Abstract

Procédé de fabrication de produits de remplissage pour emballages par formation en continu de corps creux sans injection forcée d'air dans un tube en résine synthétique. Dans un premier temps, le procédé consiste à soumettre un tube (1) en résine synthétique à l'action d'unités d'aspiration (3, 5) afin de le fixer à celles-ci, et à rapprocher du tube (1) ainsi fixé une unité mobile de soudage transversal (4) afin de pratiquer dans le tube (1) un orifice d'introduction d'air (81) au moyen d'une aiguille perceuse (43) montée sur l'unité mobile de soudage transversal (4). Ensuite, on introduit de manière naturelle de l'air dans le tube (1) en écartant l'une de l'autre les unités d'aspiration (3, 5) auxquelles est fixé par aspiration ledit tube (1). On enferme l'air dans le tube (1) par soudage thermique du tube (1) à l'unité mobile de soudage transversal (4), puis on partage en deux le corps creux formé par ladite unité mobile de soudage transversal (4). A cette fin, on effectue le soudage thermique d'une partie intermédiaire de ce corps à l'aide d'une unité mobile de soudage longitudinal (6). Les corps creux sont formés en continu à mesure que leur pression interne augmente.
