Title (EN) VALVE BAG AND METHOD AND SYSTEM FOR PRODUCING A VALVE BAG
(FR) SAC À VALVE AINSI QUE PROCÉDÉ ET SYSTÈME DE FABRICATION D’UN SAC À VALVE
(DE) VENTILSACK SOWIE VERFAHREN UND SYSTEM ZUR HERSTELLUNG EINES VENTILSACKS
Abstract:
(EN) The invention relates to a valve bag, in particular a cross-bottom valve bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which bound a bag interior, comprising a valve, which is arranged in one of the bottoms and via which the bag interior can be filled with a filling material, and comprising venting openings in the first and/or in the second wall for venting the bag interior. At least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed at least by two parallel fastening strips and by a cover strip, the cover strip likewise comprising venting openings. The shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall, or the cover strip and/or the parallel fastening strips consist of stretchable material.
(FR) L’invention concerne un sac à valve, en particulier un sac à valve à fonds croisés, comprenant une première paroi et une seconde paroi qui sont reliées l’une à l’autre par des bords latéraux ou des pliages latéraux ainsi que par des fonds et qui définissent un espace intérieur de sac, une valve agencée dans un des fonds et par laquelle l’espace intérieur de sac peut être rempli d’un produit de remplissage, ainsi que des ouvertures de mise à l’air libre ménagées dans la première et/ou dans la seconde paroi pour la mise à l’air libre de l’espace intérieur du sac. Sur la face extérieure d’au moins une paroi est ménagé au moins un canal qui recouvre les ouvertures de mise à l’air libre et qui est formé par au moins deux bandes de fixation parallèles et une bande de recouvrement, la bande de recouvrement comprend également des ouvertures de mise à l’air libre, et la distance la plus courte entre les bandes de fixation parallèles le long de la bande de recouvrement est plus longue que la distance la plus courte le long de la ou des parois ou de la bande de recouvrement et/ou les bandes de fixation parallèles sont composées d’un matériau extensible.
(DE) Die Erfindung beschreibt einen Ventilsack, insbesondere Kreuzbodenventilsack, umfassend eine erste Wand und eine zweite Wand, welche durch Seitenkanten oder Seitenfalten sowie durch Böden miteinander verbunden sind und einen Sackinnenraum begrenzen, ein in einem der Böden angeordneten Ventil, über welches der Sackinnenraum mit einem Füllgut befüllbar ist, sowie Entlüftungsöffnungen in der ersten und/oder in der zweiten Wand zur Entlüftung des Sackinnenraums. An der Außenseite zumindest einer Wand ist wenigstens ein Kanal vorgesehen, welcher die Entlüftungsöffnungen überdeckt und welcher wenigstens durch zwei parallele Befestigungsstreifen und einem Überdeckungsstreifen gebildet ist, der Überdeckungsstreifen ebenfalls Entlüftungsöffnungen umfasst und wobei der kürzeste Weg zwischen den parallelen Befestigungsstreifen entlang des Überdeckungsstreifens länger ist als der kürzeste Weg entlang der zumindest einen Wand oder der Überdeckungsstreifen und/oder die parallelen Befestigungsstreifen aus dehnbarem Material bestehen.
