Definitions

  • this wire in unwinding rubs on the periphery of the upper reel so that it is braked. Consequently, it is not placed parallel to the other wire with the same tension and it moreover tends to come to wind around the axis of the spindle while passing under the second reel which involves, of course its rupture.
  • the turns of the upper coil which are not retained by the disc risk collapsing and breaking due to the appearance of a capstan phenomenon around the axis of the spindle.
  • the coil is generally placed on a sheepskin which does not prevent the turns from collapsing.
  • German patent application DE-A 62 827 814 a disc whose periphery is provided with elastic lamellae. However, these can only deform if the thread tension is sufficient. Furthermore, the deformation of said strips is not automatically a function of the diameter of the upper coil.
  • the improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a device capable of guiding the unwinding of the wire from the lower spool, varying in diameter as the reduction in that of the upper coil, independently of the tension of the thread and without generating any antagonistic action towards it.
  • a double twist spindle 1 supporting as usual a pot 2 in which are arranged, one above the other, two coils 3 and 4 kept fixed relative to the axis 5 of the spindle 1 From the coils leave two wires 6, 7 which are engaged in the central bore 5a of the axis 5 so as to be assembled with each other before the twisting. We see the two wires joined below the figure, at their exit from the bore 5a.
  • a device according to the invention is given under the upper coil 4, given the general reference 8, and which cooperates with the periphery of the base of the coil 4.
  • the device 8 has been shown in FIG. 1 in the position it occupies when the coil 4 is full while in fig. 2 its position corresponds to the end of the unwinding of the coil wire.
  • the device 8 essentially comprises on the one hand a disc 9 angularly immobilized with respect to the axis 5 which is itself stabilized in rotation as is well known in the twists, and on the other hand a corolla 10.
  • the periphery of the disc 9 comprises a shoulder 9a facing outwards and in which is arranged a multiplicity of cylindrical blocks 11 each comprising means for retaining the ends of two arches 12 which intertwine to form the corolla 10. All of the blocks 11 is retained in the shoulder 9a of the disc by means of an elastic circular ring 13 such as an elastic, a spring or the like which is braided with respect to the arches 12 as best seen in FIG. 4. In fact the rod 13 passes alternately in front of and behind the ends of the arches 12 associated with two consecutive blocks 11.
  • the rod 13 cooperates with the ends of the arches 12 and the top of the blocks 11.
  • the hoops can be made by means of strands of resistant plastic material such as "nylon” or the like and their ends can be engaged in blocks 11 also made of plastic with respect to which they are welded or otherwise fixed.
  • the elastic ring 13 plates the various blocks 11 at the bottom of the shoulder 9a of the disc 9, this shoulder affecting the most appropriate shape.
  • the shoulder 9a could also be rounded so as to better cooperate with the periphery of the blocks.
  • the ply in question decreases in diameter and the corolla 10 of the device 8 closes little by little while keeping contact with its periphery.
  • the wire 6 which is unwound from the lower coil 3 cooperates with the periphery of the corolla and not point with that of the coil 4 so that the resistance to its running is practically zero.
  • friction on the corolla does not risk generating on the wire 6 tensions which would hinder its proper assembly with the wire 7 coming from the upper coil 4.
  • corolla 10 could be produced by any other means than that of arches 12 associated with blocks 11; by way of nonlimiting example, a corolla made up of petals that deploy or retract like the diaphragm of a camera can be cited.

Claims (8)

1. Vorrichtung zur Steuerung des Abrollvorgangs eines Fadens (6), der von einer Spule (3) ausgegeben wird, die unter einer anderen (4) in dem Topf (2) einer Zwirnspindel (1) angeordnet ist, wobei die Vorrichtung mehrere elastische Lamellen aufweist, die am Umfang einer Scheibe angeordnet sind, welche sich zwischen den beiden Spulen (3, 4) befindet und die durch die Spannung des Fadens (6) nach oben verformt werden, dadurch gekennzeichnet, dass die Vorrichtung Mittel (9, 10, 13) aufweist, durch die der Durchmesser des Umfangs der Lamellen automatisch in Abhängigkeit vom Durchmesser der oberen Spule (4), unabhängig von der Grösse der Spannung des Fadens (6), variierbar ist.
2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die automatische Veränderung des Durchmessers des Umfangs der Scheibe durch ein elastisches Element erreicht wird, das die Lamellen an dem Umfang der oberen Spule (4) zur Anlage bringt.
3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, dass die Scheibe (9), die zwischen den beiden Spulen (3, 4) angeordnet ist, in Höhe ihres Umfangs miteinander verschlungene, kleine Bögen (12) trägt, die ein blütenkranzartiges Gebilde (10) darstellen, das mit einem kreisrunden, elastischen Rohr (13) verbunden ist, durch das die kleinen Bögen (12) mit Spannung beaufschlagt werden, so dass sie dazu neigen, sich gemeinsam nach oben zu verschwenken.
4. Vorrichtung nach Anspruch 3, dadurch gekennzeichnet, dass der Umfang der Scheibe (9) eine Schulter (9a) aufweist, in der nebeneinander einen kreisrunden Querschnitt aufweisende Blöcke (11) gehalten werden, von denen jeder eine Verbindung zweier Enden der kleinen Bögen (12) bildet.
5. Vorrichtung nach Anspruch 4, dadurch gekennzeichnet, dass die die kleinen Bögen tragenden Blöcke (11) in der Schulter der Scheibe durch das Rohr (13) gehalten werden, das durch die Arme der kleinen Bögen (12) hindurchgeflochten ist.
6. Vorrichtung nach Anspruch 5, dadurch gekennzeichnet, dass die nach oben gerichtete Wirkung des Rohres (13) auf die Anordnung der kleinen Bögen (12) aufgehoben wird, wenn das blütenkranzartige Gebilde (10), das sie bilden, unter der Wirkung einer abwärtsgerichteten Schwenkbelastung einen instabilen Gleichgewichtspunkt durchfährt, wobei die Schwenkbelastung dann in Richtung nach unten unterhalb dieses Punktes sich auswirkt.
7. Vorrichtung nach Anspruch 6, dadurch gekennzeichnet, dass das blütenkranzartige Gebilde (10) an dem Umfang (9b) der Scheibe (9) zur Anlage kommt, wobei der Raum oberhalb letzterer vollständig freigegeben wird, um das Einsetzen einer anderen Spule (4) zu erleichtern.
8. Vorrichtung nach Anspruch 4, dadurch gekennzeichnet, dass Mittel (14, 14a, 11a) vorgesehen sind, durch die die Blöcke (11) in der Schulter (9a) der Scheibe (9) zurückgehalten werden.
