The Middle Yarn Dividing Frame for Warp Stop Spacer Seat(often referred to as the stop warp piece divider/yarn divider) is the core positioning and separating component of the loom stop warp device. Its core function is to accurately separate, position, and stabilize the stop warp piece and warp yarn, ensuring reliable self stopping of broken warp, smooth yarn operation, and efficient and stable weaving.

1、 Core role (by functional priority)

1. Accurately separate the stop plates to prevent twisting and accidental stopping

       Separate multiple columns/layers of stop plates evenly according to the process spacing to form independent channels, avoiding collisions, stacking, and twisting of stop plates.

       To prevent the occurrence of non-stop, wrong parking, and stuck menstrual strips caused by overcrowding, and to ensure 100% reliability of menstrual strip testing.

2. Position and support the warp yarn, stabilize the yarn path

       Provide fixed and equidistant threading channels for warp yarns, ensuring that they are parallel, neat, and without crossing in the warp stopping area.

       Cooperate with the stop pad seat to fix the upper, lower, left, and right positions of the warp stopping piece, eliminating jumping and deviation during high-speed weaving.

3. Stabilize tension, reduce yarn wear and breakage

       Control the uniformity of tension in the warp stopping area to avoid yarn fuzzing and breakage caused by local tension mutations.

       Reduce the friction between the warp yarn and the warp stopper, as well as the yarn guide, and extend the lifespan of the yarn and warp stopper.

4. Adapt to high-density/wide weaving to enhance equipment stability

       Wide width and high warp density fabrics (such as home textiles and industrial fabrics) require a large number of warp stopping pieces. The grid frame can disperse the load, prevent deformation of the warp stopping pieces, and avoid disorder in the spacing between warp stopping pieces caused by bending of the frame.

       Multi column grid (such as 6 columns, 8 columns) is compatible with high-speed shuttleless looms (jet/rapier/spray) to meet efficient production requirements.

5. Easy to wear and maintain

       Comb tooth/groove type structure simplifies the threading operation and improves the efficiency of the blocking worker.

       Modular design facilitates cleaning, replacement of stop plates, and maintenance, reducing maintenance costs.

2、 Working principle and structural key points

       Structure: mostly made of metal/high-strength engineering plastic, with comb teeth, slot holes or positioning strips, installed between the stop frame crossbeam and the stop pad seat.

       Principle: By using comb teeth/grooves to physically isolate and position the warp stopping piece from the warp yarn, each warp yarn corresponds to an independent stopping piece. When the yarn breaks, the stopping piece accurately falls to trigger a stop without interference.

3、 Summary of Key Values

       It is the "order guarantee component" of the warp break self stop system, which directly determines the reliability of warp break detection, yarn operation stability, and weaving efficiency of the loom. It is an essential core component for high count, high-density, wide width, and high-speed weaving scenarios.
