    摘要： A weft withdrawing device of an air jet loom includes a blow nozzle blowing a weft that is ejected from a weft insertion main nozzle and determined to be a weft insertion failure to guide the weft to a weft withdrawing passage, a weft introducing duct that is integrally swingable with a sley forward and backward, a weft withdrawing mechanism withdrawing the weft guided to the weft introducing duct, and a weft sensor optically detecting the weft. The weft withdrawing device of the air jet loom includes a weft guide member. The weft guide member includes a cloth fell side top portion and a let-off side top portion. The cloth fell side top portion is located above the weft withdrawing passage.

    摘要： A weft thread tension control device for use in bobbin carrying shuttles. These shuttles include a bobbin compartment which supports a weft thread carrying bobbin, a weft thread tensioning apparatus which tensions the weft thread during its passage out of the shuttle and shuttle eyes which guide the weft thread from said shuttle. The tension control device comprises a tension actuated apparatus which is operative to sever the weft thread along its path of movement from the bobbin through the shuttle eyes upon the development of excessive tension therein.

    摘要翻译： 一种纬纱张力控制装置，用于卷筒运送梭子。 这些梭子包括一个支承纬线承载筒管的纱管室，一个纬纱张紧装置，它在纬纱穿过梭子时使纬纱张紧，并将纬纱引导到梭子上。 张力控制装置包括张力致动装置，其可操作以在其中在其中产生过大的张力时沿着其穿过梭眼的梭芯沿其运动路线切断纬纱。

    摘要： In a loom of the type wherein the filling yarn is inserted into the warp shed in the form of cut lengths and wherein a reed serves for beating-up the inserted filling yarn into the fabric at the fell of the cloth, the combination therewith of improved means for severing the terminal ends of filling yarns projecting outwardly from at least one of the selvages of the fabric being woven; which improved means comprises positioning a cutter adjacent at least one end of the reed, and providing a relatively wide widthwise extending opening in the reed adjacent the end where the cutter is positioned, with the opening being of a width substantially greater than the dent spacing of the reed; so that when the reed is reciprocated in beating-up the filling yarn into the fabric, the cutter has portions thereof that are positioned in the opening in the reed for severing the terminal ends of the filling yarn close to the selvage of the fabric being woven.
