Abstract

L'invention concerne un procédé pour produire une unité d'emballage d'articles en plastique multicouche réalisés à partir d'un film, ces articles étant fixés à un support sur une face et présentant pratiquement le même contour, notamment des gants de protection superposés. Une bande (6) du matériau de support et plusieurs bandes (7, 8, 9, 10) du film sont acheminés par des dispositifs de transport et un processus de soudage s'effectue dans au moins deux postes de soudage (16, 17) situés l'un derrière l'autre dans le sens de déplacement (B) de la bande (6) du support. La position de l'article en plastique produit dans un premier poste de soudage (16) est déterminée dans le poste de soudage suivant (17) par l'avancement des dispositifs de transport se présentant sous la forme de rouleaux entraîneurs (18, 19). Ces derniers sont mus par des servomoteurs (20, 21) commandés en mode synchrone avec une progression de pas constante. La distance A séparant les postes de soudage (16, 17) est un multiple entier d'un pas de progression équidistant respectif des servomoteurs (20, 21), ce qui permet, par exemple, de positionner parfaitement l'un au-dessus de l'autre les gants d'une paire.
