    • A warp insertion monitoring method and apparatus for positively protecting woven cloth from defects due to warp insertion error or failure. A warp detector is disposed on a loom so as to have a warp presence/absence detection region located at a front or rear side and in the vicinity of a reed which serves for beating a weft inserted through a shedding formed by the upward/downward motion of healed frames against a cloth fell. The presence or absence of abnormalities in respect to the positions at which warps are inserted through the reed is identified on the basis of detection information available from the output of the warp detector. Detection timing for the warp detection information is so established as to fall within a period during which the loom is stopped, so that the presence or absence of errors in respect to the warp insertion can be detected before the loom is restarted.
    • 一种经纱插入监测方法和装置,用于由于经纱插入错误或故障而积极地保护织布免受缺陷。 弯曲检测器设置在织机上,以便具有位于前后侧和在筘附近的经纱存在/不存在检测区域,该筘片用于通过由向上/向下运动形成的脱落插入的纬纱打纬 治疗框架对着布下落。 基于从翘曲检测器的输出可获得的检测信息,识别出通过舌簧插入经纱的位置的异常存在或不存在。 弯曲检测信息的检测定时被建立为落在织机停止的时间段内,从而可以在织机重启之前检测是否存在相对于经纱插入的错误。

    • An apparatus for inserting a weft into a shed by jetting fluids in a jet loom comprises a plurality of thin plate-like members arranged in alignment in the direction of weft insertion on a sley, each of the thin plate-like members being provided with an opening in the same position of each of said thin plate-like members to form a guiding channel, and nozzle means for jetting fluids through the guiding channel. Each of the thin plate-like members is provided with at least one cavity which is formed adjacent the circumference of each of the openings of the thin plate-like members on a downstream sidewall, in the direction of weft insertion, of the mutually facing sidewalls thereof. Due to the formation of the aforesaid cavity, the amount of the fluid flow escaping through the space between each two adjacent thin plate-like members outside of the guiding channel without narrowing the width of the space therebetween. As a result, the flight of the weft is remarkably stabilized and the flying speed of the weft is increased with reducing the consumption of fluids jetted from nozzle means.
    • 一种用于通过在喷气织机中喷射流体将纬纱插入梭口的装置包括沿着纬纱插入方向排列成排列成多个薄板状构件,每个薄板状构件设置有 在每个所述薄板状构件的相同位置处开口以形成引导通道,以及用于通过引导通道喷射流体的喷嘴装置。 每个薄板状构件设置有至少一个空腔,所述至少一个空腔在相互面对的侧壁的沿纬线插入方向的下游侧壁上邻近薄板状构件的每个开口的圆周形成 其中。 由于形成上述空腔,流体流量在引导通道外部通过两个相邻的薄板状构件之间的空间逸出,而不会缩小其间的空间宽度。 结果,纬纱的飞行非常稳定,纬纱的飞行速度随着喷嘴装置喷射的流体的消耗减少而增加。
