The invention of claim 4 relates to item 2 or 3 of the claim. In the yarn guide area of the rod-shaped yarn guide, looking at the center axis of the yarn winding surface, the length of the weft yarn is measured. The weft yarn path between the delivery position and the winding start position of the yarn winding surface is closer to the yarn guide area as it advances from the feed position side to the winding start position side, and then it is moved away from the yarn guide area so as to The weft path is skewed. The contact length of the weft yarn in the yarn guide area becomes longer. The invention of claim 5 is any one of claims 1 to 4, the rod-shaped yarn contact portion is provided with a core material, and a sliding piece installed on the core material, and the weft yarn is made in contact with the Slide the tab to be guided. 517112 V. Description of the invention (4) The material suitable for the sliding guide on the weft can only be used for the sliding contact piece. If the sliding contact piece is detachably attached to the core material, only the sliding contact piece needs to be replaced. The invention of claim 6 is based on claim 5, the core material is a rod-shaped rod, and the sliding piece is formed into a shape of a cut-out cylinder that can be inserted from the surface of the core rod. Therefore, the sliding piece is easy to install on the mandrel. The invention of claim 7 is based on claim 6 of the present invention, and the step between the mandrel and the sliding piece is covered by the management. The pipe system is used to prevent the weft yarn from being caught by the difference between the center rod and the sliding piece.

[Embodiment of the invention] Hereinafter, a first embodiment of the present invention, which is embodied, will be described with reference to Figs. 1 to 3. As shown in Fig. (A), the storage drum Π system as the yarn winding portion is supported by the rotation shaft 12. The storage drum 11 that rotates integrally with the rotation shaft 12 is formed of a large diameter portion formed as the yarn winding surface 1 Π and a small diameter portion formed as the air flow path forming peripheral surface Π 2. Yarn winding surface 1 1 1 is pushed by! 1 3 and the circumferential surface Π 4 are prepared. Equipped with a ring cover 丨 3 on the storage drum;!! Perimeter. The annular airflow path L is formed between the annular cover 13 and the airflow path forming peripheral surface Π2. As shown in FIG. 2 (a), the air duct 14 is connected to the annular cover π. The air supply pipes 1 and 4 are connected to the tangential direction to the annular air flow path L. The air supply pipe 14 is connected to the blower 15 and blows the air flow sent from the blower 15 into the annular air flow path L. Above the storage drum 11 is rotatably provided with a delivery roller. 6. Description of the invention (6) The exit roller 16 is crimped with a yarn pressing roller 17. The delivery roller 16 and the pressing roller 17 constitute a weft length measuring section 23. The weft Y 'supplied from the weft bobbin yarn 18 is passed through the yarn guide 19 through the pressure-contact portion between the feed roller 16 and the press roller 17. The weft yarn Y between the feed roller 16 and the press roller 17 is supplied to the storage drum Π side at a predetermined rotation speed of the feed roller 16. A yarn guide 24 is arranged between the weft length measuring section 23 and the storage drum 11. As shown in Figs. 3 (a) and 3 (b), the yarn guide 24 is a tube formed by bending a mandrel 25, a slide piece 26 fixed to the mandrel 25, a tube covering the mandrel 25 and the slide piece 26 with steps 241 and 242. 27, 28. The core rod 25 as the core material is made of iron, and the sliding contact piece 26 is made of ceramic. The tubes 27 and 28 are made of heat-shrinkable resin. As shown in Fig. 1 (a), the sliding contact piece 26 has a U-shaped cross section, and has a cutting cylinder shape that is close to a semi-linear cylindrical shape. The surface of the sliding contact piece 26 is a convex peripheral surface 261 having no unevenness. The sliding contact piece 26 is, for example, a linearly-shaped central portion 25 1 adhered to the mandrel 25 by a thermosetting resin. The central portion 251 of the sliding contact piece 26 and the core rod 25 constitutes a rod-shaped yarn contact portion 243. As shown in FIG. 2 (a), both ends of the mandrel 25 are fastened and fixed to the fixing portion 30 with bolts 29. As shown in Fig. 2 (b), the mandrel 25 crosses between the peripheral surfaces of the two rollers 16 and 17 and the yarn winding surface Π1. The sliding contact piece 26 is on a plane orthogonal to the center axis C of the endless yarn winding surface 1 Π. The sliding contact piece 26 is disposed directly above the push-pull 1 1 3 when viewed in a direction orthogonal to the central axis C. The sliding contact piece 26 is arranged obliquely to the common contact plane K of the circumferential surface of the feed roller 16 and the yarn winding surface 1 1 1 when viewed in the direction of the central axis C of the ring-shaped yarn winding surface Π 