Description
Vorrichtung zum Ankleben einer ablaufenden Papierbahn an die Papierbahn einer neuen Rolle für Rotationsdruckmaschinen Bei Rotationsdruckmaschinen wird der Anfang einer neuen Papierrolle mit dem ablaufenden Strang meist durch Kleben verbunden. Dabei stellt sich der Nachteil heraus, daß das äußerste Ende des neuen Stranges häufig herabhängt und während des Weiterganges durch die Maschine zurückgeschlagen wird, so daß der Klebstoff auf die Leitwalzen und Zylinder gelangt und allerlei Unannehmlichkeiten verursacht.Device for gluing a running paper web to the paper web a new roll for rotary printing machines. In rotary printing machines, the The beginning of a new roll of paper is usually connected to the running strand by gluing. This has the disadvantage that the extreme end of the new strand often drooping and knocked back while moving through the machine so that the glue gets onto the guide rollers and cylinders and all sorts of things Inconvenience caused.
Zum Zusammenpressen der beiden Papierstränge an der Klebestelle ist eine Bürstenwalze verwendet worden, deren Umfangsgeschwindigkeit der Papierbahngeschwindigkeit entsprach. Durch eine solche Bürste findet aber bei schnell laufenden Papiersträngen ein ungenügendes Glätten der Klebestelle statt, auch wird der Klebstoff nicht gegen das Strangende verteilt, so daß ein Zurückschlagen dieses Endes und ein Verschmieren des Klebstoffes auf die Maschinenteile immer noch zu befürchten ist.To press the two strands of paper together at the glue point a brush roller has been used, the peripheral speed of the paper web speed corresponded. With such a brush, however, strands of paper can be found in the case of fast-moving strands of paper an insufficient smoothing of the glued place takes place, also the glue does not counteract the end of the strand spread so that kickback of this end and smearing of the adhesive on the machine parts is still to be feared.
Gemäß der Erfindung soll nun der in dem Buchbinder- und Tapezierergewerbe übliche, mit der Hand ausgeführte Anklebevorgang in der Weise möglichst nachgeahmt werden, daß die Verbindungsstelle der Stränge durch eine Bürstenwalze geglättet wird, deren Umfangsgeschwindigkeit größer ist als die Geschwindigkeit der Papierbahn.According to the invention is now to be used in the bookbinding and upholstery trade The usual hand-held gluing process is imitated as much as possible be that the junction of the strands smoothed by a roller brush whose peripheral speed is greater than the speed of the paper web.
Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise veranschaulicht, und zwar zeigen: Abb. 1 eine Seitenansicht des Papierrollenträgers mit der Vorrichtung zum Verbinden der Papierstränge und Abb. z eine Seitenansicht der Ausstreichvorrichtung für die Klebestelle in einem größeren Maßstab.The drawing shows an embodiment of the subject matter of the invention for example illustrated, namely: Figure 1 is a side view of the paper roll support with the device for connecting the paper strands and Fig. z a side view the spreading device for the splice on a larger scale.
Die Papierrollen a sind in einem Träger b gelagert, der sich um einen Zapfen c dreht, so daß eine Ralle nach der anderen gegen den Antriebsgurt d angepreßt werden kann. Der Gurt d wird zwangsläufig angetrieben. Der ablaufende Strang e wird über die Leitwalzen f, g, lt in die Druckwerke geführt. Während des Ablaufens des Stranges e wird das Ende der neuen Papierrolle mit Klebstoff bestrichen und der Träger b alsdann so weit gedreht, daß die neue Rolle in die Stellung gemäß Abb. r kommt, in der das mit Klebstoff versehene-Strangende gegen den ablaufenden Strange gepreßt wird. Von der Walze f (Abb. r) ist eine an sich bekannte Bürstenwalze i in Schwingarmen k gelagert, die in der ausgezogenen Stellung oder in der punktierten Stellung durch einen in Löcher des Gestelles eingreifenden Zapfen l festgehalten werden kann. In der ersten Stellung berührt die Walze i den über die Leitwalzen f laufenden Strang, während sie in der abgeschwenkten Stellung leer läuft. Mittels Zahnräder na, n, o, p, q, r, s und t wird die umlaufende Bürstenwalze i erfindungsgemäß mit solcher Geschwindigkeit angetrieben, daß deren Umfang in der Laufrichtung des Stranges dieseln gegenüber voreilt.The paper rolls a are mounted in a carrier b which rotates about a pin c so that one ratchet after the other can be pressed against the drive belt d. The belt d is inevitably driven. The unwinding strand e is fed into the printing units via the guide rollers f, g, lt. While the strand e is running, the end of the new paper roll is coated with glue and the carrier b is then turned so far that the new roll comes into the position shown in Fig. R, in which the strand end provided with adhesive is pressed against the running strand will. From the roller f (Fig. R) a known brush roller i is mounted in swing arms k, which can be held in the extended position or in the dotted position by a pin l engaging in holes in the frame. In the first position the roller i touches the strand running over the guide rollers f , while in the pivoted position it runs idle. By means of gears na, n, o, p, q, r, s and t , the rotating brush roller i is driven according to the invention at such a speed that its circumference leads the dies in the running direction of the strand.
Die Verbindungsstelle der beiden Stränge geht also über die Leitwalze f und wird dabei von der Bürstenwalze i, die mit größerer Geschwindigkeit angetrieben wird als die ablaufenden Papierstränge, durch Reibung in der Laufrichtung ausgestrichen. Alsdann wird der alte Strang e unterhalb der neuen Rolle abgerissen und die verbrauchte Rolle entfernt.The connection point between the two strands goes over the guide roller f and is driven by the roller brush i, which is at a higher speed is, as the unwinding paper strands, spread out by friction in the running direction. Then the old strand e underneath the new roll is torn off and the used one Role removed.
