Abstract

Die Erfindung beschreibt ein Verfahren und eine Vorrichtung zum kontinuierlichen Herstellen von Packsäcken aus einer Folienschlauchbahn aus thermoplastischem Kunststoff, bei dem kontinuierlich ein reißfestes Verschlußband (7) in Längs­ erstreckung entlang einer für das Bilden der Sacköffnung bestimmten Seitenkante der Schlauchbahn mit mindestens einer Schlauchbahnseite haftfest verbunden wird und parallel un­ mittelbar neben dem haftfest aufgebrachten Verschlußband innenliegend verlaufend mindestens eine Schlauchbahnseite mit einer Perforationslinie (8) ausgebildet wird und dann die Schlauchbahn rapportmäßig quer und/oder kontinuierlich längs geschweißt und wahlweise die Schweißnähte getrennt bzw. neben den Schweißnähten abgeschnitten wird, wodurch Säcke (10) mit Seitennaht und/oder Bodennaht erhalten werden, die mit einem längs der Sacköffnung (12) abreißbarem Verschluß­ band ausgerüstet sind und die Säcke ggf. nach Faltung in Sackpacken gestapelt und zu Displayverpackungen abgepackt werden . The invention describes a method and an apparatus for the continuous production of pack sacks from one Foil tube sheet made of thermoplastic, at the continuously a tear-resistant fastener tape (7) in the longitudinal direction extension along one for forming the bag opening certain side edge of the tube sheet with at least one Hose track side is firmly connected and parallel un indirectly next to the adhesive tape at least one side of the hose runs inside is formed with a perforation line (8) and then the tubular track is repeated transversely and / or continuously welded lengthways and optionally the weld seams separated or next to the welds is cut off, creating sacks (10) with side seam and / or bottom seam that can be obtained with a closure that can be torn off along the pocket opening (12) are equipped and the bags, if necessary, after being folded in Sack packs stacked and packed into display packaging will .
