Abstract
L'invention concerne un procédé pour former une bande de film en matière plastique à double épaisseur comportant des panneaux se succédant suivant la longueur. Le procédé selon l'invention comporte l'entraînement de la bande tirée d'un rouleau d'alimentation 30 pour le faire passer entre un tambour cannelé 14 et une lame de coupure à chaud 45 comportant des interruptions sur son bord de coupe pour former des fentes séparées par des intervalles sur la largeur de la bande avec des intervalles prédéterminés le long de la bande, les deux couches étant ainsi soudées dans les zones d'affaiblissement et les perforations ayant une longueur de dix à quinze fois la longueur d'un intervalle. Une bande selon l'invention convient en particulier pour empaqueter des marchandises dans un magasin ou autre.
