Title (EN) APPARATUS FOR SEALING THE OVERLAPPING EDGES OF A TUBULAR FILM
(FR) APPAREIL POUR COLLER LES BORDS SUPERPOSES D'UN FILM TUBULAIRE
Abstract: front page image
(EN)The apparatus comprises means (31, 33) for guiding and for holding the longitudinal edges of the film to be sealed so that they overlap with an intimate and distributed contact and comprises in an opposing position, a short distance from these guide means, a sealing head (6) made in good thermal insulator and with a low coefficient of friction in relation to the film, which directs onto the said film jets of hot air at an appropriate temperature and an appropriate pressure, through longitudinal slits of appropriate dimensions (35). The sealing head is connected to supply and control means (39-44) that keep it fully operational or have it promptly fully operational, the head being mounted on means (45) for moving it rapidly towards or away from the film to be sealed.
(FR)L'appareil comprend un moyen (31, 33) pour guider et garder en un contact étroit et réparti les bords longitudinaux du film à coller et comprend également dans une position opposée, à une courte distance de ce moyen de guidage, une tête de collage (6) faite d'un matériau calorifuge et présentant un faible coefficient de frottement par rapport au film, qui dirige sur ledit film des jets d'air chaud à une température appropriée, à travers des fentes longitudinales de dimensions appropriées (35). La tête de scellement est raccordée au moyen d'alimentation et de contrôle (39-44) qui la maintient dans un état opérationnel ou permettant de la mobiliser très rapidement, ladite tête étant montée sur un moyen (45) permettant son déplacement rapide en direction du film à coller et en sens inverse.
