Definitions

  • the present invention relates to a method and a device for spinning core wires.
  • Core threads in which a core thread is wrapped in a sheath of staple fibers are known. Processes for obtaining core threads are described in particular in the patents of the United States of America No. 1,373,880, 2,024,156, 2,210,884, 2,313,058, 2,504,523, 2,526,523, 3,017 740 and 3,038,295.
  • yarns with spun cores generally have the disadvantage of being limited in the production speed to that of the empbyés machines and therefore to the twisting system used.
  • Self-twisted yarns obtained by natural twisting in one direction and in the other of two strands having previously received an alternating right and left twist are also known.
  • a process for the manufacture of self-twisted yarns on a self-twisting loom and various applications are for example described in British patents Nos. 1,015,291, 1,121,942 and 1,084,371.
  • the object of the present invention is to enable the production of core yarns with an extremely high production speed, obtained by suppressing the variations in tension inherent in self-twisted core yarn systems.
  • a process for spinning core yarns a process in which at least one strand of fibers is stretched between a point of supply of this strand and a pair of stretching cylinders, upstream of which a filament is optionally introduced.
  • the strand formed by the wick of fibers and optionally the continuous filament is twisted with at least one strand formed by a continuous filament and possibly a wick of fibers, by a friction torsion member by introducing them in the same point of convergence upstream of the torsion member, the tension of the strands is adjusted before the winding by passing them, after the twisting member, through a pair of delivery cylinders and twisting after bobi swims the wire thus formed by the strands on a twisting loom.
  • the continuous core wires are optionally supplied with constant voltage.
  • the wire formed by the strands is twisted on a conventional twisting loom, for example with a slider ring or a double twist to give the final twist.
  • one or more strands of fibers are stretched separately between supply points and pairs of stretching cylinders, the continuous core wires are optionally supplied with constant tension, they are introduced into said strands upstream different stretching cylinders, and the strands formed at one point of a torsion member are made to converge before the assembly is wound. The assembly formed by the strands is then put on a twisting loom to give the final twist.
  • a spinning process is carried out by stretching a wick of fibers 5a between a supply point 2a and a pair of stretching cylinders 4a.
  • the drawing system further comprises a pair of drawing sleeves 3a.
  • a wick of fiber 5b is stretched separately by a drawing system comprising a supply point, namely a pair of food cylinders 2b,. a pair of drawing sleeves 3b and a pair of drawing cylinders 4b.
  • At least one continuous filament (6a, 6b) is introduced upstream of the stretching cylinders (4a, 4b) at least one continuous filament (6a, 6b) is introduced.
  • the tension of these filaments is adjusted by tension adjustment means 19a, 19b, for example the cylinder and strap devices 19a, 19b. Two strands are therefore formed, each consisting of a wick of fibers and a filament.
  • the strands thus formed are twisted together by a wringer 7 and are guided by two guides 8 and 9.
  • the two strands then pass through a pair of cylinders 10 before being wound on a cylinder 11.
  • the strands are wound on the cylinder 11. Then, in a subsequent step, the strands are twisted on a twisting loom for example.
  • this residual alternating twist is sufficient to ensure cohesion without having the sliding of the covering fibers relative to the core which makes it possible to twist this thread on a conventional twisting loom.
  • good results have been obtained with the 2x25 Tex wire described above on a double twist loom with a spindle speed of 11,000 rpm and a twist of 350 rpm, a development of 62.8 m per minute.
  • the assembly of the two strands before the twister 7 is important in the sense that it serves as a voltage regulator. Indeed, as shown in Figure 3 where the position 13 of the point of convergence represents the average position, position 14 corresponds to the point of convergence when there is a size in one of the two strands where less torsion is communicated. by the twisting organ. Position 15 corresponds to the point of convergence when there is fineness in the strand.
  • the assembly of the two strands is also necessary according to the invention, since the cohesion between the strands makes it possible to keep the alternating twist on each of the strands, which has the effect of preventing the fibers from sliding on the filament.
  • This phenomenon can also be used, advantageously, in order to detect the presence or absence of cover wires on the core by the variation of the point of convergence. Indeed, if for some reason the coverage of the fiber sheath runs out, for example during a breakage of the wick of fibers, the point of convergence 15 will go up very high, for example, it will go up to the point 15a, the position of which of course varies according to the tension settings.
  • a contactor 26 is placed between point 15 and point 15a, on the axis joining the points of convergence 13, 14, 15, 15a, when the fiber in the wick of fiber runs out, the ascent of the point of convergence 15 towards point 15a causes the switch 26 to toggle.
  • This contactor can then actuate various commands, for example commands for supplying fiber filament, or commands for raising the yarn take-up reel 11, or even l stop of the twisting member 7, etc.
  • the presence or absence of a strand formed either of a single strand of fiber or of a strand of fiber and of a continuous filament is detected by varying the position of the wire 18 formed in upstream of the twisting member 7 (see FIG. 3).
  • two contactors 27, 28 are placed located on either side of the wire 18, upstream of the twisting member 7.
  • the strand 5b , 6b takes a position 5'b, 6'b between the stretching cylinder 4b and the twisting member 7. This position which is displaced outwards relative to the line formed by the points 13, 14, 15, 15a a then tend to move the contactor 28, which acts as the contactor 15a.
  • the strand 5a 6a moves outward relative to the line of the points of convergence 13, 14, 15, 15a and then acts on the contactor 27 which itself acts on the control means making it possible to stop the supply of filaments, fibers, etc.
  • a core wire which does not have any discontinuity, such as knots, splices or stops and which allows the production of coils of wire of significant weight, for example having a weight of at least 1 kg for fine threads, for example around 10 tex and spools of thread of at least 10 kg for coarse threads, for example for threads around 1000 tex.
  • FIG. 2 represents an example of a wringer 7 which can be used without limitation, or as indicated in French patent No. 1,147,515 (American patent No. 2,943,433), plans to pass the twisting yarn between two endless, movable belts (16, 17), these belts being arranged obliquely to each other so that the yarn 18 is given an impulse in the direction of its movement during its passage between the belts.
  • the drawing sleeves (3a, 3b) and the drawing cylinders (4a, 4b) there is a condenser 20 known per se which is used to condense the fibers on the continuous filament.
  • the filament is introduced into the center of the wick of fibers and then downstream of the drawing line 22, the strand receives the twist which ensures the attachment of the fibers to the filament. In the case of very high speed, it may happen that the twist is not sufficient to ensure the attachment of the outside fibers of the web. This results in a significant loss of fiber.
  • a variant of the invention is such that one can work on a larger number of stretching systems than that described in FIG. 1.
  • Another important variant is that one can work on one of the strands, with an assembly composed of a continuous filament and a sheath of fibers while another strand is composed only of a continuous filament. .
  • good results have been obtained, at the speed of 200 meters per minute, with a resultant 71.5 tex thread, composed of a 72 decitex core and a fiber sheath on one of the strands. and a continuous filament of 72 decitex on the other strand.
  • a third variant is that one can work on one of the strands, with an assembly composed of a continuous filament and a sheath of fibers while another strand is composed only of a sheath of fibers, provided that there are enough fibers in section. We therefore delete a continuous filament, for example filament 6b.
  • a fourth variant is that one can work on one of the strands composed of a continuous filament, while the other strand is composed only of a sheath of fibers, provided that there is sufficient fibers in section. There is then a single continuous filament, for example the filament 6a and a single sheath of fibers, for example the sheath of fibers 5a.
