針ヘルドであった。2. Description of the Related Art A heald for transmitting an opening motion to a warp yarn has a heald bar fixed to a heald frame, and a large number of mails are implanted in the heald bar. As the mail, a needle-shaped sewing machine having a needle-shaped hole is usually used. However, in the case of a thick yarn, if the hole is directed to the front, the hole becomes large and the needle interval of mail becomes coarse, so that a dense fabric cannot be formed. If the needle tip is flattened and widened in order to enlarge the hole, the distance between the needles cannot be further increased. The present applicant has started development of a four-axis fabric and a four-axis loom for more than ten years, and has made many proposals for a weaving structure and each member of the loom. For example, JP-A-63-92751, JP-A-01-292140, JP-A-02-2002
No. 6649, JP-A-02-160947, JP-A-04-91255, JP-A-08-134738, JP-A-08-134747 and the like. However, all of these warp thread healds were the needle healds of the mail described above.

転以上は出し難いものであった。Therefore, if the hole of the needle heald is arranged obliquely from the direction perpendicular to the direction of the heald bar or in the same direction in order to increase the space between the needles, the space between the needles is widened. Since the slack yarn enters in addition to the weft yarn, the slack yarn is caught at the swollen portion around the hole, and it becomes difficult to form an opening for inserting the weft yarn, thereby causing the fabric to be misaligned. For this reason, it was difficult for the weaving speed of the four-axis loom to exceed 60 rotations.

It is an object of the present invention to solve the drawbacks and to develop a warp yarn heald for a loom which can efficiently perform a shedding operation by increasing the weaving speed of a dense fabric.

い。通常3〜6mmφのステンレスパイプを用いる。That is, the gist of the construction of a warp yarn heddle for a loom adopted in the present invention is that a number of warp yarns are arranged at equal intervals within the weaving width of the loom and the weft insertion opening is provided. A warp yarn heald for a loom, characterized in that a number of pipes are arranged and attached to a heald bar. It is preferable to change the thickness of the pipe in accordance with the thickness of the yarn. However, as long as the warp yarn passes, an appropriate number of healds may be used in relation to the weaving density. Usually, a stainless steel pipe of 3 to 6 mmφ is used.

Since the yarn is deformed according to the shape of the pipe, the yarn is formed into an elliptical shape by flattening it to some extent from a perfect circle in order to increase the interval between the pipes. The elliptical shape is preferably a pipe having an outer diameter of 5 mmφ and a flat portion of about 3 mm. Since the warp yarn is pulled in the reed direction of the fabric, it is preferable that the tip of the pipe be curved to reduce the resistance. The degree of curvature is preferably about 10R to 30R. In addition to chamfering, use a ceramic material or other hard material coating to increase the abrasion resistance of the tip, or use a hard material of the pipe itself. .

プ間隔7は4.35mmの隙間が確保できることになる。As is apparent from these figures, a large number of pipes 2 are arranged in a row with respect to a heald bar 1 and are planted. In this case, the heald bar 1 is made of an aluminum alloy and has a large number of holes 3 into which the pipes 2 are planted. In this embodiment, the thickness is 25 mm, the vertical width is 50 mm, and the length is 1320 mm. This length is obtained by adding the mounting portions 4 on both sides, and the actual length is 1280 mm.
The pipes 2 are arranged as close as possible to this substantial length of 1280 mm. For example, when the pipes 2 are 5 mmφ, 200 pipes can be mounted by planting 1.35 mm between the pipes. Therefore, since there are two heald frames before and after,
Zero warp yarn enters the weave width of about 1200mm. And, even if the pipe installation interval 5 is 1.35 mm, if the 5 mmφ pipe 2 is formed into, for example, a flat portion 6 having a short diameter of 3 mmφ, the pipe interval 7 can secure a gap of 4.35 mm.

12,000dtの糸の太さは約4mmである。When a stainless steel pipe having an outer diameter of 5 mmφ and a thickness of 0.5 mm is used, the inner diameter of the pipe 2 becomes 4 mmφ, but it is possible to use up to 12,000 dt yarn with 2,000 dt 2 × 3 strands.
The thickness of the 12,000 dt yarn is about 4 mm.

2〜3倍に高めることができる。As described above, when the pipe 2 is formed as a pipe heald and has the flat portion 6, the opening of the warp yarn becomes extremely stable and the pipe interval 7 can be sufficiently obtained. Weaving slack yarns and weft yarns are no longer caught on healds. The weaving speed can also be increased at least two to three times the conventional one.

類によっては必ずしも湾曲にする必要はない。The tip of the pipe 2 is bent to 20R to form a curved portion 8.
, Because the warp yarn coming out of the tip comes out in the weaving direction,
Since the pulling direction coincides with the pulling direction of the reed and can be pulled out stably, the deformation of the flat pipe portion 6 and the abrasion of the tip of the curved pipe portion 8 are small, and the durability is improved. In order to reduce tip wear, it is more preferable to simultaneously form a coating layer on the curved portion 8 by ceramic spraying and to chamfer the processed end. It is effective to simply cut the end obliquely with a straight pipe and chamfer the end, so that it is not always necessary to make it curved depending on the type of warp yarn.
