Claims: 1. Method for producing unfolded sections from a zigzag folded and zigzag stacked sheet of paper, Cellulose, fiber tiles or the like, d a d u r c h g e - indicates that the folds cut off at the two edge parts of the stack immediately after folding will.

2. Vorrichtung zur Durchführung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, daß einer Zickzackfaltmaschine zwei parallel zueinander angeordnete Bandmesser (6 a, 6 b) nachgeschaltet sind, deren paralleler Abstand kleiner ist als die Breite des Stapels (8 a). 2. Apparatus for performing the method according to claim 1, characterized characterized in that a zigzag folding machine has two parallel to each other Band knives (6 a, 6 b) are connected downstream, the parallel spacing of which is smaller than the width of the stack (8 a).

Die Erfindung betrifft ein Verfahren zur Herstellung von ungefalteten Abschnitten aus einer zickzackförmig gefalteten und zickzackförmig gestapelten Bahn aus Papier, Zellstoff, Faserfliesen oder ähnlichen Materialien, sowie eine Vorrichtung zur Durchführung des Verfahrens. The invention relates to a method for producing unfolded Sections of a sheet folded in a zigzag and stacked in a zigzag made of paper, cellulose, fiber tiles or similar materials, as well as a device to carry out the procedure.

Es ist bekannt, beispielsweise bei der Herstellung von Papiertaschentüchern oder Papierservietten, eine Materialbahn zickzackförmig zu falten und nach dem Falten in der Mitte durchzuschneiden, so daß Einzelstücke entstehen, die einmal gefaltet sind. Bei größeren Einzelstücken, wie beispielsweise Sets oder Tischdecken, die beim Gebrauch auf eine glatte Unterlage ausgebreitet werden sollen und dort glatt aufliegen sollen, erweist sich diese Falte häufig als unschön und störend. It is known, for example, in the manufacture of paper handkerchiefs or paper napkins, to fold a sheet of material in a zigzag and after folding cut through in the middle so that individual pieces are created that are folded once are. For larger individual items, such as sets or tablecloths, the should be spread out on a smooth surface when in use and smooth there should rest, this fold often turns out to be unsightly and annoying.

Es ist weiterhin bekannt, größere Bogen, beispielsweise Tischdecken, in der Weise herzustellen, daß die einzelnen Stücke von einer Papierbahn laufend abgezogen und mittels eines Querschneiders abgetrennt werden. Dieses Verfahren ist aber nicht bei allen gewünschten Materialien brauchbar. Bei sehr weichem Material, beispielsweise Zellstoff, ist das Verfahren nicht oder nur mit sehr niedrigen Herstellungsgeschwindigkeiten durchführbar. It is also known to use larger sheets, for example tablecloths, to produce in such a way that the individual pieces of a paper web running peeled off and cut off by means of a cross cutter. This procedure is but not usable with all desired materials. With very soft material, For example, pulp, the process is not or only at very low production speeds feasible.

Die der Erfindung zu Grunde liegende Aufgabe bestand darin, ein Verfahren der eingangs genannten Art zu schaffen, mit dem auch größere Abschnitte aus Materialien sehr verschiedener Art, beispielsweise Tischtücher, Handtücher usw., mit hoher Erzeugungsgeschwindigkeit hergestellt werden können, wobei das entstehende Produkt aus ungefalteten Abschnitten bestehen soll. The object on which the invention is based was to develop a method of the type mentioned to create, with which also larger sections of materials of very different types, for example tablecloths, towels, etc., with high production speeds can be made with the resulting product made up of unfolded sections should exist.

Die Lösung dieser Aufgabe geschieht erfindungsgemäß dadurch, daß die Falten an den beiden Randpartien des Stapels unmittelbar nach dem Falten abgeschnitten werden. This object is achieved according to the invention in that cut off the folds on the two edge parts of the stack immediately after folding will.

Der Stapel besteht dann nach dem Abschneiden der Randpartien aus einzelnen ungefalteten Abschnitten. The stack then consists of after cutting off the edge parts individual unfolded sections.

Gegenstand der Erfindung ist weiterhin eine Vorrichtung zur Durchführung des obengenannten Verfahrens. Erfindungsgemäß ist die Vorrichtung dadurch gekennzeichnet, daß einer Zickzackfaltmaschine zwei parallel zueinander angeordnete Bandmesser nachgeschaltet sind, deren paralleler Abstand kleiner ist als die Breite des Stapels. The invention also relates to a device for implementation the above procedure. According to the invention, the device is characterized in that that a zigzag folding machine is followed by two band knives arranged parallel to one another whose parallel spacing is smaller than the width of the stack.

Zickzackfaltmaschinen als solche sind an sich bekannt. Eine bekannte Zickzackfaltmaschine wird beispielsweise in der deutschen Patentschrift 636 666 beschrieben. Durch die Kombination der Zickzackfaltmaschine mit den Bandmessern in der oben angegebenen Weise wird eine besonders einfache Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens erhalten. Zigzag folding machines as such are known per se. An acquaintance Zigzag folding machine is for example in the German patent specification 636 666 described. By combining the zigzag folding machine with the band knives in the manner indicated above is a particularly simple device for implementation obtained by the method according to the invention.

Im folgenden wird an Hand der Zeichnung ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung näher erläutert. In the following, an exemplary embodiment of the device according to the invention explained in more detail.

In der Zeichnung sind in perspektivischer, stark schematisierter Darstellung die wichtigsten Teile einer Vorrichtung zur Herstellung von ungefalteten Abschnitten aus einer Bahn dargestellt. In the drawing are in perspective, highly schematic Representation of the most important parts of a device for the production of unfolded Sections of a web shown.

Die Bahn 2 wird von einer um eine waagerechte Achse laufenden Rolle 1 abgewickelt. Sie kann ein-oder mehrlagig sein und durchläuft zunächst eine aus drei Richtstangen bestehende Wendestation 3, wobei sie aus einer horizontalen in eine vertikale Ebene gedreht wird. Es können bis zu dieser Stelle noch weitere, der Einfachheit halber nicht dargestellte bekannte Vorrichtungen, wie eine Druckmaschine, ein Prägekalander usw., vorgeschaltet sein. The web 2 is from a roll running around a horizontal axis 1 settled. It can be single or multi-layer and first passes through one three straightening rods existing turning station 3, whereby it consists of a horizontal in a vertical plane is rotated. Up to this point there can be more, known devices, not shown for the sake of simplicity, such as a printing machine, an embossing calender, etc., be connected upstream.

Die in die vertikale Ebene gedrehte Bahn 2 durchläuft dann eine Zugpartie 4, die aus zwei zu beiden Seiten der Bahn angeordneten im gegenläufigen Sinne rotierenden Walzen besteht und die so angeordnet ist, daß das Band nicht nach unten ausweichen kann. The web 2 rotated in the vertical plane then passes through a train section 4, which consist of two rotating in opposite directions arranged on both sides of the web Rolls consists and which is arranged so that the tape does not give way down can.
