Air jet looms use compressed air and nozzles to insert weft yarn into the shed of a weaving machine:
The shedding mechanism opens a gap between the two layers of warp sheet.
The major nozzle starts pumping air to move the yarn.
The relay nozzles along the reed channel move the yarn through the shed.
Here are some features of air jet looms:
Speed: Air jet looms can have a weft insertion rate of up to 2,500 meters per minute.
Nozzles: The main nozzle provides the initial acceleration, and the relay nozzles keep the yarn moving at a constant velocity.
Patterning: Air jet looms can use dobby and jacquard patterning technologies.
Yarn: Air jet looms can use a wider range of yarns than water jet looms.
Cost: Air jet looms are less expensive to buy, install, run, and maintain than other types of weaving machines.
