  However, the above-described conventional invention effectively prevents the yarn feeding device from rotating during operation of the yarn feeding device, thereby preventing twisting, untwisting and yarn breakage of the braided yarn due to the rotation of the yarn feeding device. A spindle holder in a yarn feeding device for a torsion lace machine capable of braiding a good lace place, which is not sufficient to eliminate the entanglement between yarns traveling between the bobbin and the beating portion. . In particular, the yarn fed from the bobbin bobbin is fed from the bobbin bobbin in the spindle whose position is changed by the rotation of the spindle plate, and is driven by a knife in the thread winding unit to obtain a torsion race place. Elimination of entanglement between yarns when a yarn traveling between a bobbin and a hitting portion, for example, a yarn having a long bristle, is an important issue.

The present invention has been made in view of the above points, and the object of the present invention is to insert a yarn traveling between a bobbin bobbin and a hitting portion through a lightweight pipe to facilitate knitting to obtain a torsion race place, entanglement, etc. It is an object of the present invention to provide an accessory for use in a torsion race machine in which the occurrence of scratches caused by the above is reduced, the knitting efficiency is increased, the strength at both ends of the pipe is increased, and the both ends of the pipe are not damaged.

The accessory used for the torsion race machine according to the present invention is such that the threaded bobbin mounted on the spindle is run along the circumference by controlling the individual rotation of the rotor metal arranged in an annular shape, and the thread drawn from the bobbin is slanted. In an accessory used for a torsion lace machine that travels upward and is gathered in a striking part provided in the center of the ring and inserts or separates a knife between yarns to weave a torsion lace with a desired pattern, The thread running between the bobbin mounted on the spindle and the striking portion is inserted into the lightweight pipe in a loose-fit manner, and chips are formed of a material having high strength at both ends of the lightweight pipe.

The accessory used for the torsion race machine according to the present invention is such that in the lightweight pipe, the tip on the knife side is formed as small and light as possible, the tip on the spindle side is formed slightly larger than the tip on the knife side, and is heavy. It is formed.

  The tips attached to both ends of the lightweight pipe are formed in a detachable structure.

  The knife-side tip is a cylindrical body, and a flange is formed at an end, and a cylindrical portion other than the flange is mounted so as to be inserted inside the lightweight pipe.

(1) In order to keep the weight of the pipe light, only the both ends of the pipe are reinforced with tips made of high-strength material. As a result, the entanglement between the yarns running between the bobbin and the striking part is eliminated or greatly reduced. It was reduced.
(2) Although the tip on the knife side of the pipe was made as small and light as possible, the tip on the spindle side was made slightly larger and heavier than that, resulting in the center of gravity of the entire pipe being biased toward the spindle.
(3) Chips were made of high strength materials at both ends of the pipe and reinforced. The spindle side is heavier than the knife side. As a result, the pipe that covers the thread with the tension angle of the thread ascending is
A moment that faces the spindle is generated. Therefore, the pipe is subjected to complicated vibrations from the thread and slides down to the spindle side.
(4) Therefore, the frequency at which the end of the pipe is struck by the knife is reduced, and a small tip may be reinforced and lightened.
(5) If the center part of the pipe is damaged or bent due to entanglement, each chip can be removed and reused.
(6) By forming the knife-side tip into a lightweight cylindrical plug-in type with a flange,
There is no damage to the chip and it can be used for a long time, which greatly improves the torsion lace knitting work.

  1 is a torsion lace machine, 2 is a thread with long hair such as a mohair thread, a thread indicating a special thread, 3 is a cylindrical lightweight pipe that is loosely covered with the thread 2, and 4 is equipped with a bobbin 5 6 is a spindle plate, 7 is a disk on which a plurality of spindles 4 are arranged in parallel on the circumference, 8 is a knife for winding the yarn 2 fed from the bobbin bobbin 5 with a threading unit 9 Each is shown.

  The lightweight pipe 3 is made of a thermoplastic resin or other lightweight material so as not to apply a load to the yarn 2. Since the lightweight pipe 3 continues to be struck by the head of the spindle 4 and the back of the knife 8, a compressive load is applied in the axial direction. It is the yarn 2 itself that is knitting that supports the lightweight pipe 3. The tension applied to the yarn is about 90 g on average, and increasing the strength by increasing the thickness of the lightweight pipe 3 makes the lightweight pipe 3 itself heavier, and the yarn 2 sinks with the weight of the lightweight pipe 3 and cannot be knitted. . Therefore, it is one condition to keep the lightweight pipe 3 light.

The knitted yarn 2 is stretched at a tension angle of 13 to 15 ° from the head of the spindle 4 to the knife side. The vibration of the yarn 2 during knitting includes vibration due to movement of the spindle 4, vibration due to touching, rubbing, and repelling the knife 8, vibration due to a spring for applying tension to the yarn contained in the spindle 4, In particular, the movement of the spindle 4 is a complex combined vibration such as a vibration caused by the spring pulling the yarn 2 when moved from out to in, and a vibration caused when the yarn 2 is supplied from the bobbin bobbin 5 by the spindle 4. Yes. The complicated vibration rocks the lightweight pipe 3 that covers the yarn.

  10 indicates a tip on the spindle side, and 11 indicates a tip on the knife side. The tip 11 on the knife side is made as small and light as possible. The spindle-side tip 10 is formed slightly larger and heavier than the knife-side tip 11. Further, the inner diameter of the spindle-side chip 10 is gradually tapered outward to prevent the chip 10 from coming off. The spindle-side tip 10 and the knife-side tip 11 are formed in a detachable structure, and when damaged, either the spindle-side tip 10 or the knife-side tip 11 is replaced, or both damaged tips 10 are replaced. , 11 and the lightweight pipe 3 itself may not be replaced. FIG. 3 (c) shows another embodiment of the knife-side tip 11, and shows a case where it is formed into a lightweight cylindrical insertion type provided with a flange 12.
