Description

Die Erfindung betrifft eine Vorrichtung zum Längsschneiden von Bahnen nach dem Oberbegriff von Anspruch 1.The invention relates to a device for longitudinally cutting webs according to the preamble of claim 1.

Aus der DE-OS 21 64 554 ist eine Vorrichtung bekannt, bei der zum Absaugen des Schnittstaubes über den Innenraum des Walzenkörpers dessen Walzenmantel mit Durchbrüchen ausgestattet ist. Die Herstellung und Wartung des Walzenkörpers, inclusive seines Anschlusses an einen Unterdruckerzeuger, ist aufwendig und teuer.From DE-OS 21 64 554 a device is known in which Extracting the cut dust over the interior of the roller body whose roll shell is equipped with openings. The production and maintenance of the roller body, including its connection to one Vacuum generator is complex and expensive.

Aus der DE-PS 4 44 041 ist eine Vorrichtung zum Längsschneiden von Bahnen mit einem in eine als Gegenschneide wirkende Schneidnut eines Walzenkörpers eingreifenden Kreismesser sowie einer im Bereich der Schnittstelle angeordneten, mit ihrer Öffnung entgegen der vom Walzenkör­ per geschnittenen ablaufenden Bahn gerichteten Saugdüse bekannt. Nach­ teilig ist bei dieser Vorrichtung, daß nur ein geringfügiger, von dem aus der Bahn wieder austretenden Messer mitgeführter Teil des Schnittstaubes abgesaugt wird, während der größte Teil des Schnittstaubes nicht absaug­ bar unterhalb der Bahn verbleibt und sich am Walzenkörper festsetzen kann.From DE-PS 4 44 041 is a device for slitting Paths with a in a cutting groove acting as a counter cutting edge Circular knife engaging roller body and one in the area of Interface arranged, with its opening opposite that of the roller body known by cut running web directed suction nozzle. After Part of this device is that only a slight one, from which the Part of the cutting dust that comes out of the web with the knife is suctioned off, while most of the cutting dust does not suction bar remains below the web and can attach to the roller body.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Längs­ schneiden von Bahnen gemäß dem Oberbegriff von Anspruch 1 zu schaf­ fen, die mit einfachen Mitteln eine wirksame Absaugung des Schnittstaubes unmittelbar am Entstehungsort garantiert. Die Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 erfüllt.The invention has for its object a device for longitudinal cutting sheets according to the preamble of claim 1 to sheep fen, the effective extraction of the cutting dust with simple means guaranteed right at the point of origin. The task is performed by the characteristic features of claim 1 fulfilled.

Die Erfindung ermöglicht eine wirksame Absaugung des Schnittstaubes vom Walzenkörper weg unmittelbar am Entstehungsort unterhalb der Bahn, wodurch ein Festsetzen des Schnittstaubes auf dem Walzenkörper und eine Verschmutzung der Vorrichtung insgesamt weitestgehend vermieden wird. The invention enables effective extraction of the cut dust from Roll body away directly at the point of origin below the web, which causes the cutting dust to settle on the roller body and a Overall, contamination of the device is largely avoided.  

Eine besonders wirkungsvolle Gestaltung und Anwendung der Saugdüse enthält der Unteranspruch.A particularly effective design and application of the suction nozzle contains the sub-claim.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher erläu­ tert. In der zugehörigen Zeichnung zeigen:The invention is explained in more detail below using an exemplary embodiment tert. In the accompanying drawing:

Fig. 1 einen Querschnitt einer Vorrichtung zum Längsschneiden von Bahnen gemäß Schnitt A-A von Fig. 2, Fig. 1 shows a cross section of a device for slitting of webs according to the section AA of Fig. 2,

Fig. 2 eine Längsansicht der Vorrichtung. Fig. 2 is a longitudinal view of the device.

Fig. 1 zeigt einen Walzenkörper 1 einer angetriebenen Zugwalze für eine oder mehrere beispielsweise aus Papier bestehende Bahnen 2. Der Walzen­ körper ist jeweils als Teil einer Längsschneidevorrichtung mit einer Schneid­ nut 3 ausgestattet, in die ein die Schneidvorrichtung komplettierendes, über je einen beidseitig angeordneten kreisförmigen Bund 4; 5 (Fig. 2) vom Walzenkörper über Friktion angetriebenes, abstellbares Kreismesser 6 ein­ greift. Fig. 1 shows a roller body 1 of a driven draw roller for one or more, for example, consisting of paper webs 2. The roller body is each equipped as part of a longitudinal cutting device with a cutting groove 3 into which a cutting device is completed, each with a circular collar 4 arranged on both sides; 5 ( Fig. 2) from the roller body via friction driven, adjustable circular knife 6 engages.

Unterhalb der vom Walzenkörper 1 ablaufenden, geschnittenen Bahn 2 ist eine Saugdüse 7 mit ihrer Öffnung 8 entgegen der Laufrichtung der Bahn 2 weisend im Bereich der Schnittstelle der Schneidnut 3 angeordnet.Below the cut web 2 running from the roll body 1 , a suction nozzle 7 is arranged with its opening 8 facing the direction of travel of the web 2 in the region of the interface of the cutting groove 3 .

Für eine besonders intensive Absaugung des Schnittstaubes kann gemäß strichpunktierter Darstellung die Saugdüse 7′ das Kreismesser 6 untergrei­ fend verlängert und mit einer seitlichen, der Schnittstelle zugewandten Öffnung 8′ ausgestattet werden.For a particularly intensive suction of the cut dust, the suction nozzle 7 ', the circular knife 6 can be extended underneath according to the dash-dotted line and equipped with a side opening 8 ' facing the interface.

Wie Fig. 2 zu entnehmen, sind die Saugdüsen 7 über Rohrleitungen 9 in nicht dargestellter Weise mit einem Staubfilter und Unterdruckerzeuger verbunden.As can be seen Fig. 2, the suction nozzles 7 are connected via pipes 9 in a manner not shown with a dust filter and vacuum generator.
