Längs eines Tisches 1 werden Papierbögen! mit Hilfe von Transportwalzen 55, 12, 42 in Richtung des Pfeiles 3 durch die Maschine bewegt. Oberhalb des Tisches 1 ist eine Quetschwalze 4 vorgesehen, welche eine Riffelung trägt. Die Quetschwalze 4 berührt eine Übertragungswalze 5, welche schwache, jedoch relativ breite Erhebungen 6 aufweist. Auf den Erhebungen laufen Ringscheiben 7 einer Sireifenwalze 8. Die Ringscheiben berühren von Vorratsrollen 10 abgezogene Papierstreifen 9. die um eine Walze 11 laufen. Eine Walze 12 drückt die Papierstreifen auf die durchlaufenden Bögen 2. In den Keil oberhalb der Beriihrungslinie A-A der Quetschwalze 4 und der Übertragungswalze 5 wird mit Hilfe einer Düse 13 laufend Klebstoff 14 eingefüllt. Die Quetschwalze 4 und die Übertragungswalze 5 drehen sich derart, daß sie trachten, den Klebstoff in den Keil zu drücken. Hierbei verteilt die Quetschwalze 4 den Klebstoff über die gesamte Länge der Übertragungswalze 5, und die Erhebungen 6 werden mit Klebstoff beschichtet, so daß sich ein Klebstoffilm auf den Erhebungen bildet. Dieser Klebstoff wird von den Rändern der Ringscheiben 7 abgenommen und als schmaler Streifen auf die Papierbänder 9 übertragen. Weitere nicht dargestellte Walzen sargen für den Weitertransport der Bögen 2 und den Andruck der Streifen 9.Along a table 1 are sheets of paper! moved through the machine in the direction of arrow 3 with the aid of transport rollers 55, 12, 42. A squeegee roller 4 is provided above the table 1 and has a corrugation. The squeegee roller 4 contacts a transfer roller 5 which has weak but relatively wide elevations 6. Ring disks 7 of a tire roller 8 run on the elevations. The ring disks touch paper strips 9 drawn off from supply rolls 10, which run around a roller 11. A roller 12 presses the paper strips onto the sheets 2 passing through . Adhesive 14 is continuously poured into the wedge above the line of contact AA of the squeegee roller 4 and the transfer roller 5 with the aid of a nozzle 13. The nip roller 4 and the transfer roller 5 rotate so that they tend to force the adhesive into the wedge. Here, the nip roller 4 distributes the adhesive over the entire length of the transfer roller 5, and the elevations 6 are coated with adhesive, so that an adhesive film is formed on the elevations. This adhesive is removed from the edges of the annular disks 7 and transferred to the paper tapes 9 as a narrow strip. Further rollers, not shown, coffin for the further transport of the sheets 2 and the pressure of the strips 9.

Die Düse 13 ist mit einem Vorratsbehälter 15 verbunden, der durch einen Kolben 16 nach obin luftdicht abgeschlossen ist. Oberhalb des Kolbens 16 wird im Raum 17 ein Überdruck erzeugt, so daß ständig über das Rohr 18 Klebstoff durch die Düse 13 gedrückt wird.The nozzle 13 is connected to a storage container 15, which is airtight by a piston 16 to obin is completed. Above the piston 16, an overpressure is generated in the space 17, so that Adhesive is constantly pressed through the nozzle 13 via the pipe 18.

Die fertigen Bögen werden bei 20 gestapelt und SDäter längs der gestrichelten Linien 21 durchgeschnitten, so daß Bögen beispielsweise im Format DIN A 4 entstehen.The finished sheets are stacked at 20 and cut through along the dashed lines 21, so that sheets are produced, for example, in the DIN A4 format.

Eine «leiche Klebstoffauftrageeinrichtung ist unterhalb des Tisches 1 vorgesehen. Es sind hier eine aeriffelte Quetschwalze 34, eine mit flachen, jedoch breiten Erhebungen versehene Übertragungswalze 35 voroesehen, ferner eine die Ringscheiben tragende Wafze 38 sowie eine Umlenkwalze 12, welche die von Vorratsrollen 40 abgezogenen Papierstreifen 41 mit Hilfe einer weiteren Walze 42 von unten an die Bögen 2 drückt. . .A light glue applicator is below of the table 1 is provided. There are one here a corrugated squeegee roller 34, one with flat ones, however Broad elevations provided transfer roller 35, also one that supports the ring disks Wafer 38 and a guide roller 12, which the from the supply rolls 40 pulled paper strips 41 with the help of a further roller 42 from below to the Arch 2 presses. . .

Der Klebstoff wird dieser Einrichtung mit Hilfe einer Düse 60 zugeführt, welche mit dem Behälter 15 verbunden ist.The adhesive is fed to this device with the aid of a nozzle 60 which is connected to the container 15 connected is.

Der Klebstoff läuft beim Einfüllen in den oberen Keil zwischen der Quetschwalze 34 und der Übertragungswalze 35 durch die Lücken zwischen diesen Walzen nach unten durch und bildet jetzt unterhalb der Beriihrungslinie dieser Walzen einen Keil. Die Walzen drehen sich derart, daß sie den Klebstoff dieses Keiles wieder gegen die Beriihrungslinie der Walzen drücken, wodurch einerseits die Verteilung des Klebstoffes längs der Walzen bewirkt wird und andererseits der Klebstoffilm auf den Erhebungen der Übertragungswalze 35 gebildet wird. The adhesive runs during filling in the upper wedge between the nip roll 34 and the transfer roller 35 through the gaps between these rolls down by these rollers and is now below the Beriihrungslinie a wedge. The rollers rotate in such a way that they press the adhesive of this wedge again against the contact line of the rollers, whereby on the one hand the distribution of the adhesive along the rollers is effected and on the other hand the adhesive film is formed on the elevations of the transfer roller 35.

Die Wirkungsweise ist damit dieselbe wie bei der oberhalb des Tisches vorgesehenen Vorrichtung.The mode of operation is thus the same as that of the device provided above the table.
