Title (EN) BAND OF BAGS,PROCESS AND DEVICE FOR PRODUCING SUCH
(FR) BANDE DE SACHETS, PROCEDE ET DISPOSITIF POUR SA FABRICATION
Abstract: front page image
(EN)The band of bags comprises a hanging band (20) to which the bags are attached by means of hanging sections (24). Slits (30) are cut into the hanging sections (24) at the rear edges there of with respect to the feed direction in the filling device. These slits (30) make the inflation of the bags (22) easier by means of an air jet directed substantially to the bags plane against their filling openings. To initiate the separation of the front wall of the bags, at the free end of this front wall of the bags, additional openings (18) can be provided through which an air jet can be directed perpendicularly to the front wall of the bags. To increase the traverse zone (W) where the bags (22) can be separated from the hanging band (20) by means of a slit parallel to the feed direction, the slits (30) can be provided with a substantially transverse cut (30a) which extends transversally outwards from the inner end of the slits (30).
(FR)La bande de sachets comprend une bande de suspension (20) a laquelle les sachets (22) sont fixes au moyen de troncons de suspension (24). Des fentes (30) sont pratiquees dans les troncons de suspension (24) a leurs bords arrieres par rapport a la direction d"avance dans le dispositif de remplissage. Ces fentes (30) facilitent le gonflage des sachets (22) au moyen d"un jet d"air dirige principalement dans le plan des sachets contre leurs ouvertures de remplissage. Pour amorcer la separation de la paroi avant des sachets on peut prevoir, a la hauteur du bout libre de cette paroi avant, les ouvertures supplementaires (18) a travers lesquelles on peut diriger un jet d"air perpendiculairement a la paroi avant des sachets. Pour augmenter la zone transversale (W) dans laquelle les sachets (22) peuvent etre separes de la bande de suspension (20) au moyen d"une fente parallele a la direction d"avance, on peut munir les fentes (30) d"une coupure essentiellement transversale (30a) qui s"etend transversalement vers l"exterieur a partir de l"extremite interieure des fentes (30).
