The stop warp strips in the textile industry have the following characteristics:
1. Exquisite structural design:
Groove design: There are multiple grooves distributed along the length direction at intervals on the upper edge of the stop bar body. The function of these grooves is to receive the stop warp pieces that fall directly above. When the warp yarn breaks, the stop warp pieces will lose the support of the warp yarn and naturally fall onto the stop warp strips. The grooves can ensure that the stop warp pieces are correctly placed in the predetermined position, so as to trigger the stop signal in a timely manner and avoid the situation of undetected broken warp defects.
Insulation structure: In order to ensure the normal operation of the circuit and the correct transmission of signals, insulation layers are usually installed inside the stop bar to separate different conductive parts. For example, some warp stopping strips have an insulation layer between the conductive rack and the groove wall, which can prevent current from conducting in unnecessary places and ensure that the conductive contact between the warp stopping strip and the warp stopping plate is correct and effective.
Special connection structure: Some warp stopping strips may have special connection structures to provide a stable connection with warp stopping frames or other textile equipment components. For example, some warp stopping strips are fixed to the warp stopping frame through specific slots, screws, etc., to ensure that they will not loosen or shift during the textile process.
2. Excellent material properties:
Good conductivity: The stop warp strip needs to have good conductivity because its working principle is to trigger an electrical signal through the contact between the stop warp piece and the conductive part on the stop warp strip, thereby controlling the automatic stop of the weaving machine. So, the material used to make stop warp strips is usually a metal or alloy with good conductivity, such as copper.
Strong wear resistance: During the textile process, the warp stopper will constantly rub against the warp stopper, and prolonged friction will cause wear on the warp stopper. Therefore, the material of the warp stop strip needs to have high wear resistance to ensure its service life. For example, alloy steel materials that have undergone special treatment can improve the wear resistance of the warp bar, reduce downtime failures and equipment replacement frequency caused by wear.
3. High dimensional accuracy:
Correct length: The length of the warp stop strip needs to match the size of the textile equipment to ensure that it can cover the entire warp yarn area and correctly detect the condition of each warp yarn. If the length of the warp stop strip is insufficient, there may be missed warp yarn detection; If the length is too long, it may affect the normal operation or installation of textile equipment.
Uniform width and thickness: The width and thickness of the stop bar need to be kept uniform to ensure smooth movement of the stop plate on the stop bar, without any jamming or skewing. A uniform width and thickness also help ensure good contact between the warp stop piece and the warp stop strip, improving the accuracy of warp break detection.
4. Closely cooperate with the amenorrhea film:
Shape adaptation: The shape of the stop strip is usually adapted to the stop strip to ensure that the stop strip can be stably hung on the stop strip. For example, the cross-sectional shape of some stop strips may be circular, square, or other special shapes to meet the installation requirements of different types of stop strips.
Appropriate spacing: The spacing between the warp stopping strips needs to be set correctly according to the density of the warp yarn and the requirements of the textile process. Excessive spacing may result in delayed detection of warp yarns, while insufficient spacing may affect the normal movement of warp yarns and even lead to warp yarn breakage.
