Definitions

  • the present invention relates to the winding of a thread in the form of a crossed spool on a textile machine, equipped with a winding system, in particular a spinning machine with released fibers. It relates to a process allowing the formation of a reel, with reserve thread, such that it can be unwound directly for weaving or knitting with great reliability. More particularly, the process of the invention relates to the formation of crossed coils on compressible tubes, said coils being intended for dyeing and being after dyeing unwound directly for weaving or knitting, without it being necessary to carry out a rewinding operation.
  • this ring consisting of approximately contiguous turns, in contact with the support in the zone constituting the spool itself, eliminates any massive detachment of thread, in bundle, during weaving or knitting.
  • the wire ring is made towards one of the ends of the support and in particular towards the end opposite to the zone where the reserve is located.
  • the spool being placed on the spool holder with the side of the reserve down and the wire being unwound upwards, it is preferable to minimize friction on the body of the support. place the ring towards the upper part of said support, therefore opposite the reserve.
  • the formation of the crossed coil is continuous, when the crossed winding, according to the formation of the ring, is carried out on the support with the same wire. It can be discontinuous, in particular in the so-called spinning looms with beginners, when in a first step we fill the support with the reserve and with the ring and we break the first wire to the right of the ring, then in a second step we attach a second wire, especially a wire during spinning, with the free end of said first wire.
  • the wire ring is for example produced, after formation of the reserve, by winding the wire along the support in a decreasing step up to the zone of formation of the ring.
  • the device for forming a coil of the starter by winding the wire on a support comprises a support drive drum and a wire placement arm having a displacement in an arc of a circle in front of the support in contact with the drive drum.
  • the drum has, opposite the part of the support close to the zone of formation of the ring, a surface having a hollow relief in the form of an endless screw and on the other hand for each coil of the starter the arm is stationary at first short, corresponding to the formation of the reserve, then it moves continuously to the zone of formation of the ring, and finally it is almost stationary in the zone of formation of the ring for a longer time.
  • the crossed coil of the invention is constituted by the winding of a wire around a support, with from the start to the end of the winding first a few turns of wire in an external zone of the support forming the reserve of reattaching, then a limited quantity of said wire in the form of approximately contiguous turns, and finally the actual cross winding.
  • the limited quantity of wire in the form of approximately contiguous turns corresponds to a number of turns comprised between 30 and 80 turns.
  • the approximately contiguous turns are located towards the end of the support opposite the reserve.
  • the example which will be described below relates to the formation of a crossed reel on a compressible tube on a spinning equipment known as a starter.
  • the compressible tube 1 shown in Figure 1 is a hollow plastic tube of generally cylindrical shape.
  • the main body 2 of the tube 1 is largely hollowed out, it comprises a network of cells 3 delimited on the one hand by annular elements 4 and on the other hand by connecting elements in the form of chevrons 5, connecting the elements annular 4, over the entire periphery of the tube 1.
  • the tube On either side of the central body 2, the tube has two planar annular ends 6,7 whose diameter is different from that of the central body 2.
  • the second end 7 has an outside diameter slightly greater than that of the central body and an inside diameter very slightly greater than the outside diameter of the first end 6, so as to allow the nesting of two successive tubes during dyeing.
  • a spinning material is said to start when the formation of the crossed reel is carried out in two distinct stages.
  • the tube is placed on a winding device where only the piecing reserve is made on this tube and a cross-wound pre-winding of a reduced quantity of wire.
  • the tube thus filled is placed on the actual spinning loom where the free end of the pre-wound wire is sought by a nozzle and attached to the wire in training on the loom.
  • the crossed pre-winding represents about 70 meters of wire, that is to say a quantity sufficient for this pre-winding to constitute a relatively complete covering of the cells favoring the gripping action of the end. free of thread by suction from the squeegee.
  • FIG. 2 shows the packed tube according to the invention after the first step has taken place.
  • the reattachment reserve 7 is formed in the form of a few contiguous turns; the free end 9 of the thread 10 on the reserve side, blocked under a few turns, is available for attaching it to weaving or knitting with the start thread of another spool.
  • the wire 10 is wound in the form of an accumulation of approximately contiguous turns constituting the ring 11.
  • the free end 12 of the wire 10 at the level of the ring 11 is not blocked, it is available for connection with the wire being formed in the second step.
  • the wire 10 is wound in a helix with a pitch which decreases from the reserve 9 to the ring 11.
  • the reattachment system integrated into the machine connects this end 12 of the wire 10 to the wire being formed, and the cross winding of this wire around the central body 2 of the tube 1 continues so conventional.
  • the rotation of the spool on the spinning machine is obtained by rotating rollers generally made of rubber, on which the external surface of the tube or of the spool being formed is applied.
  • the quantity of wire 10 pre-wound on the same tube 1 was for the invention from 12 to 15 meters, compared to the usual 70 meters of pre-winding.
  • the pre-winding according to the invention requires significantly less yarn than according to the conventional method. This has a double advantage. On the one hand, the time for producing this pre-winding is reduced accordingly and the productivity of the machine is improved. On the other hand, in the event of an error in the choice of the yarn 1 constituting the pre-winding, the defect in weaving or knitting due to this error will be reduced by the same amount.
  • the pre-winding of the first step is carried out on the device shown very diagrammatically in FIG. 3.
  • This device comprises a drive drum 13, which is a cylinder rotating around its horizontal axis 14. It also includes an arm 15, mounted pivoting about an axis 16. The arm 15 is terminated by a clamp 17, able to grip the wire and move it during the pivoting of the arm 15.
  • a clamp 17 able to grip the wire and move it during the pivoting of the arm 15.
  • the drum 13 has its outer surface which has a hollow relief in the form of an endless screw.
  • the operation of the device is as follows.
  • the tube 10 is applied against the drum 13, with the annular end 6 corresponding to the reserve placed on the side where the arm 15 is in the high position.
  • the wire 10, coming from a reel not shown and held by the clamp 17, is presented by the arm 15 on the tube 1 according to the following sequence.
  • the arm 15 remains opposite the annular end 6, during the winding of the first few turns of the connecting reserve 9.
  • the arm 15 pivots about its axis 16 describing an arc of circle, in front of the tube 1 and the drum 13, this circular arc passing in front of the line of tangency 18 of the tube 1 and of the drum 13 towards the central part of the central body 2 of the tube 1.
  • the wire 10 is wound around the tube 1 first at an important step and then at a decreasing step until the arm is in the low position.
  • the third step corresponds to the end of pivoting of the arm 15; the wire 10 is wound according to the approximately contiguous turns for a determined time to constitute the ring 11, then it is cut.
  • the invention is not limited to the embodiment which has been described in a non-exhaustive manner, but covers all variants thereof.
  • the tube can be designed so that the deformation of the compressed tube is mainly in the middle part of the central body of the tube; in this case, the ring will preferably be placed towards one of the ends of the central body in an uncompressed part so that it is well irrigated by the dye bath passing through the cells from inside the tube.
  • the invention is not limited to dyeing reels on compressible tubes.
  • the ease of grip of the end of the wire by the nozzle, resulting from the position of this end on the ring, is such that the invention proves to be advantageous even for non-compressible coils.
