Description

Die Erfindung betrifft einen Falztrichter zum Längsfalzen von in Rotationsdruckmaschinen verarbeiteten Papierbahnen mit längs der Trichterk an ten angeordneten Blasluftöffnungen.The invention relates to a former for longitudinally folding processed in rotary printing machines Paper webs with air blast openings arranged along the funnel edges.

An den bisher bekannten Falztrichtern treten bei der Verarbeitung von mehreren übereinanderliegenden Papierbahnen auf der innersten Bahn infolge der Reibung Faltenbildungen und Farbschmieren auf. Man hat schon versucht, dies zu verhindern, indem man unmittelbar nach der Trichterwalze längs der Trichterkanten Luft eingeblasen hat. Damit sollte ein Luftpolster erzeugt und die Reibungen längs der Trichterkanten vermindert werden. Da das Luftpolster jedoch durch die im gleichen Sinn bewegte laufende Papierbahn gedrückt und verdrängt wird, kann dasselbe auch nicht immer bis zur Trichterspitze vordringen.The previously known formers occur when processing several superimposed Paper webs on the innermost web are wrinkled and smeared as a result of friction on. Attempts have already been made to prevent this by working lengthways immediately after the funnel roller the funnel edge has blown air. This should create an air cushion and reduce friction be reduced along the funnel edges. Since the air cushion, however, by the in the same sense moving moving paper web is pressed and displaced, the same can not always be up to the funnel tip advance.

Um diesen Nachteil zu beheben, wird bei einem Falztrichter mit längs der Trichterkanten angeordneten Blasluftöffnungen der Erfindung gemäß jede Trichterkante und die Trichternase mit je einer eigenen Luftleitung verbunden. Der Anschluß erfolgt dabei so, daß die Luft der laufenden Bahn entgegenströmt. Da jede Luftleitung mit einem eigenen Absperrorgan versehen ist, läßt sich der Luftdruck leicht so regulieren, daß längs des ganzen Trichters ein zusammenhängendes Luftpolster entsteht, über welches die innenliegende Bahn gleitet.In order to remedy this disadvantage, a former is arranged along the edges of the former Blow air openings of the invention according to each funnel edge and the funnel nose each with its own Air line connected. The connection is made in such a way that the air flows in the opposite direction to the running web. Since each air line is provided with its own shut-off device, the air pressure can easily be regulated in such a way that that along the whole funnel a coherent air cushion is created, over which the inner one Railway slides.

In der Zeichnung ist ein Ausführungsbeispiel schematisch dargestellt. Es zeigt Fig. 1 eine Vorderansicht eines Falztrichters.An exemplary embodiment is shown schematically in the drawing. It shows Fig. 1 is a front view of a former.

Fig. 2 eine Seitenansicht.Fig. 2 is a side view.

Am Trichterblech 1 sind in bekannter Weise längs der Trichterkanten Innenbohrungen 2, 3 angebracht, die gegen die aufliegende Papierbahn hin mit einer Anzahl kleinerer Blaslöcher 4, 5 versehen sind. Die Zuleitung zu den Bohrungen 2 und 3 erfolgt in der Nähe der Trichterspitze, wie bei 6 und 7 angedeutet ist. In den Leitungen sind Absperrorgane 8 und 9 vorgesehen, mit welchen die Blasluftzufuhr reguliert werden kann. Für den Bereich an der Trichternase selbst ist eine weitere Zuleitung 10 mit einem Absperrorgan 11 angeordnet, welche in zwei kurze Bohrungen 12 und 13 mündet, die gegen die aufliegende Papierbahn hin mit einer Anzahl kleinerer Blaslöcher Falztrichter zum LängsfalzenOn the funnel plate 1, inner bores 2, 3 are attached in a known manner along the funnel edges, which are provided with a number of smaller blow holes 4, 5 against the paper web resting on it. the The feed line to the bores 2 and 3 takes place in the vicinity of the funnel tip, as indicated at 6 and 7 is. Shut-off devices 8 and 9 are provided in the lines, with which the blown air supply is regulated can be. For the area on the funnel nose itself there is another feed line 10 with a shut-off device 11 arranged, which opens into two short bores 12 and 13 that lie against the overlying Paper web with a number of smaller blow holes Fold funnel for longitudinal folding

14, 15 versehen sind. Durch eine derartige Zuführung an der besonders kritischen Stelle, d. h. an der Trichternase, kann die erforderliche Blasluftzufuhr einreguliert werden, die ein entsprechend starkes Luftpolster bewirkt.14, 15 are provided. By such a feed at the particularly critical point, d. H. at the funnel nose, the required air supply can be regulated which causes a correspondingly strong air cushion.

Die Erfindung kann mit Erfolg auch bei bereits vorhandenen Falztrichtern verwendet werden, wenn die Zuführungen in der erfindungsgemäßen Weise angebracht und die längs in den Trichterkanten verlaufenden Bohrungen entsprechend abgeteilt werden, so daß die Trichternase eine eigene Blasluftzuführung und -regulierung erhält.The invention can also be used successfully with already existing formers, if the feeds attached in the manner according to the invention and those running longitudinally in the funnel edges Bores are divided accordingly, so that the funnel nose has its own blown air supply and regulation.
