Between 1963 and 1999, the speed of the rapier looms and the weft insertion rate at the International Textile Machinery Exhibition were greatly changed.
For example, the weft insertion rate of a flexible rapier loom increased from 315 m/min in 1963 to 2000 m/min in 1999; the rotational speed increased from 200 r/min in 1971 to 800 r/min in 1999.
The weft insertion rate of rigid rapier looms increased from 400m/min in 1963 to 1300m/min in 1999, and the rotational speed increased from 300r/min in 1971 to 650r/min in 1999.
The speeds of Somet, Zell, Picard, Wantus, Dornier and Tsudakoma have increased significantly, and the speed of domestic rapier looms has reached 504r/min.
Efforts to improve the production and running performance of weaving machines, improve weaving efficiency and product quality are the goals of machine manufacturers to participate in the world competition. The rapier loom not only has a great increase in speed and weft insertion rate, but also the width of the loom.
It has also increased rapidly. After years of efforts to improve, the speed and weft insertion rate of the rapier loom has greatly exceeded the projectile weaving machine, but the width cannot be compared with the projectile loom.
