Title
(EN) STRUCTURE, METHOD, AND DEVICE FOR SPLICING LAMINATED FILMS
(FR) STRUCTURE, PROCEDE ET DISPOSITIF POUR L'EPISSAGE DE FILMS LAMINES
Abstract
(EN)
A method of splicing laminated films, comprising the steps of splicing extended base film layers (3, 4) to each other in a principal rafter shape at a connection part between the rear end portion and top end portion of the laminated films (1, 2) having the extended base film layers (3, 4) and sealant layers (5, 6) to make the interconnected part of the laminated films sufficiently contribute to the manufacture of a packaging bag and provide excellent airtightness and sealability to the connection part itself, and providing a tensile strength necessary for the laminated films to the connection part to eliminate the need of temporary stop of a packaging device when the connection part of the laminated films passes the packaging device so as to increase a working capability and a working efficiency and also increase the yielding of material.
(FR)
Cette invention concerne un procédé d'épissage de films laminés consistant à : former une épissure en forme de chevron avec les couches de base de film (3, 4) en une zone de raccordement entre la partie arrière et la partie supérieure des films laminés (1,2), utiliser les couches de base (3, 4) et les couches d'étanchéité (5, 6) pour que la zone de raccordement soit suffisante pour participer à la réalisation d'un sac d'emballage, la zone de raccordement étant remarquablement étanche à l'air et hermétique ; disposer d'un ensemble offrant la résistance à la traction nécessaire pour que l'avance du sac d'emballage ne doive pas être interrompue au passage de la zone de raccordement tout en améliorant la capacité et l'efficacité de travail ainsi que le rendement du matériau.
