Description
DEUTSCHESGERMAN
Bei mancherlei· Arten, der Papierverarbeitung kann der Arbeitsprozeß dadurch gestört werden, daß dem Papier Staub anhaftet, der in Form von Fasern, Faserbruchstücken, Füllstoff-, Leim- und Streichmassepartikeln durch mechanische Beanspruchungen aus dem Papier herausgelöst worden ist. Bei dem Bedrucken als dem wirihstigsten Prozeß der P apier verarbeitung gelangen diese Staubpartikeln entweder direkt oder wie bei dem in dieser Hinsicht besonders empfindlichen Offsetdruckverfahren zuerst über ein Gummituch auf die Druckform. Die Staubpartikeln beeinflussen die Druckform nachteilig, sie reichern sich in der Druckfarbe an, führen zu Qualitätseinbußen des Druckerzeugnisses und wegen der häufigen Notwendigkeit desReinigens der entsprechenden Elemente der Druckmaschine zu einer Verminderung der Druckerzeugung. In some · ways that paper processing can the work process is disturbed by the fact that dust adheres to the paper, which in the form of fibers, fiber fragments, Filler, glue and coating paste particles due to mechanical stress has been removed from the paper. In printing as the most economical process of paper processing these dust particles arrive either directly or as in the case of the particularly sensitive in this regard Offset printing process first over a rubber blanket on the printing form. The dust particles affect the printing form disadvantageous, they accumulate in the printing ink, lead to a loss of quality Printed matter and because of the frequent need to clean the corresponding elements of the Press to reduce the pressure generated.
Den bisher bekanntgewordenen Vorrichtungen zur Beseitigung des= Papierstaubes ist allen gemeinsam, daß sie entweder durch Bürsten oder ähnliche Einrieb,-tungen auf das Papier einwirken, um den Staub abzuführen, und hierbei ungewollt Staub aufwirbeln — was besonders bei locker gearbeiteten Papieren sehr nachteilig sein kann —, oder daß sie den Staub, wo es sich um Absaugen handelt, nicht in ausreichendem Maße entfernen.The devices that have become known so far for removing the = paper dust are common to all, that they either by brushing or similar rubbing act on the paper to remove the dust, and thereby unintentionally stir up dust - which can be very disadvantageous, especially with loosely worked papers - or that they remove the dust, where it is a question of suction, do not remove sufficiently.
Versuchswahrnehmungen haben nunmehr gezeigt, daß man ohne eine ins Gewicht fallende mechanische Beanspruchung des Papiers eine auffallend günstige, also sehr weitreichende Staubabnahme erzielen kann, wenn auf dem Papier eine mit einem Gummiüberzug versehene Wal ze sich abwälzt und deren Oberfläche hierbei durch Adhäsionskräfte die Staubpartikeln abhebt.Experimental perceptions have now shown that without a significant mechanical Stress on the paper can achieve a noticeably favorable, i.e. very extensive, dust removal, when a rubber-coated roller rolls on the paper and its surface here the dust particles are lifted by adhesive forces.
Die Vorrichtung gemäß der Erfindung besteht demzufolge darin, zum fortlaufenden Entfernen des Staubes von Papierbahnen oder -bogen angetriebene Walzen oder endlose Bahnen vorzusehen, die mit Gummi oder gummiähnlichem Material überzogen sind oder aus diesem bestehen, welche bei einer der Laufgeschwindigkeit des Papiers entsprechenden Umlaufgeschwindigkeit an dieses angedrückt werden und dabei durch Adhäsion den Staub abheben.The device according to the invention therefore consists in the continuous removal of the To provide dust of paper webs or sheets driven rollers or endless paths that with Rubber or rubber-like material are coated or consist of this, which at one of the running speed of the paper to be pressed against the corresponding rotational speed and thereby take off the dust by adhesion.
Eine erfindungsgemäße Vorrichtung zum Entfernen des Staubes ist an Hand der Zeichnung in zwei- Ausführungsbeispielen erläutert.A device according to the invention for removing the dust is shown in two exemplary embodiments with reference to the drawing explained.
Fig. 1 zeigt mehrere Paare von angetriebenen Gummiwalzen Ij die hintereinander angeordnet sind, zwischen denen das Papier 2, um beide Seiten zu entstauben, hindurchgeführt wird. InFig. 1 shows several pairs of driven rubber rollers Ij which are arranged one behind the other, between which the paper 2, in order to remove dust from both sides, is passed. In
Fig. 2 ist eine ähnliche Vorrichtung dargestellt, bei der endlose Gummibahnen 3 verwendet werden, die durch Führungswalzen 4 angetrieben sind. Man kann die Vorrichtung auch so abwandeln, daß nur eine Seite des Papiers von dem Papierstaub befreit wird.Fig. 2 shows a similar device in which endless rubber sheets 3 are used, the are driven by guide rollers 4. The device can also be modified so that only one side the paper is freed from the paper dust.

Der durch den Gummi oder das gummiähnliche Material vom Papier abgehobene Staub kann von Zeit zu Zeit oder auch laufend von diesem entfernt werden, indem man mit Filz, Samt oder ähnlichem Material überzogene Abstreifleisten oder Abstreifwalzen 5 verwendet und diese während des Betriebs leicht anfeuchtet. Die Abstreifwalzen werden nach gewissen, dem Staubanfall angepaßten einstellbaren Zeiten entweder von Hand oder automatisch um einen kleinen Winkel gedreht, so daß eine neue Abstreiflinie die alte ablöst. Nach bestimmten Zeiten, z. B. nach einem Arbeitstag, werden die Staubabstreifwalzen oder -leisten gereinigt. Hinter der Abstreifvorrichtung kann durch eine Schlitzdüse 6 Luft geblasen werden, um die aufgebrachte Feuchtigkeit zu verdunsten.The dust lifted off the paper by the rubber or rubber-like material may over time to be removed from this periodically or continuously by covering with felt, velvet or similar material coated wiper strips or wiper rollers 5 used and this slightly moistened during operation. After certain adjustable times, which are adapted to the amount of dust, the stripping rollers are either manually or automatically rotated by a small angle so that a new scraper line replaces the old one replaces. After certain times, e.g. B. after a working day, the dust scraper or -bars cleaned. Behind the stripping device, air can be blown through a slot nozzle 6, to evaporate the applied moisture.
