Description

Verfahren und Fadenführer zur Verminderung der Reibung eines Fadens, insbesondere eines"Künstseidefadens Die Erfindung betrifft ein Verfahren zur Verminderung -der Reibung eines Fadens, insbesöndere eines- Kunstseidefadens, beim -Gleiten über einen Fadenführer. Die Erfindung besteht darin, daß dem Fadenführer .Schwingungen von etwa der Größenordnung z04 I3z erteilt werden. .Process and thread guide to reduce the friction of a thread, in particular an "artificial silk thread. The invention relates to a method for reducing -the friction of a thread, in particular a- rayon thread, when sliding over a thread guide. The invention consists in that the thread guide .Schwimmern of about the order of magnitude z04 I3z. .

Es ist bekannt, Fadenführern eine Zitterbewegung zu erteilen. Diese Zitterbewegung soll dazu dienen, -den aufzuwickelnden Faden wellenförmig- zü verlegen. Das Problem der Verminderung der Fadenreibung beim Gleiten über einen Fadenführer ist- dabei. jedoch weder gestellt noch gelöst worden.It is known to give thread guides a trembling movement. These The trembling movement should serve to lay the thread to be wound up in a wave-like manner. The problem of reducing the thread friction when sliding over a thread guide is in. however, it has neither been asked nor resolved.

Erfindungsgemäß kann der Fadenführer in jeder möglichen bekannten Weise in hochfrequente Schwingungen versetzt werden. Besonders zweckmäßig indessen ist dabei die Anwendung von Magnetostriktion.According to the invention, the thread guide can be known in any possible way Way are set in high-frequency vibrations. Particularly useful, however is the application of magnetostriction.

Man kann nun entweder den Fadeaiführerlialter oder aber den Fadenführer selbst aus magnetostriktivem Baustoff herstellen. Der aus magnetostriktivem Baustoff bestehende Fadenführerhalter. bzw: Fadenführer wird dann zwecks Erzeugung eines magnetischen Wechselfeldes finit einer Drahtspule umgeben, so daß der Fädenführerhalter oder der Fadenführer selbst bei Erzeugung des magnetischen Wechselfeldes, insbesondere durch einen Niederfrequenzgenerator, in einen mechanischen Schwingungszustand versetzt wird.You can either use the Fadeaiführerlialter or the Fadenführer Manufacture yourself from magnetostrictive building material. The one made of magnetostrictive building material existing thread guide holder. or: thread guide is then for the purpose of generating a alternating magnetic field finitely surrounded by a wire coil, so that the thread guide holder or the thread guide itself when generating the alternating magnetic field, in particular by a low frequency generator, placed in a mechanical vibration state will.

An Hand der Zeichnung wird die Erfindung näher erläutert.The invention is explained in more detail with reference to the drawing.

Der Faden z wird mit einer bestimmten Geschwindigkeit über :einen Fadenführer 2 gezogen. Dabei ergibt sich im Faden vor denn Fadenführer eine Spanntuig P1 und hinter dem Fadenführer eine Spannung P2. Infolge des Reibungswiderstandes ist die SpannungP2 bekanntlich wesentlich größer als die Spannung Pi.The thread z is at a certain speed over: a Thread guide 2 pulled. This results in a tension in the thread in front of the thread guide P1 and behind the thread guide a tension P2. As a result of the frictional resistance the voltage P2 is known to be significantly greater than the voltage Pi.

Der Fadenführer ist an einem Halter 3 aus magnetostriktivem Baustoff, z. B. Nickel, befestigt. Dieser Halter ist von einer Spule 4 umgeben und wird von einem Niederfrequenzbcncrator aus mit Strom gespeist. Dadurch wird ein magnetisches Wechselfeld gebildet, unter dessen Einfluß der Halter 3 in longitudinale Schwingungen versetzt wird. Diese Schwingungen setzen die Reibung, die der Faden durch den Fadenführer erleidet, ganz betfächtlich herab, was sich darin zeigt, daß die Differenz aus P2-Pl erheblich geringer ist als bei nichtschwingenden Fadenführern.The thread guide is on a holder 3 made of magnetostrictive building material, z. B. nickel attached. This holder is surrounded by a coil 4 and is of a low frequency counter fed with electricity. Through this will formed an alternating magnetic field, under the influence of which the holder 3 in longitudinal Vibrations are added. These vibrations set the friction that the thread creates by the thread guide suffers, quite considerably, what is shown in the fact that the difference from P2-PI is considerably smaller than in the case of non-oscillating thread guides.

Beim Ausführungsbeispiel besteht nur der Halter 3 aus magnetostriktivem Werkstoff, der Fadenführer 2 dagegen nicht. Er kann aus Glas, Porzellan o. dgl. gefertigt.sein. Selbstverständlich kann auch der Fadenführer 2 selber aus magnetostriktivem Baustoff. bestehen; dann muß dieser jedoch eine solche Länge haben, daß um ihn eine Spule 4. herumgelegt werden kann.In the embodiment, only the holder 3 consists of magnetostrictive Material, the thread guide 2 on the other hand not. It can be made of glass, porcelain or the like. manufactured. Of course, the thread guide 2 itself can be made of magnetostrictive Building material. exist; but then this must have such a length that around it a Coil 4. can be laid around.

Bei hin und her gehenden FadenführerA kann die Stromzuleitung beispielsweise durch biegsame Drahtschnüre bewirkt werden.In the case of yarn guides A moving back and forth, the power supply line can, for example be effected by flexible wire cords.
