6') siano dei profilati cavi alimentati nel loro interno con aria compressa, previsti fissi rispetto alla rotazione, che presentano almeno nella zona di avvolgimento del nastro di materiale (4) una pluralità di aperture (8, 9) per l'uscita dell'aria compressa dalla zona interna dei profilati.
