Definitions

  • the present invention relates to a method for joining two strands of yarn in which, firstly, a portion of said strands is untwisted, this twisting creating an over-twist in the rest of said strands, the strands being cut so as to form a barb of fibers to the end of each strand; secondly, the ends of the two strands to be brought into contact are brought into contact by making the fibers of the two barbs interpenetrate and, thirdly, said ends are twisted so as to recreate the twist of the wire and to link the two strands together .
  • the invention also relates to a device for implementing the method, said device being designed to arrange the fibers of each barb substantially in a plane in an elongated shape, to put the two barbs one on the other and to penetrate a part of the fibers of the end zone of each beard in the other beard.
  • the object of the present invention is to remedy the drawbacks of these solutions and to make it possible to make practically invisible connections and of high strength, in particular for large yarns made of synthetic fibers.
  • the subject of the present invention is first of all a method for joining two strands of wire in which, in the first place, a portion of said strands is untwisted, this distortion creating an over-twist in the rest of said strands, the strands being cut to form a fiber barb at the end of each strand; secondly, the ends of the two strands to be brought into contact are brought into contact by making the fibers of the two barbs interpenetrate and, thirdly, said ends are twisted so as to recreate the twist of the wire and to link the two strands together .
  • This process is characterized by the fact that, after having untwisted a portion of the two strands to be joined, the fibers of each beard are arranged substantially in a plane in an elongated shape whose maximum width is substantially greater than the diameter of the wire and is located in an area close to the base of the beard, then decreases to its end; the aforementioned cut is made from the end of the beard to a given length from its base; we put the two barbs on top of each other so that the end of each of them is opposite the widest area of the other beard, and we penetrate a part of the fibers from the end zone of each beard into the other beard.
  • This invention also relates to a device for implementing this method, this device being designed to arrange the fibers of each beard substantially in a plane in an elongated shape, to put the two beards one on the other and penetrate part of the fibers of the end zone of each beard into the other beard.
  • This device is characterized by the fact that it comprises two plates movable between two positions, one where they are separated and the other where they are adjacent.
  • each plate having a flat surface bordered laterally by two flanges and one end of which is adjacent to a distribution slot connected to a source of pressurized air, a cylindrical housing opening into this flat surface and receiving a cone whose point is adjacent to this surface, this housing being connected to said source by a conduit opening laterally and directed against the axis of said cone, said distribution slots being at opposite ends of these plates when they are adjacent to each other .
  • the advantage of the invention lies in the fact that it makes it possible in particular to obtain excellent results in terms of resistance as well as in that of appearance with relatively large threads and especially when they are formed. synthetic fibers in which the residual twist manifests itself more than with natural fibers.
  • the device illustrated in FIG. 1 has a frame 1 which has two supports 2 and 3 pivotally mounted in the frame 1 by means of two hollow shafts 4 and 5. These two supports 2 and 3 are connected to each other by a connecting rod 6 of which the ends are articulated to the supports by shafts 7 and 8 parallel to the hollow shafts 4 and 5.
  • the shaft 8 is also associated with the rod 9 of a jack 10 intended to rotate the supports, kinematically connected by the rod 6 around axes of the hollow shafts 4 and 5, so as to move the supports from the position illustrated in FIG. 1 to a position in which the supports 2 and 3 are aligned.
  • the two hollow shafts 4 and 5 give way to two other shafts 11 and 12 which extend to behind the frame 1.
  • Each shaft 11 and 12 is integral with a pinion 13, respectively 14. These pinions are connected by a toothed belt 15.
  • the front end of each shaft 1 1, 12 passes through one of the supports 2, respectively 3 and is integral with a bevel gear 16, respectively 17 engaged with two bevel gears 18, respectively 19.
  • Each bevel gear 18, 19 is integral with a pin 20, respectively 21 mounted between two parallel flanges 2a, 2b respectively 3a, 3b of the supports 2 and 3.
  • Each pin 20, 21 ends in a disc 22 respectively 23 split radially.
  • the rear end of the shaft 11 is still secured to a second pinion 24 engaged with a rack 25 secured to the rod 26 of a jack 27.
  • This drive mechanism 24 to 27 is used to control the rotation of the pins 20 and 21 in opposite directions to each other, the spindle 21 being driven by the belt 15 connecting the pinions 13 and 14.
  • Two suction tubes 28, 29 respectively 30, 31 are fixed in the frame 1 on either side of each support 2 respectively 3. These tubes are connected to the intake of a fan VE, and are arranged two to two so that a wire stretched between each pair of suction tubes bears against the edge of the discs 22, respectively 23 and passes adjacent to a plate 32, respectively 33. Each plate 32, 33 is integral with the support 2, respectively 3 .
  • the plate is made of an insulating material, for example a plastic material. Its upper face has a central channel 34, the bottom of which serves as a bearing surface for spreading the fibers forming the beard of the end of the strand of the wire to be attached. The depth of this channel is of the order of 0.3 mm.
  • the surface of the plate 32 bordering the channel 34 is covered with a layer 35 of a plastic material more flexible than that of the block and intended to act as a seal when the two blocks are in the position illustrated by the fig. 2. The thickness of the layer 35 is of the order of 0.1 mm.
  • This plate 32 further comprises an intake duct 36 connected to a source of pressurized air VE 2 (fig. 1) capable of being heated using an electrical resistance 38.
