Bei den auf Spulmaschinen gewickelten Spulen wird das Ende des Fadens unter anderem an der Zulaufseite durch Ankleben oder auch durch Zusammenzwirnen mit dem Fadenanfang der Spule befestigt. Beide Arbeitsweisen haben Nachteile, indem bei ersterer durch den Klebstoff die Spule verdorben werden .kann, während bei der letzteren das zum Einfädeln und zum Probieren der Fadenspannung notwendige Abziehen des Fadenanfangs erschwert wird. Gemäß der vorliegenden Erfindung wird nun das Fadenende durch Andrehen befestigt, indem eine einfache oder mehrfache Fädenschlinge in den letzten Fadengängen gebildet wird, die in sich zusammengezwirbelt wird.In the case of the bobbins wound on winding machines, the end of the thread is, among other things on the inlet side by gluing or by twisting together with the beginning of the thread attached to the coil. Both ways of working have disadvantages, in that the former is caused by the adhesive the bobbin can be spoiled, while with the latter the threading and the Trying the thread tension is made more difficult to pull off the beginning of the thread. According to of the present invention, the thread end is now attached by twisting by a single or multiple thread loop is formed in the last thread runs that is twisted together.

In der Zeichnung' stellen Fig. 1 bis 7 schematisch die aufeinander folgenden Arbeitsvorgänge des Verfahrens dar. Fig. 8 und 9 deuten in Seitenansicht bezw. im Grundriß eine Einrichtung zur Durchführung des Verfahrens an.In the drawing 'Figures 1 to 7 represent schematically the successive operations of the method. Figs. 8 and 9 indicate respectively in side view. in plan a facility to carry out the procedure.

Die Herstellung der Spule erfolgt im dargestellten Ausführungsbeispiel, wie üblich, durch Aufwinden des Fadens 1 auf den von der Maschine in Drehung versetzten Dorn 2 unter Vermittlung des Fadenführers 3, der längs des Domes hin und her schwingt und eine Kreuz wicklung bewirkt. Sobald die Spule 4 die gewünschte Dicke erlangt hat, wird unter Vermittlung eines nicht gezeichneten Tasters oder einer anderen Einrichtung, z. B. einer durch die Umdrehungszahl des Wickeldornes beeinflußten Auslösevorrichtung, der Wickeldorn 2 in bekannter Weise stillgestellt. Vorher wird noch der Spule eine bandförmige Endwicklung 5, wie üblich, in der Mitte der Bobine durch Stillstellen des Fadenführers 3 oder durch Vergrößerung der Entfernung zwischen Dorn 2 und Fadenführer 3 erteilt. Nunmehr ist es notwendig, das Ende des Fadens 1 an der Mitte der Spule 4 zu befestigen.The production of the coil takes place in the illustrated embodiment, as usual, by Winding of the thread 1 on the mandrel 2 set in rotation by the machine with mediation of the thread guide 3, which swings back and forth along the dome and a cross winding causes. As soon as the coil 4 has reached the desired thickness, it is mediated a button (not shown) or another device, e.g. B. one through the The number of revolutions of the winding mandrel influenced the release device, the winding mandrel 2 in known Way immobilized. Before that, the bobbin is given a ribbon-shaped end winding 5, as usual, in the middle of the bobbin by stopping it of the thread guide 3 or by increasing the distance between the mandrel 2 and the thread guide 3. Now it is necessary to attach the end of the thread 1 to the center of the bobbin 4.