1. That is, the convex peripheral surface 26 1 of the yarn guide region is viewed in the direction of the central axis C, and the sending position 23 1 of the weft yarn length measuring portion 23 and the yarn 517112 are described in the fifth aspect of the invention. (7) Winding surface π 1 The weft path between positions Π 5 is advanced from the sending position 2 3 1 side to the winding start position 1 1 5 side, and is closer to the convex peripheral surface 26 1, and then the weft path is made from the convex peripheral surface 26 1 to leave. Skewers. The weft Y sent from the weft length measuring section 23 is guided by the convex peripheral surface 261 contacting the sliding contact piece 26 directly above the push 1 1 3. That is, the starting position of the weft sending out of the weft measuring section 23, that is, the joining position between the rollers 16 and 17, and the winding starting position 1 1 5 on the yarn winding surface 1 1 1 and the sliding contact 26 The positional relationship between the disposition positions is a relationship that when the weft yarn γ is wound on the yarn winding surface Π 1, the weft yarn Y sent from the weft yarn length measuring portion 23 ′ often contacts the convex peripheral surface 26 1 of the sliding contact piece 26. The weft yarn Y guided by contacting the convex peripheral surface 261 of the sliding contact piece 26 is passed between the storage drum Π and the ring-shaped cover 13. The air flow blown in from the blower pipe 14 is rotated in the endless air flow path, and the weft Y crosses the endless air flow path. Therefore, the weft yarn Y is subjected to a swirling airflow in the annular airflow path L. When the weft clamp 21 is closed, the weft yarn Y sent between the roller 16 and the press roller 17 at a constant speed is applied on the rotating yarn winding surface 1Π by the rotating air current. It is wound by applying tension. When the weft inserter is opened while spraying with the nozzle 22, the weft yarn Y stored on the yarn winding surface 1 1 1 is unwound and pulled out. The unwinding weft yarn Y is pulled out from the yarn winding surface 1 1 1, and weft injection is performed from the weft insertion nozzle 22 through the yarn guide 20 and the weft clamp 2 1 in front of the storage drum 11. In the first embodiment, the following effects are obtained: (1 -1) The weft yarn Y sent from the weft yarn measuring section 23 often contacts the peripheral surface of the sliding piece 26, but the weft yarn Y sent from the weft yarn measuring section 23 has almost no Zhong-9- 517112 V.

The linear sliding piece 26 on the plane of the positive father on the center axis c plane is easy to be placed close to the push-out 1 1 without pushing the weft length measuring section 23 or the yarn winding surface 1 1 1 3 The largest diameter part side of 3. In this embodiment, the sliding piece 26 is a weft yarn γ sent from the weft length measuring portion 23, and is disposed on the side of the largest diameter portion that can often contact the convex peripheral surface 26 and is close to the push-out. Therefore, the weft yarn Y sent from the weft yarn measuring section 23 does not shake in the direction of the central axis C, and the winding yarns wound on the yarn winding surface 1 Π do not overlap with each other. As a result, no defective weft insertion caused by the overlapping of the windings on the yarn winding surface 111 occurs. (1-2) The operation for smoothing the inner surface of the light ring body is easier than the operation for smoothing the outer surface of the light ring body. Therefore, it is easier to smooth the convex peripheral surface 26 1 of the lightly sliding contact piece 26 than the inner peripheral surface of the conventional ring-shaped yarn guide. This can improve the ease of operation ', which leads to a reduction in the cost of the yarn guide. (1-3) The convex peripheral surface 26 1 of the cylindrically divided cylinder-shaped sliding contact piece 26 having a shape close to two halves is a shape which is advantageous in terms of smooth smooth light. (1-4) The weft yarn measuring section 23 at the time when the weft yarn Y is wound on the yarn winding surface 1 and the yarn winding surface 1 1 1 is on the common contact plane as shown in FIG. 2 (b) K on. The weft yarn Y in contact with the convex peripheral surface 26 1 of the yarn guide region of the yarn guide 24 is in a straight line or a slightly curved line shape in the common contact plane K -10- 517112 V. Description of the invention (9) to the yarn winding surface π 1. The greater the contact resistance between the weft yarn γ and the sliding piece 26, the greater the possibility of damage to the weft yarn Y. The weft yarn Y contacting the convex peripheral surface 261 of the sliding contact piece 26 in a straight line or a slightly curved line shape has a small contact resistance with the sliding contact piece 26. Therefore, the contact resistance between the weft yarn Y and the sliding contact piece 26 is very small, and damage to the weft yarn Y in contact with the yarn guide 24 is prevented. (1 -5) The weft yarn wound and stored on