Abstract

Procédé de formage par emboutissage de feuilles plastiques présentant des aptitudes à l'allongement et à la compression différentes selon les directions, selon lequel la tension de formage est répartie sensiblement uniformément dans toutes les directions par le jeu de moyens de maintien mobiles dont la position, tout autour de la zone d'emboutissage, et la course, lors du formage, sont déterminées en fonction de l'aptitude à l'allongement et à la compression de la zone dont ils assurent le maintien et l'accompagnement, de telle sorte qu'en fin d'emboutissage chacun des moyens de maintien et d'accompagnement occupe une position à proximité de la ligne de séparation de l'article formé, la course de ces moyens étant synchronisée avec celle du moyen de formage. L'invention concerne également un dispositif pour la mise en oeuvre de ce procédé.
