Abstract

The brush material (3) is held in a liner (4) and cut by the knife (1) that is mounted in a holder (2). The knife is circular and rotates periodically. The rotating movement is achieved by mounting the knife in the holder eccentrically. The knife is rotated during the cutting process. The worn cutting edge is moved from the cutting zone and can be sharpened.

Description

Die Erfindung betrifft Scheren zum Schneiden von Bürsten­ material (Draht, Synthetikfasern, Naturborsten und andere mehr).The invention relates to scissors for cutting brushes material (wire, synthetic fibers, natural bristles and others more).

Es sind bekannte Scheren mit einer Schneidbuchse und Scher­ messer. Das Material wird durch die Buchse geschoben, fest­ geklemmt und mit dem Messer gegen die Kante der Buchse durchgeschnitten. Das Messer hat einen hohen Verschleiß im Kontaktbereich zum Material, während die anderen Teile der Messerkante nicht benutzt werden. Der Schnittvorgang erfolgt mit einem drückenden Messer, was teilweise zur Verquetschung des Materials führt. Zum Nachschleifen muß das Messer aus dem Messerhalter herausgenommen werden.There are known scissors with a cutting bush and shear knife. The material is pushed through the bush, firmly clamped and with the knife against the edge of the socket cut across. The knife has a high wear in the Contact area to the material while the other parts of the Knife edge can not be used. The cutting process takes place with a pressing knife, which is partly to squeeze of the material leads. For regrinding, the knife must be removed from the Knife holder can be removed.

Der Erfindung liegt die Aufgabe zugrunde, das Messer so aus­ zubilden, daß der Verschleiß gleichmäßig auf der Schneide­ kante des Messers verteilt wird, daß das Nachschleifen während des Betriebes der Schere erfolgt und der Schnitt mit einem drückenden und gleichzeitig ziehenden Messer durchge­ führt wird.The invention is based, so the knife form that wear evenly on the cutting edge edge of the knife is distributed that the regrinding during the operation of the scissors and the cut with a pushing and pulling knife leads.

Durch die Erfindung wird die Aufgabe insofern gelöst, daß das Messer kreisförmig ausgeführt und während des Schnittes weitergedreht wird, was einen ziehenden Schneideablauf er­ gibt. Die verschlissene Schneidekante des Messers wird aus dem Schnittbereich herausgeführt und nachgeschliffen. The object is achieved by the invention in that the Knife circular and during the cut is rotated, what a pulling cutting sequence he gives. The worn cutting edge of the knife is out led out of the cutting area and reground.  

Die Zeichnungen zeigen in Fig. 1 eine Vorderansicht der Schere, in Fig. 2 einen Schnitt A-B von Fig. 1.The drawings show in Fig. 1 is a front view of the scissors in Fig. 2 is a section AB of FIG. 1.

Die in den Fig. 1 und 2 dargestellte Schere beschneidet mit dem Messer (1) am Messerhalter (2) das Bürstenmaterial (3) in der Schneidebuchse (4).The scissors shown in Figs. 1 and 2 cuts with the knife (1) on the knife holder (2), the brush material (3) in the cutting receptacle (4).
