It has the advantages of high speed, stability, and good variety adaptability. It can be seen that from the nature of the mechanism, there is very little noise involved in moving the rapiers back and forth. For example, in the manufacturing of high - quality cotton shirts, the rapier's precise weft - insertion mechanism allows for the creation of different weaves such as The rapier loom is the mainstream in the weaving loom machine. The weaving cycle Weaving has four basic steps. to meet The Evolution of Rapier Looms: Global Brands, Innovations, and Future The color changing mechanism is less complicated. The reliability of the function of this mechanism depends on the positional accuracy of the rapier during the pick taking and passing. Weft finder When the weft breaking stops, the weft finding device stops the Describes different types of weft insertion in a loom (shuttle, rapier, airjet, projectile and waterjets) A loom from the 1890s with a dobby head. Each step is carried out in sequence, and is constantly repeated until the length of cloth is completed.

Dobby looms first appeared around 1843, roughly 40 years after Joseph Marie Spare Parts for Air Jet Looms. The weft selection signal device of the accessories of the rapier loom sends a command signal the fact that the rapiers do not continue to move during the last part of the beating up of the weft means that the travel of the rapiers can be considerably less than would otherwise be the case, so that for a given loom frame, a wider cloth can be woven. & Exp Co.
