Description
Vorrichtung zum Schneiden von Fäden aus Metallbahnen Beim Schneiden schmaler Streifen aus Bahnen, die z.B. als Fäden zum Weben dienen sollen, verfährt man bisher so, daß die Schneidwerkzeuge in einem der Breite der zu erzeugenden Streifen entsprechenden Abstand nebeneinander angeordnet und so mit dem zu zerschneidenden Gut in Eingriff gebracht werden.Device for cutting threads from metal webs when cutting narrow strips of webs that are to be used as threads for weaving, for example so far so that the cutting tools in one of the width of the strips to be produced corresponding distance next to each other and so with the to be cut Well engaged.
Versucht man aber, sehr schmale Streifen zu schneiden, so reißen die Streifen während des Arbeitens sehr bald ab. -Da nämlich die Schneidwerkzeuge eine gewisse Eigendicke haben, kann nach dem bekannten Verfahren 'nur so lange gearbeitet werden, wie der Werkstoff sich dank seiner Elastizität seitlich zusammendrücken läßt, ohne daß bei der gleichzeitig starken Zugbeanspruchung seine Festigkeitsgrenzen überschritten werden. Werden die Messer zu dicht nebeneinander angeordnet, so kann der Werkstoff, der von beiden Seiten zusammengedrängt wird, nicht mehr ausweichen, so daß die Streifen abreißen.But if you try to cut very narrow strips, they will tear Strip off very soon while working. -Because namely the cutting tools one have a certain intrinsic thickness, the known method can only work for so long how the material compresses laterally thanks to its elasticity leaves, without its strength limits at the same time strong tensile stress be crossed, be exceeded, be passed. If the knives are arranged too close to one another, then the material that is being pressed together by both sides can no longer evade, so that the strips tear off.
Zum Schneiden breiter Streifen aus nachffi U ebigem Stoff sind zwar Schneidvorrichtun - gen bekannt, bei denen zwischen umlaufenden Messern die einzelnen Streifen an den Schneidstellen ausweichen können, doch eignen sich solche Vorrichtungen zum Herstellen äußerst schmaler Streifen ebenfalls nicht, da auch hier das Abreißen der Streifen eintritt. Vorliegende Erfindung betrifft eine Vorrichtung, die das Schneiden der schmalsten Metallstreifen dadurch ermöglicht, daß die feststehenden Messer der Schneidvorrichtung gestaffelt angeordnet sind, so daß beim Schneiden sehr schmaler Streifen der abgetrennte Faden seitlich ausweichen kann.Although are for cutting wide strip of nachffi U ebigem material Schneidvorrichtun - gen known which can avoid the cutting points between rotating blades, the individual strips, but such devices are also not suited for producing extremely narrow strip, since here the tearing of the strip entry. The present invention relates to a device which enables the cutting of the narrowest metal strips in that the fixed knives of the cutting device are arranged in a staggered manner, so that when cutting very narrow strips, the severed thread can escape laterally.
Auf der Zeichnung ist beispielsweise eine Vorrichtung zur Ausführung des Verfahrens dargestellt.In the drawing, for example, is a device for execution of the procedure.
Abb. r zeigt die Vorrichtung in Seitenansicht, Abb, a in Draufsicht.Fig. R shows the device in side view, Fig, a in plan view.
Das zu schneidende Gut, z. B. eine Bahn a, wird von einer Trommel b im Sinne des Pfeiles c abgewickelt. Auf dem Arbeitstisch d sind die feststehenden Messer e gestaffelt angeordnet. Die Streifen f werden zwischen Rollen g hindurchgeführt und auf Spulen h aufgewickelt. Zweckmäßig wird über den Messern ein elastisches Widerlager, z. B. eine Filzplatte, angeordnet, um die Fäden zu führen.The goods to be cut, e.g. B. a web a, is driven by a drum b handled in the direction of arrow c. The stationary ones are on the work table d Knife e arranged in a staggered manner. The strips f are passed between rollers g and wound on spools h. It is useful to have an elastic over the knives Abutment, e.g. B. a felt plate, arranged to guide the threads.
