Description
Die Herstellung der Böden von Papiersäcken, die zur Aufnahme schwerer Stoffe bestimmt sind, geschah bisher meist in der Weise, daß der von der Maschine kommende, auf die erforderliche Länge abgeschnittene, aus kräftigem, einfachem Papier oder mehreren Lagen bestehende, fertig geklebte Schlauch auf entsprechende Länge am einen Ende umgefalzt wurde. Dann mußte der Arbeiter das umgelegte Ende freihändig auseinanderziehen und zu einem Quadrat, flach falten, dessen beide in der Längsrichtung liegende Ecken gegeneinander umgebrochen wurden, worauf erst das etwa rechteckige BodenblattThe manufacture of the bottoms of paper sacks that hold heavy materials are determined, so far mostly happened in such a way that the coming from the machine, Cut to the required length from strong, plain paper or several Lay existing, pre-glued hose to the appropriate length at one end was folded over. Then the worker had to free-hand pull the folded end apart and fold flat into a square, both of which are longitudinally Corners were broken against each other, whereupon the roughly rectangular base sheet
1S aufgeklebt werden "konnte. Man hat bereits versucht, diese umständliche Handarbeit ,auf maschinellem Wege durch besondere, mechanisch bewegte Faltvorrichtungen auszuführen, die an der den Papierschlauch herstellenden Maschine angebracht waren. Diese Einrichtungen erwiesen sich aber besonders bei größeren Abmessungen als sehr kompliziert und aus diesem Grunde auch nicht durchaus zuverlässig. 1 S ". Attempts have already been made to carry out this cumbersome manual work by machine using special, mechanically moved folding devices that were attached to the machine producing the paper tube for this reason not entirely reliable.
Die vorliegende Erfindung betrifft nun ein Verfahren, das eine erhebliche Beschleunigung und Erleichterung gegenüber der früheren, vollständig freihändigen Arbeitsweise herbeiführt, gleichzeitig aber außerordentlich einfach und damit billig auszuführen ist. Das wesentliche Merkmal des neuen Verfahrens besteht in der Anwendung einer der gewünschten Bodenform entsprechenden. Hilfsvorrichtung, die eine fast selbsttätige und dauernd gleichmäßig genaue Faltung des Bodenteiles er-' möglicht.The present invention now relates to a method that significantly speeds up and brings relief compared to the previous, completely freehand working method, but at the same time it is extremely simple and therefore cheap to carry out. The essentials The feature of the new method consists in the application of one of the desired ones Corresponding soil shape. Auxiliary device that is almost automatic and continuously uniform precise folding of the bottom part possible.
Wie die Zeichnung erkennen läßt, wird als Hilfsvorrichtung eine beispielsweise quadratische", dünne aber feste Platte aus Pappe, Holz ο. dgl. (Fig. ι) benutzt, die nach einer Diagonale 1-1 und zwei dazu parallelen Querlinien 2-2, 2'-2' in vier Teile zerlegt ist, die gelenkig derart miteinander verbunden sind, daß sich die Ecken 3, 3' durch Zusammenklappen um 1-1 aufeinanderlegen Und auch durch Umklappen nur um 2-2 und 2'-2' nach der Mitte zusammenlegen lassen. Gemäß der Erfindung wird nun die zu einem Dreieck zusammengelegte Faltschablone in das um die Linie ^1-A1 umgefalzte' Ende des Sackes soweit eingeschoben, bis seine Diagonale 1-1 in den Falz U1-U1 stößt (Fig. 2). Darauf fällt die Schablone zum Quadrat auseinander, wobei der Arbeiter meist nur ein wenig nachzuhelfen braucht. Das Sackende wird dadurch in der gewünschten Weise auseinander gebreitet und nimmt die Form wie in Fig. 3 ersichtlich an, die durch kräftiges Entlangstreifen an den Kanten oder Pressen der gefalteten Ränder U1-U3, ax-u[ dem. Sack eingeprägt wird. Darauf klappt der Arbeiter die Schablone um die Linien 2-2, 2'-2' so um, daß die Zipfel U3, a'a in der Mitte gegenüber liegen und die Falzkanten U2-U2 ■ und ·α'2-α'2 entstehen, die ebenfalls kräftig ausgestrichen werden müssen. Dann kann die Schablone wieder aus dem Sackende herausgenommen werden, und der Boden fällt sofort in-seine Falten wieder wie gewünscht zusammen,, so daß' das Bodenblatt ohne weiteres aufgeklebt werden kann.As the drawing reveals, an example of a square ", thin but solid board made of cardboard, wood ο. Like '-2' is broken down into four parts, which are hinged together in such a way that the corners 3, 3 'lie on top of one another by folding 1-1 and also by folding only 2-2 and 2'-2' towards the middle According to the invention, the folding template, which has been folded into a triangle, is now pushed into the end of the sack folded around the line ^ 1 -A 1 until its diagonal 1-1 pushes into the fold U 1 -U 1 (Fig. The template then falls apart to form a square, whereby the worker usually only needs a little help. The end of the bag is thereby spread apart in the desired manner and takes on the shape as shown in Fig or pressing the folded edges of U 1 -U 3 , a x -u [ dem. Sack is embossed. Then the worker folds the template around the lines 2-2, 2'-2 'so that the tips U 3 , a' a are in the middle opposite and the folded edges U 2 -U 2 ■ and · α ' 2 - α ' 2 arise, which must also be streaked out vigorously. The template can then be taken out of the end of the sack again, and the base immediately collapses into its folds again as desired, so that the base sheet can easily be glued on.
Um die Falten recht dauerhaft zu gestalten,To make the wrinkles quite permanent,
. können die in Frage kommenden Kanten und Knickstellen der Schablone zugeschärft sein, so daß sich das Papier des Sackes sehr scharf um dieselbe kniffen läßt.. the edges and kinks in question on the template can be sharpened so that the paper of the sack can be pinched very sharply around it.
