Description

Vorrichtung zum Einlegen von Papierabschnitten u. dgl. zwischen für die Herstellung von Papiersäcken dienende, nach dem Zusammenführen zu einer Lagenschicht abzulängende Papierbahnen, und auf dieser Vorrichtung angefertigter mehrlagiger Papiersack Die Erfindung betrifft eine Vorrichtung zum Einlegen von Papierabschnitten u. dgl. zwischen für die Herstellung von Papiersäcken dienende, nach dem Zusammenführen zu einer Lagenschicht abzulängende Papierbahnen, und einen auf dieser Vorrichtung angefertigten mehrlagigen Papiersack. Es ist in der Papierverarbeitung bekannt, in Papierbahnen, die zu einer Lagenschicht zusammengeführt werden, mittels Schwächungslinien ein Vortrennen vorzunehmen und dann die Lagenschicht abzureißen. Auch hat man bereits zwischen zusammenlaufende Papierbahnen Einlagen eingleiten lassen, deren Länge geringer ist als die des hernach abzulängenden Schichtabschnittes.Device for inserting pieces of paper and the like between for used for the production of paper sacks after they have been brought together to form a layer of layers Paper webs to be cut to length, and multilayered sheets made on this device Paper sack The invention relates to a device for inserting paper sections and the like between serving for the production of paper sacks after the merging paper webs to be cut to form a layer of paper, and one on this device made multi-layer paper sack. It is known in paper processing in paper webs, which are brought together to form a layer, by means of weakening lines make a pre-separation and then tear off the layer. Also one already has between converging paper webs insert inserts, the length of which is shorter is than that of the layer section to be cut afterwards.

Die Erfindung verfolgt das Ziel, derartige Lagen so einzulegen, daß die quer über die Bahnenschicht verlaufenden Ränder der Einlagen beiderseits von der Ablängungsschnittkante des Abschnittes einen Abstand aufweisen, damit die Endteile der Schichtabschnitte eine kleinere Lagenzahl erhalten als die Mittelteile. Dadurch soll in einfacher Weise das Vernähen oder Falten von Kreuzböden an den Schichtenden erleichtert und unter Papierersparnis eine Vermehrung der Lagenzahl im Mittelteil des fertigen Sackes erreicht werden, weil hier die Gefahr eines Aufplatzens des gefüllten Sackes am größten ist. Zu diesem Zweck wird gemäß der Erfindung die zur Bildung der Einlagen dienende Bahn langsamer als die anderen Bahnen von ihrer Vorratsrolle abgezogen und die Abschnitte mittels einer Vortrenneinrichtung vorgetrennt und dann durch den schnelleren Vorschub der sich zusammenschließenden Bahnen abgerissen. Man hat ein solches Arbeiten bisher angesichts der hohen Bahngeschwindigkeiten bei der maschinellen Fertigung und wegen der großen Abmessungen der Werkstücke und der mangelnden Steifigkeit des verwendeten Papieres nicht für möglich gehalten.The aim of the invention is to insert such layers in such a way that the edges of the inlays running across the sheet layer on both sides of the cut to length edge of the section have a distance so that the end parts the layer sections receive a smaller number of layers than the middle parts. Through this is intended to be a simple way of sewing or folding cross bottoms at the ends of the layers facilitates an increase in the number of layers in the middle part while saving paper of the finished sack because there is a risk of the filled sack is largest. For this purpose, according to the invention, the for Formation of the web serving the deposits slower than the other webs from their supply roll peeled off and the sections pre-separated by means of a pre-cutting device and then torn off by the faster advance of the joining webs. Such work has hitherto been carried out in view of the high web speeds the machine production and because of the large dimensions of the workpieces and the lack of rigidity of the paper used was not considered possible.

Gegen die Herstellung solcher sogenannter »Bauchbindensäcke« auf den üblichen Maschinen bestand somit bisher ein Vorurteil, weshalb bereits andere Mittel und Maßnahmen vorgeschlagen wurden.Against the production of such so-called "tummy tucks" on the so far there has been a prejudice with conventional machines, which is why other means have been used and actions have been proposed.

Der Erfinder hat festgestellt, daß dieses Vorurteil unberechtigt gewesen ist, daß es vielmehr bei sorgfältiger Bauausführung der Vorrichtungen und richtiger Abstimmung der Fördergeschwindigkeiten von Bahnen und Abschnitten zueinander sehr wohl gelingt, die Abschnitte mit Sicherheit in der gewünschten Lage in die Balinenschicht einzufügen. In der Auswertung dieser Feststellung besteht die Erfindung, und sie ergibt den Vorteil, ein rein maschinelles Herstellen solcher Papiersäcke auf den bisher gebräuchlichen Maschinen zu ermöglichen.The inventor found that this prejudice was unjustified is that it is rather with careful construction of the devices and more correctly Coordination of the conveyor speeds of tracks and sections to each other very much The sections are probably successful in the desired position in the Balinenschicht to insert. In evaluating this finding, the invention consists, and they gives the advantage of a purely machine production of such paper sacks on the to enable previously used machines.

