摘要:
A weft traveling condition detection apparatus in an air jet loom detects a traveling condition of a weft yarn that is inserted through a weft passage by air injection of a main nozzle and a sub-nozzle. The apparatus includes a balloon sensor, and a first weft sensor, and a comparison processer determining a time difference. The apparatus includes a first memory storing data of values representing the time difference relative to an injection pressure of the sub-nozzle, a second weft sensor, and an averaging processor averaging an integrated voltage for different injection pressure of the sub-nozzle to determine the average of the integral value, a second memory storing data of values representing the average of integral value relative to the injection pressure, and a display on which the data of values stored in the first and second memories are indicated in one chart.

L'invention consiste à conférer au mors mobile (8), prévu strié, une orientation oblique par suite du positionnement de son arbre (7) par rapport au mors fixe (6 a ), de façon à engendrer un effet d'auto-serrage sur le brin du fil (17) qui vient d'être insèré dans le pas, et à permettre au contraire le glissement contrôlé du brin qui est resté solidaire de L'ergot (18) de la fausse navette (14).
