Abstract
Procédé pour la fabrication d'un sac d'emballage à fond au moins sensiblement rectangulaire ou carré, selon lequel à une extrémité d'une ébauche tubulaire on commence par réaliser par pliage deux volets triangulaires ou trapézoïdaux symétriques ménageant entre eux une fente longitudinale, apres quoi on replie les cornes desdits volets l'une sur l'autre pour les fixer. Selon l'invention, ce procédé est caractérisé en ce que, avant repliement des cornes des volets, pour rendre ledit fond étanche, d'une part, on fixe sur lesdits volets une étiquette recouvrant la fente jusqu'au-delà desdites lignes de pliage des cornes et, d'autre part, on thermoscelle lesdites cornes au moyen de zones de thermoscellement allongées, transversales et croisant les extrémités de ladite étiquette, puis on procède au repliement et à la fixation desdites cornes. Fabrication de sacs étanches à l'humidité.
