Abstract

Fond en croix pour sac fabriqué à partir d'un segment de feuille tubulaire thermoplastique, muni d'un feuillet de recouvrement de fond. Le feuillet de recouvrement de fond dépasse les volets latéraux de fond et est soudé avec les bords de ces volets et avec ceux des remplis d'angle; les côtés du feuillet de recouvrement de fond sont rabattus autour de lignes de pliage situées à l'intérieur des joints de soudure assemblant le feuillet avec les volets latéraux et les bords du feuillet replié des deux côtés, parallèles aux bords des volets latéraux, et se recouvrant, sont soudés ensemble. Application notamment aux sacs à valve.