the yarn winding surface 1 1 1 is ejected by the weft insertion nozzle 22, and all the weft yarn Y sent from the weft yarn measuring section 23 is drawn out, which is attached to the yarn guide 24. The ground is bent and pulled to the side of the nozzle 22 for direct weft insertion. When the weft yarn Y is directly pulled from the yarn guide 24 to the weft insertion nozzle 22, the flight of the weft yarn in the warp opening is called restricted flight. In the restricted flight, it is also desired to slide the weft yarn Y to the yarn guide 24. The length of the often sliding contact piece 26 needs to be able to contact the length of the weft yarn Y. The structure in which the sliding contact piece 26 is arranged in parallel to the plane where the center axis C of the yarn winding surface 1 1 1 is orthogonal is the length of the sliding contact piece 26 of the convex peripheral surface 26 1 with the yarn guide region as the shortest required Advantages in length. The shortening of the sliding contact pieces 26 helps to reduce the cost of the yarn guide 24. (Bu 6) The longer the contact length of the weft Y on the convex peripheral surface 261 is, the smaller the surface pressure on the weft Y with the contact between the convex peripheral surface 26 1 and the weft Y becomes, and it is difficult to produce a sliding contact with the sliding piece 26 Damage to the weft Y. The sliding piece 2 6 is viewed in the direction of the central axis C of the looped yarn winding surface 1 1 1. The feeding position 23 1 of the weft yarn length measuring portion 23 and the yarn winding surface 1 丨 start the winding start position 11. The weft path between 5 is skewed. With respect to a configuration in which the weaving yarn path obliquely crosses the sliding contact piece 26, when the system yarn is wound on the yarn winding surface 1 π, the convex circumferential surface 26 1 can increase the contact length of the weft yarn γ. -11- V. Description of the invention (] 〇) (1-7) The structure in which the sliding contact piece 26 is mounted on the mandrel 25 is also suitable for sliding contacting the guide weft Y. The material is only used for the sliding contact piece 26 . If the material suitable for sliding the weft insertion yarn Y is expensive, the mandrel 25 can be a low-cost material (for example, iron), and the cost of the yarn guide 24 can be avoided. U-8) For example, when chromium plating is applied to the convex peripheral surface of an iron sliding contact piece, the sliding contact between the convex peripheral surface and the weft Y is worn relatively early. Although the sliding contact piece 26 is adhered to the mandrel 25 with a thermosetting resin, the sliding contact piece 26 can be detached from the mandrel 25. The detachable structure may be replaced with only the sliding contact piece 26 if necessary. (1-9) The sliding contact piece 26 in the shape of a cylinder can be easily fitted by inserting the center rod 25 from the side. (1-10) When the loom is in a stopped state, the weft yarn between the weft length measuring section 23 and the storage drum 11 relaxes gently, and the weft yarn is tensioned when the loom is operated when it is turned on. When the step difference 241, 242 between the core rod 25 and the sliding contact piece 26 is exposed, the relaxed weft yarn may be caught on the step difference 24 1, 242 during tensioning. The steps 241 and 242 are covered by the tubes 27 and 28. The tubes 27 and 28 prevent the weft yarn Y from hanging on the steps 24 and 242. (1-Π) The covered sections 241 and 242 are covered by the tubes 27 and 28, which are compared with the sections 24 and 242. The heat-shrinkable resin tube having a larger inner diameter is fitted to the sections 241 and 242 and is contracted by heating. The tube comes into close contact with the mandrel 25 and the sliding piece 26. Therefore, the tubes 27 and 28 can be tightly connected to the mandrel 25 and the sliding contact piece 26 without holding the weft yarn Y. The heat-shrinkable resin tubes 27 and 28 are superior to the core rod 25 and the sliding contact piece 26 and are easily covered by the difference 241 and 242. (1 -1 2) The core rod 25 is easy to bend and can be set so as not to interfere with the storage drum. -12- 5 'Description of the Invention (n) 11, Weft yarn length measuring portion 23 and the like.

The central portion 251B of the core rod 25B and the sliding contact piece 26B constitute a curved rod-shaped yarn contact portion 243B. When the weft yarn Y is wound on the yarn winding surface 1 1 1, the sliding contact piece 2 6 B sent from the weft length measuring section 23 is slidably contacted to the sliding contact piece 2 6 B at the side end. In the restricted flight of the weft yarn, the weft yarn γ sent from the / fe yarn measuring length 2 3 is slid on the curved bottom of the sliding contact piece 2 6 B. During the restricted flight of the weft yarn, the weft yarn Y is slidably connected to the curved bottom of the sliding piece 268, which is effective in reducing the sliding resistance between the weft yarn γ and the sliding piece 26B during the weft restricted flight.