Die Zeichnung stellt schematisch eine Anlage zur Durchführung der vorbeschriebenen Herstellung dar und zeigt in Abb. 1 eine Vorrichtung zum Herstellen von Schlauchabschnitten aus Papierbahnen, Abb.2 einen auf dieser Vorrichtung hergestellten Kreuzbodenventilsack im Längsschnitt.The drawing shows schematically a system for carrying out the production described above and shows in Fig. 1 a device for production of tube sections from paper webs, Fig.2 one produced on this device Cross-bottom valve bag in longitudinal section.

In einem Gestell 10 (Abb. 1) sind Papierrollen 11, 12, 13 und 14 gelagert, von denen Bahnen nach einer Vereinigungsstelle zwischen den Walzen 15, 16 abgezogen werden. Von den Rollen 11, 12 und 14 werden die Bahnen dabei von den Walzen 15, 16 selbst abgezogen, während zum Abziehen der Bahn von der Rolle 13 das langsamer laufende Walzenpaar 17 vorgesehen ist. Dieses Walzenpaar 17 fördert die von der Rolle 13 kommende Bahn durch einen umlaufenden Ouerschneider 18, der sie zu Stücken von kleinerer Länge als der beabsichtigten Sacklänge vortrennt. Ein Walzenpaar 19 bringt diese Abschnitte dann zwischen die Walzen 15 und 16.Paper rolls 11, 12, 13 and 14 are stored in a frame 10 (Fig. 1), from which webs are drawn off after a union point between the rollers 15, 16 will. From the rollers 11, 12 and 14, the webs are thereby driven by the rollers 15, 16 withdrawn itself, while to withdraw the web from the roll 13 the slower running roller pair 17 is provided. This pair of rollers 17 promotes the Roll 13 coming web through a revolving Ouerschneider 18, which they into pieces of a shorter length than the intended length of the sack. A pair of rollers 19 then brings these sections between rollers 15 and 16.

Die Bahnenschicht wird nun in hier nicht dargestellter, bekannter Weise weitergeschoben, zu einem mehrlagigen Schlauch zusammengefaltet, und geht dann wiederum durch einen umlaufenden Querschneider, der die Schlauchabschnitte ablängt, welche an ihren Enden vernäht oder zu Kreuzböden aufgezogen werden. Hierbei geschieht das Ablängen in diesem zweiten Querschneider stets derart, daß der Schnitt etwa in der Mitte zwischen zwei aufeinanderfolgenden Einlagen erfolgt. Diese haben, da sie kürzer sind als die Sacklänge, somit von jeder Schnittkante eines Schlauchabschnittes Abstand.The track layer is now known in not shown here Pushed it further, folded it into a multi-layered tube, and left then in turn by a rotating cross cutter, which the hose sections cut to length, which are sewn at their ends or pulled up to form cross bottoms will. The cutting to length in this second cross cutter is always done in such a way that the cut is made approximately in the middle between two consecutive deposits. Since they are shorter than the length of the sack, they have from every cutting edge of a hose section distance.

Die Lage der Einlagen bei einem so hergestellten Sack ist aus Abb.2 ersichtlich. Die beiden äußeren Sacklagen A und B sowie die innerste Sacklage D erstrecken sich bis in die an beiden Enden des Schlauchabschnittes gebildeten Kreuzböden. (Der besseren Klarheit wegen sind die 1Jbereinanderschlagungen der Bodenklappen nicht gezeichnet.) Die zweitinnerste Lage C hingegen, die in der oben beschriebenen Weise eingelegt ist, reicht beiderseits nur bis nahe an die Böden heran. Die Einlagen können auch bedeutend geringere Breite in Sacklängsrichtung haben, so daß sie nur bindenartig um den Sack herumgelegt sind. Sind dabei mehrere Einlagen angebracht, die etwa zwischen verschiedenen Sackwandbahnen liegen, dann können diese Einlagen vorteilhaft gegeneinander versetzt werden. Die Erfindung ist besonders vorteilhaft, wenn bei den Säcken gekrepptes Papier verwendet wird, das sich unter der Beanspruchung beim Füllen des Sackes zu dehnen vermag, weil besonders in solchen Fällen derartige Einlagen vorzugsweise günstig sind. Zwischen die einzelnen Bahnen kann in an sich bekannter Weise vor dem Zusammenfügen Klebstoff eingetragen werden, gegebenenfalls nur stellenweise.The position of the inlays in a sack manufactured in this way can be seen in Fig. The two outer bag layers A and B and the innermost bag layer D extend into the cross bottoms formed at both ends of the tube section. (For the sake of clarity, the overlapping of the bottom flaps are not shown.) The second innermost layer C, on the other hand, which is inserted in the manner described above, only reaches close to the bottom on both sides. The inserts can also have a significantly smaller width in the longitudinal direction of the sack, so that they are only wrapped around the sack like a bandage. If several inserts are attached, which lie between different blind wall webs, then these inserts can advantageously be offset from one another. The invention is particularly advantageous if creped paper is used in the sacks, which is capable of stretching under the stress when the sack is filled, because such inserts are preferably advantageous particularly in such cases. Adhesive can be introduced between the individual webs in a manner known per se prior to joining, if necessary only in places.
