Abstract

Une des améliorations consiste à établir, entre le poste (1) de formation des sacs et le poste (3) de remplissage des sacs, un poste intermédiaire (2) dont la distance d'espacement par rapport au poste de remplissage (3) est considérablement plus petite que la distance existant entre ce dernier poste et le poste de fermeture (4) de sorte que, pendant le déplacement du chariot (9) de transfert de sacs (8), ces derniers arrivent au poste de remplissage (3) en un temps sensiblement plus court que celui requis pour le transport des sacs vers les autres postes, ceci permettant d'avoir un temps de remplissage plus long. Une autre des améliorations consiste à prévoir un mécanisme soudeur pour le renforcement des extrémités des sacs, après leur remplissage et leur fermeture. Une autre de ces améliorations consiste à doter la machine d'ensachage d'une unité de formation de sacs, cette unité étant prévue pour fragmenter la bande tubulaire continue à partir de laquelle on obtient lesdits sacs et pour fermer par soudage l'extrémité inférieure de chacun des sacs, tout ceci étant effectué dans des conditions optimales pour que les sacs puissent supporter la phase suivante de remplissage.
