Description

Verfahren zum fortlaufenden Herstellen von Seitennahtbeuteln mit Bodenfalte Es ist ein Verfahren zum fortlaufenden Herstellen von Beuteln bekannt, hei dein mau eine Folienbahn aus schweißbarem Kunststoff unter Einschlagen einer Längsfalte zwischen die beiden Lagen der Länge nach doppelt legt, in gewissen Abständen quer zur Folienbahn verschweißt und darauf durch Schnitte, welche der Länge nach durch die Schweißnähte gehen, in Beutel zerlegt. 1-lall erhält dabei Beutel mit einer Schweißnaht an jeder Seite und mit einer beuteleinwärts geschlagenen Falte am Beutelboden. Es ist weiter ein Verfahren zum fortlaufenden Herstellen voll Beuteln bekannt, bei welchem null eine Folienbahn aus schweißharem Kunststoff unter Einschlagen je einer Falte an den Rändern zwischen die beiden Lagen der Folienbahn doppelt legt, daraus durch Legen voll Schweißnähten quer zur Folienbalin und Zerlegen der Folienbahri durch Schnitte, welche der Länge nach durch die Schweißnähte gehen, aus zwei zusammenhängenden Beuteln bestellende Abschnitte herstellt und diese dann unter Bildung von je zwei Beuteln durchtrennt.Process for the continuous production of side-seam bags with a bottom gusset A method of continuously making bags is known, called yours mau a sheet of film made of weldable plastic with a longitudinal fold Lay twice lengthways between the two layers, at certain intervals across welded to the film web and then through cuts that go through the length the welds go, disassembled into bags. 1-lall receives a bag with a Weld seam on each side and with a fold in the bag at the bottom of the bag. There is also known a method of continuously manufacturing full bags which zero a sheet of plastic that is hard to weld, wrapping one each Fold twice at the edges between the two layers of the film, from it by laying fully welded seams across the foil and dismantling the foil by cuts, which go through the length of the weld seams, from two contiguous Sections ordering bags and then making two Severed bags.

Die vorstehend genannten Verfahren sind mit sehr weichen Folien, wie beispielsweise solchen aus Polyäthylen, nicht ohne weiteres durchführbar, da es nur mit großer Mühe gelingt, eitle Polyäthylenfolie unter Einscb:lagen voll Falten gleichmäßig doppelt zu legen, so daß dieses Verfahren praktisch kaum fortlaufend durchführbar ist.The above methods are with very soft foils, such as for example those made of polyethylene, not easily feasible because it Only with great effort succeeds, vain polyethylene film under cover lay full of folds to be evenly doubled, so that this process is practically hardly continuous is feasible.

Wie nun geftin,den wurde, erhält man auf einfache Weise Polyiitliylthlilretttel mit b euteleinwärts geschlagener Bodenfalte und Seitennähten, indem man einett nahtlosen Seitenfaltelischlauch aus Polyäthylen quer zur Scilauchballn in gewissen Abständen verschweißt und mittels der Länge nach durch die Schweißnähte gehender Schnitte und eines in Transportrichtung der Schlauchbahn gehenden Schnittes durchtrenlit.As has now been shown, one can easily obtain polyamide tablets with bottom pleat turned inside the bag and side seams by making a seamless Gusseted hose made of polyethylene across the scilauchballn at certain intervals welded and by means of cuts going lengthwise through the weld seams and a cut going in the transport direction of the hose web.

Die zum Herstellen der Beutel nach der 1-,Erfindung als Ausgangsmaterial dienenden nahtlosen mit Seitenfalten versehenen Schläuche aus Polyäthylen w.erdeu in technischem -Maßstab hergestellt und sind Handelsware.The one for producing the bags according to the 1, invention as the starting material serving seamless gusseted hoses made of polyethylene w.erdeu Manufactured on a technical scale and are commodities.

