Description

Translated fromGerman

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

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

Um diesen Nachteil zu beheben, wird bei einem Falztrichter mit längs der Trichterkanten angeordnetenBlasluftöffnungen der Erfindung gemäß jede Trichterkante und die Trichternase mit je einer eigenenLuftleitung 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 innenliegendeBahn gleitet.In order to remedy this disadvantage, a former is arranged along the edges of the formerBlow air openings of the invention according to each funnel edge and the funnel nose each with its ownAir 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 thatthat along the whole funnel a coherent air cushion is created, over which the inner oneRailway slides.

In der Zeichnung ist ein Ausführungsbeispiel schematisch dargestellt. Es zeigtFig. 1 eine Vorderansicht eines Falztrichters.An exemplary embodiment is shown schematically in the drawing. It showsFig. 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. DieZuleitung zu den Bohrungen 2 und 3 erfolgt in der Nähe der Trichterspitze, wie bei 6 und 7 angedeutetist. In den Leitungen sind Absperrorgane 8 und 9 vorgesehen, mit welchen die Blasluftzufuhr reguliertwerden kann. Für den Bereich an der Trichternase selbst ist eine weitere Zuleitung 10 mit einem Absperrorgan11 angeordnet, welche in zwei kurze Bohrungen 12 und 13 mündet, die gegen die aufliegendePapierbahn 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. theThe feed line to the bores 2 and 3 takes place in the vicinity of the funnel tip, as indicated at 6 and 7is. Shut-off devices 8 and 9 are provided in the lines, with which the blown air supply is regulatedcan be. For the area on the funnel nose itself there is another feed line 10 with a shut-off device11 arranged, which opens into two short bores 12 and 13 that lie against the overlyingPaper web with a number of smaller blow holes Fold funnel for longitudinal folding

Durch eine derartige Zuführungan der besonders kritischen Stelle, d. h. an der Trichternase, kann die erforderliche Blasluftzufuhr einreguliertwerden, die ein entsprechend starkes Luftpolster bewirkt.14, 15 are provided. By such a feedat the particularly critical point, d. H. at the funnel nose, the required air supply can be regulatedwhich causes a correspondingly strong air cushion.

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