The ISO 1865 standard, published by the International Organization for Standardization (ISO), includes definitions for installations of serrated rods for mechanical warp stop motions with the support of figures and descriptions. This standard also includes values for the cross-section dimensions of combined serrated bars.

Serrated rods for mechanical warp stop motions are relevant for looms. These bars provide a mechanical harness stopping action for looms. The purpose of this equipment is to provide a warp stop device that is simple to construct, easily adjustable and easily monitored.
Another purpose of this system is to provide a mechanical warp stop motion, in which the power or knurled wires can be moved along the serrated bars so that the bundle can be hung comfortably and new strength can be easily added to the harness. A mechanical harness warp stop is provided, comprising a pair of serrated rods that perform a common up and down motion while the power of the harness moves back and forth in the same direction.
The warp stop motion is an auxiliary loom motion. The main purpose of the warp stop motion is to stop the loom immediately when an end break occurs during the operation of the loom. The warp stop motion plays an important role in improving the quality of the fabric and the efficiency of the loom. If an end break occurs and the loom continues to run, a thread build-up will occur, causing multiple end breakages. Thus, the efficiency of the loom decreases, if the loom continues to work, the fabric becomes defective and the quality of the fabric decreases. The warp stop motion helps to increase the efficiency and improve the quality of the fabric woven on the loom.
Generally, there are three types of warp break stop motion: mechanical warp break stop motion, electric warp break stop motion and electronic warp break stop motion.
Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, within the scope of ISO 1865 standard, textile machinery and accessories, serrated rods for mechanical warp stop movements, indications of dimensions and It also provides testing services for cross-section dimensions.
