Abstract

A main roller (1) has a circumferential groove and an OD around which thin sheet material (2) moves. A second roller (4) has one or more cutting wheels (6) which rotate in contact with the sidewalls of the grooves. A manifold (9) is fitted with a number of inlet nozzles (7) whose dia. decreases with distance from the manifold. The reduced dia. end of each suction nozzle is fitted with a contoured tip (7') and fits into one of the grooves. As the material is cut by the blade any dust or swarf is extracted by a suction applied in the manifold.

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 derartige 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.Such a device is known from DE-OS 21 64 554, in which for 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.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Längs­ schneiden von Bahnen gemäß dem Oberbegriff von Anspruch 1 zu schaf­ fen, die einfach kostengünstig herzustellen ist und eine wirksame Absau­ gung 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, which is easy to manufacture inexpensively and effective suction cut dust guaranteed at the point of origin. The Object is achieved by the characterizing features of claim 1.

Durch den Einsatz der Saugdüse werden nur kleine Luftmengen und damit ein Unterdruckerzeuger geringer Leistung benötigt. Daraus ergibt sich auch eine geringe Geräuschentwicklung.By using the suction nozzle, only small amounts of air and therefore a low power vacuum generator is required. It also follows from this a low noise level.

Außerdem verhindert die Vorrichtung weitestgehend einen das Festsetzen begünstigenden Kontakt des Schnittstaubes mit dem Walzenkörper und ist ihre Anordnung unter der Warenbahn gegenüber nach außen gekapselten Absaugungen platzsparend.In addition, the device largely prevents jamming favoring contact of the cut dust with the roller body and is their arrangement under the web opposite to encapsulated outside Extractors save space.

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 zeigenThe invention is explained in more detail below using an exemplary embodiment tert. Show 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.
