Abstract

Un procédé, particulièrement simple et peu coûteux, de formage d’un film d’ensachage sous vide (10), comprend la formation d’une pluralité de nervures (24), chacune au moyen d’une séquence comprenant : la mise en place d’organes presseurs (14, 16) sur le film, de part et d’autre d’une région (22) du film ; puis le déplacement en translation d’au moins un deuxième (16) des organes presseurs, de manière à réduire une distance séparant mutuellement les organes presseurs, tout en exerçant des pressions respectives sur le film au moyen de chacun des organes presseurs (14, 16) de sorte que l’organe presseur en translation (16) entraîne avec lui le film par friction, moyennant quoi la région (22) du film se déforme en flambage en formant la nervure (24) ; puis l’arrêt du déplacement en translation puis le retrait des organes presseurs (14, 16).
