    • The present invention has been conceived for the purpose of improving durability, reliability of a needle selection operation (reliability in warp shedding action), and load bearing capacity. In order to achieve this, at least a leading end aide 20a of each warp needle 2 is formed so as to be capable of bending by the contact with a corresponding warp-needle selection member 5 which has advanced into a path P of the warp needle 20, and an engaging member 17 is provided to be capable of engaging with a hook part 23 of the warp needle 20. According to this arrangement, by the contact with the warp-needle selector member 5, 35, at least the leading end side 20a, 50a of the warp needle 20, 50 is bent into engagement with the engaging member 17, 47. In this engaging state, when the transfer member 13, 43 is moved away from the warp-needle selector member 5, 35, the relative displacement between the warp needle 20, 50 and the transfer member 13, 43 is made. On the other hand, the warp needle 20, 50, which does not contact the warp-needle selector member 5, 35 and therefore ie not bent, is not brought into engagement with the engaging member 17, 47, and therefore it is moved away from the warp-needle selector member 6, 36 alone with the transfer member 13, 43. Thus, the relative displacement between the warp needle 20, 50 and the transfer member 13, 43 is not made. Either of these operations is made to corresponding warp needles 20, 50, thereby enabling warp shedding
    • 为了提高耐久性,选针操作的可靠性(经纱脱落动作的可靠性)和承载能力,构思了本发明。 为了达到这个目的,每根经针2的至少一个前端助手20a被形成为能够通过与已经推进到经针的路径P中的对应经纱选针构件5接触而弯曲 如图20所示,设置有能够与经纱针20的钩部23卡合的卡合部件17.根据该结构,通过与经纱选针部件5,35的接触,至少前端侧 经纱针20,50的弯曲部20a,50a弯曲成与接合部件17,47接合。在该接合状态下,当传递部件13,43从经纱选针部件5,3离开时, 经纱针20,50与传送构件13,43之间的位移被做出。 另一方面,不接触经针选择构件5,35并因此不弯曲的经针20,50不会与接合构件17,47接合,因此它被移开 从经纱选针元件6,36单独地与传递元件13,43接触。因此,经纱针20,50与传递元件13,43之间的相对位移没有形成。 对相应的经纱针20,50进行这些操作中的任何一个,由此实现经纱脱落
