The biggest advantage of the weft insertion system of
the rigid rapier loom is to actively transfer the weft to the center of the weaving mouth without any guiding device. The
rigid rapier loom covers a large area, mainly because the reed width has a certain limit.
The weft insertion system of
flexible rapier loom has strong adaptability, wide application range, significantly increased weft insertion rate, and the reed width is 460cm.
In the last 15 years of the 20th century, the electronic computer was introduced into
the loom, and the microelectronic CAD-CAM system was widely used, which formed a perfect combination of microelectronic technology, information transmission technology and weaving technology. The combination of many electronic devices and systems with the loom became an integral part of the rapier loom, especially the wide application of microelectronic technology in
the rapier loom, including weft insertion technology. Some weft insertion elements have been greatly improved, with small volume and light weight.
Due to the wide application of microelectronic technology, the speed and weft insertion rate of rapier loom are greatly improved. In various weft insertion modes, such as shuttle weft insertion, rapier weft insertion, air jet weft insertion and water jet weft insertion system, the weft insertion speed of rapier is also very high in addition to air jet weft insertion. In the last 50 years of the 20th century, rapier looms have made remarkable progress, especially showing the world the latest high-tech rapier looms at Milan in 1995 and Paris in 1999.
