The biggest advantage of the rigid rapier loom weft insertion system is that it actively transmits the weft yarn to the center of the weaving mouth without any guiding device. The rigid rapier loom covers a large area, mainly because the width of the web has a certain limit.
The flexible rapier loom weft insertion system has strong adaptability, wide application range, and the weft insertion rate is significantly increased, and the width of the weft is 460cm.
In the last 15 years of the 20th century, electronic computers were introduced into looms. The microelectronics CAD-CAM system was widely used, which made microelectronics technology, information transmission technology and weaving technology form a perfect combination. Many electronic devices and systems combined with looms became swords. The components of the loom, especially the wide application of microelectronics on rapier looms, including weft insertion technology. Some weft insertion elements are greatly improved, small in size and light in weight.
Due to the wide application of microelectronic technology, the speed and the weft insertion rate of the rapier loom are greatly improved. In various weft insertion modes, such as the gripper weft insertion, the rapier weft insertion, the jet weft insertion and the water jet weft insertion system, the rapier weft insertion speed is also high except for the jet weft insertion. In the last 50 years of the 20th century, the rapier looms made remarkable progress. At the 1995 Milan and 1999 Paris exhibitions, the latest high-tech rapier looms were presented to the world.