Das folgende Beispiel erläutert unter Bezugnahme auf die Zeichnung das Verfahren. Ein voll <lerRolle F: ablaufender mit Seitenfalten 2 versehener flachliegender Schlauch 1 aus Polyäthylen wird in regelmäßigen Abständen quer zur Schlauchba'h-n zugeschweißt und durch Schnitte 4, welche der Länge nach durch die Schweißnähte 3 gehen, in beiderseits verschlossene Alischaltte 5 des Seitenfaltenschlauchs zerlegt. und diese werden dann durch längs der ehemaligen Sehlauchbahii geführte Schnitte 6 in zwei Beutel 7 zerlegt. Die erhaltenen ftachliegendeli Beutel 7 sind so kroch. wie die halbe Breite der Seitenfaltenschlauchbahn 1 und so breit wie der Abstand der Schweißnähte 3 voneinander. Am Boden haben s.ie eine beuteleinwärts liegende Falte voll der Tiefe der Seitenfalten 2 des verarbeiteten Polyäthylenschlauchs 1. Beim Füllen der Beutel bildet sich ein rechteckiger Beutelboden aus. Die Breite des Beutelbodens entspricht - sieht ntan voll dem für die Seitennähte verbrauchten Material ab - der Breite des flachliegenden Beutels vermindert uni die doppelte Bodenfaltentiefe, die Tiefe des- Beutelbodens entspricht der doppelten Bodenfaltentiefe. Die Höhe des gefüllten Beutels ist dieselbe wie die des flachliegenden. Durch eiltsprechende Wahl der Breite des verarbeiteten Polyäthylen-SeitenfaItelischlauchs, der Tiefe seiner Seitenfalten und des Abstandes der Schweißnähte ist man in der Lage. Beutel verschiedener Abmessungen herzustellen.. Geht man beim vorstehenden Beispiel von einem Polyäthylen-Seitenfaltensdhla.ueli 1 voll 30 cm Breite, ohne die Seitenfalten 2 gemessen, und. mit 3 cm tiefen Seitenfalten 2 aus und legt man die Schweißnähte 3 in Abständen von 16 cm, so erhält man 16 cm breite und 15 cm hohe flachliegende Beutel, die beim Füllen einen rechteckigen Boden von 6 cm Tiefe und etwa 10 cm Breite ausbilden.The following example explains with reference to the drawing the procedure. A full roll F: running out with gusseted 2 Flat lying hose 1 made of polyethylene is at regular intervals across the Hose brackets are welded shut and cut through 4 cuts lengthways through the Weld seams 3 go into double-sided closed aluminum switches 5 of the side-gusseted tube disassembled. and these are then guided along the former Sehlauchbahii Sections 6 broken down into two bags 7. The obtained ftachliegendeli bags 7 are so crawled. as half the width of the gusseted tubular web 1 and as wide as that Distance of the weld seams 3 from one another. They have one inside the bag on the bottom lying fold full of the depth of the side folds 2 of the processed polyethylene tube 1. When the bag is filled, a rectangular bottom of the bag is formed. The width of the bottom of the bag corresponds to that used for the side seams Material from - the width of the flat bag reduces uni doubled Bottom fold depth, the depth of the bag bottom corresponds to twice the bottom fold depth. The height of the filled bag is the same as that of the flat one. By urgent Choice of the width of the processed polyethylene side-fold hose, the depth its gussets and the distance between the welds one is able to. bag different dimensions .. If one goes in the previous example of a polyethylene gusset dhla.ueli 1 full 30 cm wide, without the gussets 2 measured, and. with 3 cm deep gussets 2 and place the weld seams 3 at intervals of 16 cm, you get 16 cm wide and 15 cm high lying flat Bags which, when filled, have a rectangular bottom 6 cm deep and about 10 cm wide form.

Das Verfalhren ist von größter Einfachheit und läßt sich nach nur geringfügigen Änderungen all den Maschinen, die man üblicherweise zur Herstellung von Seitenfaltenbeuteln aus Seitenfaltenschläuch.en verwendet, mit diesen Maschinen ausführen. Es hat gegenüber der bisher bekannten Verfahrensweise für die Herstellung von Seiten.nahtbeuteln mit Bodenfalte den Vorteil, daß auch Betriehe, die tiur mit einfach zti handhabenden Maschinen arbeiten, diese sehr vorteilhafte Beutelart aus Polyäthylenmaterial herzustellen in der Lage sind. Ein weiterer Vorteil besteht darin, daß es bei dem Verfahren. keine Schwierigkeiten macht, bedruckte Beutel herzustellen.The procedure is of the greatest simplicity and can only be followed minor changes to all of the machines that are commonly used to manufacture of gusseted bags made from gusseted tubes used with these machines carry out. It has compared to the previously known procedure for the production Side seam bags with a bottom fold have the advantage that they can also be used with easy zti handling machines work out this very advantageous bag type Are able to manufacture polyethylene material. Another advantage consists in that it is in the process. makes no difficulty in making printed bags.