  • This intake duct 36 communicates with a distribution chamber 39 which opens at the bearing surface delimiting the bottom of the channel 34 by forming a nozzle 40 through a slot whose length corresponds substantially to the width of the channel 34 and one of the lips 41 parallel to the bottom of the channel 34, maintains the jet of the nozzle 40 along the bearing surface of the channel 34.
  • FIG. 3 shows that the width of this channel is not constant. If we observe from the outlet of the nozzle 40, we see that it widens over approximately 1/4 to 1/5 of its length of approximately 40% of its initial width and that then it returns gradually to this initial width over the rest of its length.
  • the bearing surface of the bottom of the channel 34 in its part corresponding to the portion where this channel widens at the outlet of the nozzle 40, has an opening which corresponds to a cylindrical housing 42 which crosses the plate 32 perpendicular to the bottom of the channel 34.
  • This cylindrical housing 42 receives a rod 43 adjusted by friction and the upper end of which ends in a cone 44 whose point arrives just at the bottom of the channel 34.
  • a conduit 45 centered on the axis of the cone 44 and located approximately 1/3 of the height of this cone from its base makes the cylindrical housing 42 communicate with the distribution chamber 39.
  • This plate 32 further comprises a series of electrical conductors 46 arranged trans crosswise to channel 34 and spaced apart longitudinally. These electrical conductors are located near the bearing surface of the bottom of the channel 34 and are embedded in the plastic of the plate 32 so that a dielectric separates these electrical conductors 46 from this bearing surface. These conductors are connected to a GE electrostatic generator.
  • Each plate 32, 33 carries on its lateral face adjacent to the end of the channel 34, a cutting blade 48, respectively 49 while a second cutting blade 50, respectively 51 is fixed to the frame 1 in the respective paths of the blades 48, 49 described during the displacement of the supports 2 and 3 from the position illustrated in FIG. 1 in the position in which the plates 32 and 33 are brought one against the other.
  • the two strands of wire to be attached are each brought opposite the two suction tubes 28, 29 respectively 30.31, all four connected to the intake of the fan VE 1 , so that the portions of wire held between the suction tubes 28, 29 respectively 30, 31 are stretched and press against the discs 22, respectively 23.
  • the functions are indicated by 0 and 1, 0 corresponding to a rest or starting position of the member performing the function and 1 a position in which the member is moved away from its rest or resting position. departure. From time t o to time t "the function a corresponds to the rotation of the discs 22, 23 integral with the pins 20, 21.
  • the blowing of air begins through the nozzle 40 (function b), the untwisted wire being applied against the bearing surface of the bottom of the channel 34 is therefore subjected to this jet which eliminates the fibers which do not are not integral with the strand of wire wound around each spindle 20, 21.
  • the blown air is air heated by the heating body 38. Its temperature is of the order of 60 ° to 90 ° C and is intended to suppress the residual twist of the fibers so as to spread the fiber barb on the bearing surface of the bottom of the channel 34 and so that these fibers remain substantially adjacent to the plane of this surface.
  • the fibers forming a beard at the end of a untwisted yarn retain, after the untwisting, part of the deformation resulting from their twisting and thus cannot be spread over a surface.
  • the hot air eliminates all or part of the deformation of the fibers.
  • the air flow, formed by the nozzle 40, adjacent to the bottom of the channel 34 extends the beard of untwisted and heat-treated fibers at the bottom of this channel 34.
  • the secondary air jet formed through the duct 45 cleaning between the distribution chamber 39 and the housing 42 is directed against the cone 44 and deflected into the main air flow from the nozzle 40. It has the effect of creating a widening of the main jet and a corresponding widening of the beard fiber.
  • the side walls of the channel 34 narrow towards the open end of this channel and cause a tightening of the flow and the fibers.
  • the fiber beard spread at the bottom of the channel 34 has substantially the shape of a flame, but we will see later that this shape is of great importance for the quality of the piecing.
  • the conductors 46 are energized (function c) by the electrostatic generator GE creating a field between these conductors 46 and the rest of the device being at ground potential.
  • the thickness of the dielectric separating these conductors from the bottom of the channel 34 must be small, otherwise the fibers could not be electrostatically charged.
  • the thickness of the dielectric is of the order of 0.3 mm.
  • the same result could be obtained pneumatically by sucking air through the conduits 52.
  • the two channels 34 form a single passage open at both ends.
  • the additional thickness resulting from the layers 35 forms an opening of approximately 0.5 mm between the bottom of each channel 34 and the respective deflectors 41 allowing the passage of the wire.
  • the function c corresponding to the electrostatic field is stopped and at time t 8 the disks 22 and 23 are returned to their starting position (function a), that is to say that they are rotated in opposite directions by the return stroke of the rod 26 of the jack 27.
  • the overvoltage induced in each strand of wire wound around the pins 20, respectively 21 during the initial untwisting is transferred into the barbs whose fibers are 'interpenetrate so that a structure very close to the spinning is created at the place of the piecing.
  • each strand of wire is unwound from its respective pin 20, 21, it is released from the radial slot of the discs 22, respectively 23.
  • the joining process described does not include any mechanical element acting as a means of implementing the method, the mechanical means acting only as control elements, therefore indirectly.
