Claims

[Scope of utility model registration request]

In a shedding device that moves a heald frame up and down by a crank mechanism driven in synchronization with the weaving timing to form a warp opening, 1. In order to make the opening amount of the warp threads for waste selvage smaller than the opening amount of other warp threads, the vertical length of the thread passing hole of the heddle through which the warp threads for waste selvage are inserted and supported is set to the upper and lower lengths of the thread passing holes of the healds for other warp threads. A warp shedding device for discarding selvedges in a fluid jet loom, characterized in that the warp shedding device is larger than the length.
