Description

Der Erfindung liegt die Aufgabe zugrunde, die -dem Sauschwanzfadenführer 5 zu der Voreilrolle 8, Bauhöhe für die Arbeitseinheit zu vermindern, ohne die über eine Welle 9 durch ein Reibrad 10 angedaß die Bedienung der Zwirnstelle dadurch behindert trieben wird, das auf der Reibwalze 6 läuft,
wird. Die Bauhöhe einer Doppeldrahtzwirnmaschine Um den Abstand V zu überbrücken, ist ein Fadenwird weitgehend von dem Abstand bestimmt, der 65 umlenkrad 11 vorgesehen, dessen Durchmesser zwischen der Oberkante des die Ablaufspule um- praktisch dem Abstand V entspricht. Dieses Fadenhüllenden Spulentopfes und dem Sauschwanzfaden- umlenkrad 11 ist im gewählten Beispiel auf einem führer bestehen muß. Gestell, bestehend aus vier Beinen 12, gelagert, dieThe object of the invention is to reduce the height of the work unit from the pig tail thread guide 5 to the lead roller 8, without the fact that the operation of the twisting point is hindered by a friction wheel 10 via a shaft 9, which runs on the friction roller 6 ,
will. To bridge the height of a double-twisting machine by the distance V, a thread is largely determined by the distance, provided the return wheel 65 11, whose diameter between the top of the pay-out reel environmentally virtually corresponds to the distance V. This thread-enveloping bobbin pot and the pig tail thread deflecting wheel 11 must insist on a guide in the example chosen. Frame, consisting of four legs 12, supported the

bei 13 gelenkig miteinander verbunden sind. Zwischen den vorderen und hinteren Beinen 12 sind Brücken 14 vorgesehen, die eine Parallelbewegbarkeit des Fadenumlenkrades 11 sicherstellen. Infolge dieser Anordnung ist das Rad 11 in Richtung des Pfeiles 15, d. h. parallel zum Fadenlauf, zur Auflaufspule frei vor- und zurückbewegbar.at 13 are articulated together. There are bridges between the front and rear legs 12 14 are provided, which ensure that the thread deflecting wheel 11 can move in parallel. As a result of this Arrangement is the wheel 11 in the direction of arrow 15, i. H. parallel to the thread run, free to the take-up bobbin can be moved back and forth.

Damit das Rad 11, welches durch seine Bewegung in Richtung des Pfeiles 15 Spannungsspitzen im Faden ausgleichen kann, dem gewünschten Fadenzug angepaßt werden kann, ist an der Lagerung ein Gewicht 16 vorgesehen, das auf einer Spindel 17 verstellbar ist und dem Fadenzug entgegenwirkt.So that the wheel 11, which can compensate for tension peaks in the thread by its movement in the direction of arrow 15, can be adapted to the desired thread tension, a weight 16 is provided on the mounting, which is adjustable on a spindle 17 and counteracts the thread tension.

wird mittels einer Feder 18 an das Reibrad 6 angedrückt. An der Rolle 8 ist in an sich bekannter Weise ein konischer Abschnitt 19 vorgesehen, in den eine Schraubennut 20 eingearbeitet ist. Am Ende des konischen Teiles befindet sich ein Knopf 21.is pressed against the friction wheel 6 by means of a spring 18. On the roller 8, a conical section 19 is provided in a manner known per se, into which a screw groove 20 is incorporated. At the end of the conical part there is a button 21.

Der von der Doppeldrahtzwirnspindel 1 kommende Faden wird durch den Sauschwanzfadenführer 5 samt Umlenkröllchen 22 gezogen und alsdann zum Knopf 21 der Voreilrolle 8 geführt.The thread coming from the two-for-one twisting spindle 1 is velvet through the pig tail thread guide 5 Pulley 22 pulled and then led to button 21 of the lead roller 8.

Der Faden kann dann ohne weiteres auf das Umlenkrad 11 aufgelegt und in den Changierfadenführer 23 eingelegt werden, um auf der Spule 7 aufgespult zu werden, wobei der Faden über die Nut 20 selbsttätig in die Nut der Voreilrolle 8 einläuft.The thread can then easily be placed on the deflection wheel 11 and into the traversing thread guide 23 are inserted in order to be wound onto the bobbin 7, the thread passing over the groove 20 runs automatically into the groove of the lead roller 8.
