How does an Air Jet Loom work?

1.Warp Yarn Preparation: The process begins with the warp yarns, which are arranged parallel to each other on a beam. These yarns are then drawn through healds and reed, essential components for forming the shed and beating-up the weft yarn, respectively.

2.Shedding: Shedding is the process of raising and lowering the warp yarns to create a shed. In an Air Jet Loom, this is typically achieved using dobby or cam mechanisms that control the heald frames.

3.Weft Insertion: This is the key step that differentiates air jet looms from other types. A main nozzle, connected to a compressed air supply, shoots a jet of air to carry the weft yarn through the shed. Additional relay nozzles, spaced along the width of the loom, help to keep the weft yarn moving at high speed and ensure it reaches the opposite side of the loom.

4.Beating-Up: After the weft yarn is inserted, the reed moves forward to push (beat) the weft yarn into place against the previously woven fabric. This ensures the fabric is tightly and evenly woven.

5.Fabric Take-Up: Once the weft yarn is beaten into place, the newly formed fabric is wound onto a cloth beam, ready for further processing.

6.Warp Let-Off: Simultaneously, the warp beam releases more warp yarn at a controlled rate to maintain consistent tension and keep the weaving process continuous.
