In the working process, when the warp yarn 2 is loosened or broken, the warp stop sheet 4 corresponding to the warp yarn 2 can automatically fall away from one end of the movable connection of the warp stop sheet 4 due to loss of the lifting force, and can automatically stop falling when the inner wall of the middle hole 5 is in contact with the induction wire 3 to form a power-on loop due to the limitation of the middle hole 5 in the falling process, so that the falling height of the warp stop sheet 4 can be controlled by adjusting the distance between the induction wire 3 and the inner wall of the middle hole 5 as required in practical application.
Therefore, the structural design of the invention can ensure that the warp stop sheet 4 falls onto the induction wires 3 in hundreds of percent, thereby effectively avoiding the problem of induction failure or delay caused by the fact that the warp stop sheet 4 falls into the empty space between the induction wires 3 in the prior art.

Specifically, the method comprises the following steps: the induction wire 3 is positioned in the middle hole 5, and the two sides of the induction wire approach to the inner wall of the middle hole 5, so that the falling path of the warp stop sheet 4 can be shortened, the warp stop sheet 4 is induced instantly by the section 2 of the warp yarn, the induction wire 3 is convenient to contact, and the reaction efficiency is further improved.
