（産業上の利用分野）
本発明は織布工程における経糸準備段階で使用するのに
適した綜絖への糸通し装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a heald threading device suitable for use in a warp preparation stage in a weaving process.
（従来の技術）
織布工程で自動化の最も遅れているのは綜絖通し工程で
あり、多品種少量生産の最大のネックとなっている。(Conventional technology) The heddle threading process is the least automated weaving process, and is the biggest bottleneck in high-mix, low-volume production.
現在実用化されている綜絖通し装置は極めて高価であっ

品種切り替えを必要とする毛織においては品種切り替え
時間の短縮、人的コストの低減上最大の問題であった。The heald threading devices currently in practical use are extremely expensive, and very few of them are actually in use. Moreover,
Since the thread is passed through a needle through the eye hole of the heddle, it has the disadvantage that the heddle is easily damaged. For this reason, threading the heddles has been forced to be done manually, and this has been the biggest problem in shortening the time for changing types and reducing human costs in woolen textiles, which require frequent changes in types.

のために移動される。(Operation) First, set the thread guide groove on the nozzle body example and the thread guide groove on the nozzle cover side so that they are offset. The heald is moved and placed on the threading device set in this way using a known moving means, and the two air jet holes and the eye hole of the heald are positioned in close opposition to each other. Next, when a compressed air source is connected to the nozzle body and air is injected from both of the air jet holes, the tip of the yarn is sucked along the yarn guide groove of the nozzle body, and the tip of the yarn is sucked along with the compressed air from both of the air jet holes. Air is ejected from the air outlet toward the eye hole of the heald. The diameter of the air outlet in the nozzle cover is sufficiently small compared to the huge diameter of the heald, and the air outlet and the heald are close enough to each other, so the ejected thread can easily pass through the eye hole of the heald. . Next, the step is to release the thread from the device. While the supply of compressed air to the nozzle body is stopped, the nozzle body and the nozzle cover are relatively rotated by the operation of the nozzle cover opening/closing mechanism, so that the two yarn guide grooves are brought into correspondence with each other. In this state, when compressed air is supplied to the yarn discharge air outlet, the yarn is discharged to the outside from both yarn guide grooves. After the yarn is released, the two yarn guide grooves are rotated and shifted by the nozzle cover opening/closing mechanism, and the heald is moved for the next threading.
