Definitions

  • This invention relates a non-contact doubling and twisting apparatus, with which both the twisted yarn and the filament yarn or the spun yarn can be doubled and twisted by using a fly disc of a two for one twister for a filament, and, more particularly, a non-contact doubling and twisting apparatus, wherein as yarn is input into a top guide by the disc hole of a fly disc since a yarn guide is newly mounted between a tenser and a top guide placed on the top of a spindle by converting the yarn guide of the two for one twister and it is designed to pass through a slot of a hollow, a yarn-twisting zone, at a non-contact state, a non-contact doubling and twisting apparatus can perform high speed doubling and twisting operations as well as it can take an advantage of a covering effect.
  • doubled yarn which gets unwound from a bobbin is input into a top guide 3, is twisted passing through a tenser 5 having a hollow and a yarn guiding pipe 26, passes through an eyelet 8 and is wound on a cylinder 13,
  • This invention is intended to increase the efficiency of doubling and twisting operation by guiding yarn into a yarn-twisting zone at a non-contact state as well as to improve unwinding characteristic at the time when the doubled yarn which is combined with more than two kinds of yarn gets unwound from a bobbin in the two for one twister for a filament.
  • this invention Compared with the conventional method, this invention has much improved productivity and much simplified operation and can reduce production cost. Also, as this invention can result in a covering effect relatively easily by endowing doubled yarn made of more than two kinds of yarns with many twisting operations, it is intended to provide a covering yarn.
  • a non-contact doubling and twisting apparatus which is characterized by further comprising a yarn guide 20 having a fly disc 4 which is located between a top guide 3 and a tenser 5, mounted to be rotated freely and has a disc hole 12 through which doubled yarn can pass.
  • a non-contact doubling and twisting apparatus in a double twister wherein yarn guide 20 is integrally formed with a top guide holder 16 having a through hole, a cover 17 for fixing the top guide holder and a fly disc 4 having a disc hole 12, and wherein a ball bearing 15 is mounted in the inner circumferential surface of a cover 17, and a fly disc shaft 14 having a through hole which is connected with the through hole of the top guide holder 16, is inserted into the said ball bearing 15, so that the inner circumferential surface of the said ball bearing 15 gets in contact with the outer circumferential surface of a fly disc shaft 14.
  • a non-contact doubling and twisting apparatus in a double twister according to claim 1, wherein a disc hole 12 is rotated circumferentially having the same diameter as or longer diameter than the maximum diameter of a yarn winding layer wound on a bobbin 1 or the diameter of a tenser disc 6.
  • FIG. 1 is a flow diagram showing the entire configuration of a two for one twister for a filament of this invention.
  • the doubled yarn 2 which is made of more than two kinds of yarn and wound on a bobbin 1, passes through a disc hole 12 of a fly disc 4, is input into a ceramic top guide 3, and is twisted passing through a tenser 5 having a hollow and the yarn guiding pipe 26.
  • the yarn guide 20 is connected to the top of a tenser 5 by a fly disc shaft 14 which can be inserted to be connected to the tenser 5 screwed on the top of a yarn guiding pipe 26. Also, there is a disc hole 12, through which the supplying yarn 2 can pass, on a round shaped fly disc 4, which can be freely rotated. The supplying yarn 2 which is to be unwound from the bobbin can be easily unwound by the rotating force of the fly disc 4 and the unwound yarn can pass through the rotating disc hole 12 and be input into the top guide 3.
  • the spindle 7 is rotated by a flat belt 9 to which a driving force of a motor (not shown in the drawing) is delivered.
