Abstract

Plastic carrier bags with a closure flap welded to one of its side-walls, an upper front wall that can be pushed under the flap, and carrying handles fastened to the two bag inner walls are produced by (a) forming a sheet into semi-tubular shape, in which are lengthwise edge extends over the other lengthwise edge, (b) intermittently transporting the sheet, (c) making openings in the overlapping part of the wider sheet part, (d) welding carrying handles to the inner faces of the upper and lower sheets, (e) moving the sheet upper and lower parts away from each other, (f) pressing the handle on the long side through the openings, (g) inwardly folding the edge strips of the sheet lower part that is to be from the flap so that the fold edge is situated at about the height of the upper edge of the sheet upper side, (h) making openings or cuts in the sheet upper side, (i) bringing together the sheet upper and lower parts, and (j) sepg. the individual sheet upper and lower parts by cross welds and cuts. Process gives rapid fixing of carrying handles of thicker flexible sheet matl. without difficulties.

Verfahren zur Herstellung von Textiltragetaschen Zusatz zu Patentanmeldung 2 125 421 ) Process for the production of textile carrier bags Addendum to patent application 2 125 421)

Das Hauptpatent bezieht sich auf eine Textil tragetasche aus Kunststoff mit Verschlußklappe, die seitlich mit den Taschenwänden verschweißt ist und mit oben angeschrägter Vorderwand, die als Lasche unter die Verschlußklappe gesteckt werden kann und mit zwei an den beiden Tascheninnenseiten befestigten Tragegriffen sowie mit zwei Verfahrensvarianten zur Herstellung dieser Taschen. The main patent relates to a textile carrier bag made of plastic with closure flap, which is welded to the side of the pocket walls and with a beveled front wall, which acts as a flap under the Closure flap can be inserted and with two handles attached to the two inner sides of the bag and with two process variants for the production of these bags.

Bei einem dieser Verfahren, bei dem die Verschlußklappe durch Umschlagen eines überstehenden Randstreifens der einen Bahnhälfte um die Oberkante der einen Teil der Taschenvorderwand darstellenden Lasche gewonnen wird, liegt als Ergebnis des beschriebenen Verfahrens eine verschlossene Tasche vor, bei der sich die Lasche unter der Klappe befindet und die beiden Tragegriffe durch die Öffnung in der Klappe nach oben ragen. Soll die Tasche befüllt werden, muß die einen Teil der Vorderwand darstellende Lasche zuerst mit daran befestigtem Tragegriff unter der Klappe hervorgezogen werden, damit die Einfüllöffnung zugänglich wird.In one of these methods, in which the flap is turned over a protruding edge strip of one half of the track around the upper edge of the part of the front wall of the bag Tab is obtained, the result of the method described is a closed pocket with the tab underneath the flap and the two handles through the opening in the The flap protrude upwards. If the pocket is to be filled, one of them has to be Part of the front wall showing flap first with attached The handle can be pulled out from under the flap so that the filling opening is accessible.

Um nach Beendigung des Herstellungsvorgangs eine geöffnete, füllbereite Tasche vorliegen zu haben, hat es sich als besonders zweckmäßig gezeigt, in Abwandlung des in der Hauptpatentanmeldung beschriebenen Verfahrens in dem überstehenden Randstreifen der Bahn zunächst Ausstanzungen 8 anzubringen, sodann die Traggriffe 9 einzuschweißen und im Anschluß hieran die Bahn so weiter zu führen, daß zwischen Bahnober- und -Unterseite ein größerer Abstand besteht, während dieses Zustandes den an der Bahnunterseite befindlichen Traggriff durch die Ausstanzung 8 zu drücken, sodann den überstehenden die spätere Klappe bi Idenden Randstreifen in bekannter Weise so nach innen umzufalten, daß die Faltkante sich etwa in Höhe der Oberkante der Bahnoberseite befindet, sodann an der Bahnoberseite Ausstanzungen 5 oder Einschnitte 6 anzubringen, Bahnober- und -UnterseiteIn order to have an opened, ready-to-fill To have a pocket, it has been found to be particularly useful in a modification of the method described in the main patent application first to attach punchings 8 in the protruding edge strip of the web, then to weld in the carrying handles 9 and subsequently to continue to guide the web in such a way that there is a greater distance between the top and bottom of the web, during this state the distance on the underside of the web to press the handle located through the punching 8, then the protruding the later flap bi Idenden edge strips in known Fold inwards in such a way that the folded edge is approximately at the level of the upper edge of the top of the web, then cut-outs on the top of the web 5 or incisions 6 to be made, top and bottom of the web

wieder aufeinanderliegend zusammenzuführen und danach in üblicher Weise durch Querschweißnähte und Trennschnitte die einzelnen Tragetaschen abzutrennen.to be brought together again lying on top of one another and then in the usual way Make the individual carrier bags by means of cross-weld seams and separating cuts to separate.

Bei dieser Verfahrensweise liegt als Ergebnis eine Tragetasche vor, bei der die Verschlußlasche mit einem der beiden Tragegriffe auf der Verschlußklappe liegt und vor dem Befüllen der Tasche nur angehoben zu werden braucht.The result of this procedure is a carrier bag, in which the locking flap with one of the two handles on the Closure flap is and just lifted before filling the bag needs to become.

Als besonders zweckmäßig hat sich ferner die Verwendung von flexiblen Tragegriffen aus dicker Pol ie herausgestellt, wie sie z. B. in der deutschen Auslegeschrift 1 965 626 beschrieben sind,da bei diesen Tragegriffen ohne Schwierigkeiten eine wechselnd horizontale oder vertikale Bahnführung möglich ist, was eine relativ kurze Bauweise der Herstellungsmaschine erlaubt.The use of flexible ones has also proven to be particularly useful Carrying handles made of thick Pol ie pointed out as they are z. B. in the German Auslegeschrift 1 965 626 are described because these handles An alternating horizontal or vertical path guidance is possible without difficulty, which means a relatively short construction of the manufacturing machine permitted.
