Title (EN) METHOD AND APPARATUS FOR OPENING TAPED BAGS
(FR) PROCEDE ET SYSTEME POUR OUVRIR DES SACS SUR BANDES
Abstract:
(EN) A method of opening a bag includes the steps of providing a bag (9) including a first panel, a second panel, a first bag edge, a second bag edge, a bag bottom, and a bag mouth; holding the bag mouth between a first means for vacuumizing and a second means for vacuumizing; moving the first and second means for vacuumizing such that the bag mouth disengages from the tape (10, 11), activating the first and second means for vacuumizing to draw a vacuum through said means; and further moving the first means for vacuumizing such that the bag mouth opens. In an alternative method, instead of holding the bag mouth with the vacuumizing means, the vacuumizing means can be brought into close proximity to the bag mouth, and activated to draw each panel of the bag mouth to a respective vacuumizing means. Thereafter, both vacuumizing means can be moved upward, and the bag mouth opened. An apparatus for opening a bag is also disclosed.
(FR) Un procédé d'ouverture d'un sac consistant à produire un sac (9) présentant un premier panneau, un deuxième panneau, un premier bord de sac, un deuxième bord de sac, un fond de sac et une embouchure; à maintenir l'embouchure du sac entre un premier et un deuxième moyen de mise sous vide; à déplacer le premier et le deuxième moyen de mise sous vide de sorte que l'embouchure du sac se détache de la bande (10, 11), à activer les premier et deuxième moyens de mise sous vide de sorte que du vide soit produit; et à déplacer encore le premier moyen de mise sous vide de sorte que l'embouchure du sac s'ouvre. Dans un autre procédé, le sac n'est pas maintenu par le moyen de mise sous vide, lequel peut être amené très près de l'embouchure du sac et activé de sorte que chaque panneau de l'embouchure du sac soit attiré vers le moyen de mise sous vide respectif. Chaque moyen de mise sous vide peut ensuite être déplacé vers le haut et l'embouchure du sac peut être ouverte. Un appareil pour ouvrir un sac est également décrit.