Gemäß der vorliegenden Erfindung ist nun ungefähr parallel zum Wickeldorn ein Stäbchen oder Finger 6 angebracht, der um den Spulendorn kreisen kann. Bei der Stellung Fig. ι ist angenommen, daß Wickeldorn 2 und Fadenführer 3 nach Fertigstellung der Spule 4 und der Schlußwicklung 5 zur Ruhe gekommen sind. Der Finger 6 beginnt nun seinen Umlauf um den Dorn 2 als Achse, und zwar in der Drehungsrichtung des Domes. Es ist jedoch auch die entgegengesetzte Drehungsrichtung möglich. Fig. 2 zeigt die Stellung der Teile, nachdem der Finger 6 eine halbe Umdrehung gemacht hat. Er ist dabei auf den Faden 1 getroffen und hat in diesem eine Bucht erzeugt. Durch Abwicklung des Fadens von der Spule oder durch Heranziehen des Fadens 1 aus der Spannvorrichtung wird hierbei die notwendige Fadenlänge gewonnen. Bei der Stellung Fig. 3 hat der Finger 6 eine volle Umdrehung gemacht und, wie man sieht, aus dem Faden 1 eine die Spule umfassende Fadenschlinge 7 gebildet. Er macht darauf eine weitere ganze Umdrehung in die Stellung Fig. 4 und bildet eine zweite Fadenschlinge 8. Nunmehr kommt eine Bürste 9 zur Wirkung, die zylindrische oder beliebige Form hat und an einem Schaft 10 sich befindet. Diese Bürste wird nun bei der Stellung Fig. 4 der Länge nach vorgeschoben (Pfeil v), während der Finger 6 still stehen bleibt. Die Bürste tritt dann über den Finger 6 und die auf diesem hängenden Schleifen 7,8 und hält letztereAccording to the present invention, a rod or finger 6 is now attached approximately parallel to the winding mandrel, which can rotate around the reel mandrel. In the position Fig. Ι it is assumed that winding mandrel 2 and thread guide 3 have come to rest after completion of the bobbin 4 and the final winding 5. The finger 6 now begins its rotation around the mandrel 2 as an axis, specifically in the direction of rotation of the mandrel. However, the opposite direction of rotation is also possible. Fig. 2 shows the position of the parts after the finger 6 has made a half turn. He hit thread 1 and created a bay in it. By unwinding the thread from the bobbin or by pulling the thread 1 out of the tensioning device, the necessary thread length is obtained. In the position of FIG. 3, the finger 6 has made a full turn and, as can be seen, formed from the thread 1 a thread loop 7 that encompasses the bobbin. He then makes another full turn into the position in FIG. 4 and forms a second thread loop 8. A brush 9 now comes into effect, which has a cylindrical or any shape and is located on a shaft 10. This brush is now advanced lengthways in the position of FIG. 4 (arrow v), while the finger 6 remains stationary. The brush then steps over the finger 6 and the loops 7, 8 hanging on this and holds the latter

Claims

back, while now the finger 6 is withdrawn lengthways in the direction of the arrow χ (Fig. 5). As soon as the finger 6 has left the brush 9, the shaft 10 is set in rotation (arrow W) and twists the two loops 7, 8 together. These loops are twisted so tightly into each other that the thread is not free again and the end is sufficiently securely attached to the bobbin. The Büsrte 9 now returns to its original position. The finger 6 moves forward again and the spindle 2 begins its rotation (arrow y) after the finished bobbin 4 has previously been pushed to the end of the dome 2 by the stripper in the usual manner. During the first rotations of the dome, the thread guide 3 can still stand still in a known manner, so that a collar-shaped initial winding is found in the middle of the point at which the new bobbin is now being formed. After the latter has been completed, the process of fastening the thread end occurs again, and when the bobbin is advanced after fastening, the bobbin 4 that has just been formed is pushed down from the end of the winding mandrel 2 and is thereby by a cutting device,. any type of thread between the bobbin 4 and the new bobbin seated behind it cut in a known manner. The finger 6 could also complete more than two turns before the brush comes into effect. The facilities necessary to carry out this operation are shown on the drawing in Fig. 8 and 9 in connection with a double-sided automatic winding machine with a stationary auxiliary shaft, in which the winding mandrel 2 is set in rotation by a drive device, not shown, which when the desired bobbins are reached thick, as usual, is immobilized while. at the same time a lateral standing auxiliary shaft 11 is set in rotation. From this auxiliary shaft, the devices for advancing the finished bobbin, cutting the thread, stopping and re-engaging the thread guide are set in motion in a known manner, whereupon the auxiliary shaft 11 automatically comes to a standstill. According to the present invention, a thumb 12 is attached to the shaft 11 which, when the shaft is rotated in the direction of the arrow ζ, initially acts on a double lever 14 articulated on the machine plate 13. This receives an oscillation which is transmitted to a shift lever 15, which rotates a gear 16 by a certain amount. A disk 18 in which the finger 6 is slidably mounted is thereby turned twice by a gear 17. The positions of FIGS. 1, 2, 3 and 4 are realized by the revolutions of the disk 18. During the further movement of the auxiliary shaft 11, the thumb 12 then strikes a second lever 19, the end of which engages in a sleeve 20 which is connected to the shaft 10. The sleeve 20 forms a friction coupling half 21 which is brought into engagement by the rotation of the lever 19 into engagement with a second coupling half on a disc 22 rotatable on the shaft 10, which is continuously rotated by a drive cord (not shown) from the main shaft of the machine is granted. In this way, the brush 9 is first advanced lengthways and then given a rotation, whereby the working stages of FIGS. 5 and 6 are realized. The finger 6 can be given the return movement by any device, for example a thumb, while it is being advanced by a spring. These tools can be modified in any way using the usual constructions.