  • the marks 24, 24' are guide rollers for winding the doubled yarn, the number 25 is a tension adjustment and the number 18 is a tenser holder
  • FIG. 2 through FIG. 4 show a yarn guide 20 which is used for the non-contact doubling and twisting apparatus in a double twister of this invention, wherein yarn guide 20 is integrally formed with a top guide holder 16 having a through hole, a cover 17 for fixing the top guide holder and a round-shaped fly disc 4 having a disc hole 12 through which the yarn can pass, and wherein a ball bearing 15 is mounted in the inner circumferential surface of a cover 17, and a fly disk shaft 14 having a through hole which is connected with the through hole of the top guide holder 16, is inserted into the said ball bearing 15, so that the inner circumferential surface of the said ball bearing 15 gets in contact with the outer circumferential surface of a fly disc shaft 14. Also the ceramic top guide 3 is inserted into a through hole of the top guide holder 16.
  • the disc hole 12 placed on the fly disc 4 is rotated circumferentially having the same diameter as or longer diameter than the maximum diameter of the winding layer wound on the bobbin 1 or the diameter of a tenser disc 6.
  • the doubled yarn 2 which is wound on the bobbin 1 is input into the top guide 3 after passing through a disc hole 12.
  • the fly disc 4 is rotated continuously by the tension of the yarn 2 which is input into the top guide 3.
  • the yarn 2, which gets unwound from the bobbin 1 is not contacted with a tenser disc 6 and the yarn which is wound on the bobbin is unwound smoothly.
  • the ballooning tension between the eyelet 8 and the snail wire 11 is maintained equally and the outer circumference of the fly disc 4 smoothes yarn-guiding operation between the snail wire 11 and the eyelet 8.
  • the yarn is guided by the disc hole 12 which is rotated circumferentially having the same diameter as or longer diameter than the maximum diameter of yarn winding layer wound on the bobbin 1 or the diameter of a tenser disc 6, the supplied yarn is unwound easily from the bobbin by the rotation of the fly disc 4. Also, the unwound yarn is not contacted with the yarn winding layer or the tenser disc 6 and is input into the top guide 3, so that it prevents the supplying yarn from being cut and it can also increase the efficiency of doubling yarns.
  • the fly disc 4 is rotated continuously by the tension of the yarn input into the top guide 3 from the bobbin 1.
  • the yarn input into the top guide 3 by the rotation of the disc hole 12 is twisted evenly by the rotation of the rotary disc 10 while passing the yarn guiding pipe 26, without an additional adjustment of yarn tension.
  • the doubled yarn comprising both rubber yarn and spun yarn such as cotton yarn or filament yarn is twisted to have many tangles in the yarn-twisting zone, it is possible to get a covering yarn since the rubber yarn is located in the center and the spun yarn or the polyester filament yarn is formed on the surface and twisted evenly.
  • the doubled yarn which is twisted in the yarn guiding pipe 26, is twisted evenly by the rotation of the rotary disc 10, comes out of the yarn guiding pipe 26 through the eyelet 8, and is wound in the conventional cylinder through the snail wire 11.
  • Ballooning occurs between the eyelet 8 and snail wire 11 and the quality of the doubled yarn is controlled according to the size of the ballooning.
  • the yarn-twisting zone and this part the detailed description will be omitted since they are the same as the zone of the conventional two for one twister.
  • the size of ballooning is designed to be controlled at a user's discretion by controlling the position of the snail wire 11 up and down.
  • this invention has an advantage in that even twisted yarn can be made without using an additional tension adjustment apparatus for yarn since doubled yarn, both threads of which have the same yarn tension is guided into the yarn-twisting zone.
  • this invention at a conventional two for one twister, by installing a fly disc 4 which is rotated on the top of the tenser 5 and inputting the supplying yarn 2 into the top guide 3 by the disc hole 12 which is rotated circumferentially having the same diameter as or larger diameter than that of a tenser disc 6 or the maximum diameter of winding layer wound on the bobbin, it is possible to improve the unwinding characteristics of yarn and to prevent the supplying yarn from being cut. Also, with only simple conversion said above, it is possible to achieve high speed doubling and twisting operations as well as to manufacture the covering yarn easily.
