Description
Die Erfindung betrifft ein Verfahren zum Hersteilen von Beuteln nach dem Gattungsbegriff des Patentanspruchs 1.The invention relates to a method for producing bags according to the preamble of the claim 1.
Bei einem aus der DE-OS 19 00 337 bekannten Verfahren dieser Art werden die Öffnuiigsränder von HaIbschlauchbahnen, die durch einen mittigen Längsschnitt aus einer Schlauchbahn gebildet worden sind, zur Schaffung von verstärkten Griffbereichen auf die angrenzenden Beutelwandungen umgeschlagen. Die durch die umgeschlagenen Öffnungsränder gebildeten Verstärkungsslreifen erstrecken sich jedoch über die gesamte Beutelbreite und verstärken somit die oberen Öffnungsränder auch außerhalb der Griffbereiche, in denen keine Verstärkung erforderlich ist, so daß unnötig viel verstärkendes Folienmaterial verwendet wird.In a method known from DE-OS 19 00 337 in this way the edges of the opening of half-tube sheets, which have been formed by a central longitudinal cut from a hose web to create folded over from reinforced grip areas to the adjacent bag walls. The ones turned over by the However, reinforcement strips formed at the edges of the opening extend over the entire width of the bag and thus reinforce the upper edges of the opening even outside the grip areas in which there is no reinforcement is required, so that an unnecessarily large amount of reinforcing sheet material is used.
Aufgabe der Erfindung ist es daher, das bekannte Verfahren dadurch zu verbessern, daß bei guter Grifflochverstärkung Folienmaterial eingespart wird.The object of the invention is therefore to improve the known method in that with good grip hole reinforcement Foil material is saved.
Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.
Das erfindungsgemäße Verfahren benötigt bei guter Grifflochverstärkung nur etwa die Hälfte der Menge an verstärkendem Folienmaterial, die bei dem bekannten Verfahren verwendet wurde.The method according to the invention requires only about half the amount with good grip hole reinforcement reinforcing sheet material used in the known method.
Aus der DE-AS 12 44 547 ist es an sich bekannt, eine Schlauchbahn durch eine wellenförmige Schnittlinie in Halbschlauchbahnen zu trennen, so daß über die Beutelränder überstehende Lappen geschaffen werden, in die die Grifflöcher eingestanzt werden, wobei die Außenkontur der Lappen gleichzeitig die Außenkontur der Handgriffe bilden. Durch nur in die überstehenden Lappen gestanzte Grifföffnungen werden jedoch Handgriffe geschaffen, die bei größerer Belastung infolge schwererer Füllung des Beutels zum Ausreißen neigen.From DE-AS 12 44 54 7 it is known per se to separate a tubular web by a wave-shaped cutting line in semi-tubular webs, so that protruding flaps are created over the bag edges into which the handle holes are punched, the outer contour of the flaps at the same time Form the outer contour of the handles. Handle openings punched only into the protruding tabs, however, create handles which tend to tear out when the bag is heavily loaded due to the heavier filling of the bag.
