Definitions

  • the present invention relates to improvements made to the coronelles, that is to say to the devices placed at the top of a double twist spindle so as to slow down the running of the wire.
  • Such devices are well known in practice and it is known that their rotation must be slowed down by weights or springs, so that during the unwinding of the reel, the wire is braked.
  • the thread to be twisted comes out of the spindle in the usual way through a radial hole opening onto a disc on the periphery of which a thread reserve is established before the latter forms the usual twisting balloon. It is easily understood that there must be a balancing of the thread tensions which appear at its exit from the radial hole of the spindle and at its entry into the bore of the latter. In particular, if the thread tension is such that the reserve which takes place on the disc is large, it can cause a capstan effect which causes an unacceptable high tension to the point that we can witness the elimination of the balloon. and even breaking the wire.
  • the improvements which are the subject of the present invention aim to remedy the aforementioned drawbacks and to allow the production of a coronelle comprising a simple and effective device for varying its resistive torque as a function of the diameter of the coil.
  • FIG. 1 Schematically illustrated in FIG. 1 the main parts of a double twist spindle having a rotating axis 1, provided with a central bore 1a with respect to which a coil 2 remains angularly fixed by known means, said coil being placed in a pot 3 of cylindrical shape.
  • the disc 4 located under the pot 3 and which rotates with the spindle 1 has been illustrated by a broken line. It has a radial hole issuing from this bore and opening onto a peripheral surface of said disc.
  • the wire 5 coming from the coil 2 passes through the bore 1, crosses the radial hole of the disc 4 to form a balloon 5a around the pot 3.
  • Two methods are used to regulate the tension of the thread 5; the first consists in providing a wire brake inside the bore 1a, while the second is characterized by the use of a coronelle 6 mounted with free rotation relative to the axis 1 and which is associated with a device ensuring the creation of a constant or variable resistant torque.
  • the coronelle 6 is associated with a hub 7 mounted for free rotation about the axis 1. It is produced by means of two symmetrical sections of steel wire, as illustrated in FIG. 2. Each of these sections has a rounded central part 6a which encloses the hub 7 in a groove 7a thereof and two branches 6b, 6c, one of the ends of which has a hook 6d, 6e. The two sections are applied against each other and the free ends of the branches 6c are welded against the corresponding part of the branches 6b so that the two central parts 6a of the two sections are located in the same plane.
  • each hook 6d, 6e of the coronelle 6 are each intended to hold a sleeve 8 respectively 9 oriented perpendicular to the general plane of this coronelle, so that in practice the sleeves 8, 9 are oriented vertically when the coronelle is in place. It is further observed that each hook 6d, 6e is extended by a thread guide 6f, 6g whose role is illustrated in FIG. 1, that is to say, it serves to guide the wire 5 between the periphery of the coil 2 and the bore 1 a of the axis 1.
  • each of the sleeves 8, 9 is embedded one end of a loop formed by an elastic funicular element having low rigidity.
  • This element can advantageously be produced by means of a superpolyamide horsehair, the term horsehair designating a single extruded wire.
  • This horsehair forms a loop 10 which, due to the embedding of its ends in the vertical sleeves 8 and 9, is in the free state. of the coronelle in the plane of symmetry thereof. If one chooses as material for making the loop 10 a material such as "Nylon •, it is easily understood that due to its low rigidity, if the loop 10 is offset laterally, it tends to return elastically in the plane of symmetry of the coronelle. However, this loop also has a certain flexibility which allows it, when the coronelle is put in place, to surround part of the periphery of the coil 2.
  • the loop 10 Since thanks to its elastic qualities and the braking effect due to its friction against the periphery of the coil, the loop 10 generates braking of the coronelle which is more important when the diameter of the coil is large than when it is low. In other words the resistive torque applied to the coronelle decreases as the diameter of the coil 2 is reduced.
  • the resistive torque can be varied and adapted to the diameter and quality of the wire 5 wound on the spool 2.
  • a coronelle with variable resistive torque has thus been produced, the action of which is particularly effective and the cost price excessively low.
