Description

Beim Ausschneiden von Drahtgaze mittels einer Schere oder einer anderen mechanischen Schneidvorrichtung tritt derÜbelstand auf, daß dieSchnittkante durch Ausfransen der durchschnittenen Drähte rauh und unansehnlich wird.When cutting out wire gauze with scissors or another mechanical cutting device, the debris occurs that the cutting edge passes through Fraying of the cut wires becomes rough and unsightly.

Die Erfindung bezweckt, diesen Übelstand zu vermeiden, was erfindungsgemäß dadurch erreicht wird, daß die Drahtgaze durch elektrische Widerstandserhitzung zerschnitten und gleichzeitig die Schnittkanten verschweißt werden.The aim of the invention is to avoid this drawback, something according to the invention is achieved in that the wire gauze by electrical resistance heating cut and at the same time the cut edges are welded.

Die Vorrichtung zur Ausführung dieses Verfahrens besteht erfindungsgemäß aus einem mit der einen Klemme der Sekundärwicklung eines Transformators verbundenen Schneidmesser aus Wolfram und einem mit der anderen Klemme der Sekundärwicklung des Transformators verbundenen, als Auflage für die Gaze dienenden Tisch aus leitendem Material.The device for carrying out this method is according to the invention from one connected to one terminal of the secondary winding of a transformer Cutting knife made of tungsten and one with the other terminal of the secondary winding connected to the transformer, serving as a support for the gauze table made of conductive Material.

In der Zeichnung ist die Vorrichtung zur Ausübung des erfindungsgemäßen Verfahrens dargestellt. Mit i ist ein flaches, mit Schneide versehenes Wolframstück bezeichnet, das in dem Handgriff 2 befestigt ist und mit der einen Klemme der Sekundärwicklung 3 eines Transformators verbunden ist, dessen Primärwicklung q. mit wahlweise ein- oder ausschaltbaren Anzapfungen versehen ist. Mit der anderen Klemme der Sekundärwicklung ist eine metallische Tischplatte 5 verbunden, auf die die zuschneidende Drahtgaze 6 aufgelegt wird.In the drawing, the device for exercising the inventive Procedure shown. With i is a flat, cutting edge piece of tungsten referred to, which is fixed in the handle 2 and with one terminal of the secondary winding 3 of a transformer is connected, the primary winding of which q. with optional or taps that can be switched off. With the other terminal of the secondary winding a metal table top 5 is connected to which the wire gauze to be cut 6 is launched.

Die Führung des Schrneidmessers i kann von Hand oder mittels einer geeigneten Vorrichtung erfolgen. Die zu erzielende Schnittgeschwindigkeit hängt von dem Schnittdruck und der eingestellten Transformatorstufe ab. Durch den über das Wolframmesser und die Drahtgaze fließenden Strom wird bei Aufheizung des Wolframmessers die Gaze getrennt, wobei die Schneidkanten der zwischengelegten Drahtgaze verschweißt werden. Ein Ausfransen der einzelnen Drähte ist dadurch nicht mehr möglich. Die Schnittkanten behalten ein glattes, sauberes Aussehen.The guidance of the cutting knife i can be done by hand or by means of a suitable device. The cutting speed to be achieved depends on the cutting pressure and the set transformer stage. Through the over The tungsten knife and the wire gauze flowing current will be when the tungsten knife is heated the gauze separated, the cutting edges of the interposed wire gauze being welded together will. Fraying of the individual wires is no longer possible. the Cut edges keep a smooth, clean appearance.
