Air-Jet Loom Speed and Machine Width Optimisation
topic
Air-jet loom speeds of 900 to 1500 picks per minute are achieved on standard widths of 1.9 to 2.8 metres with modern servo-beat-up systems, with maximum speed limited by the time available for weft insertion within the open shed period that decreases as machine speed increases, while wide-width machines above 3.5 metres require proportionally higher relay nozzle air pressure to maintain adequate weft velocity across greater insertion distance.
Role
Optimises the production rate per loom investment by selecting machine speed and width combinations that maximise metres of fabric production per hour within the limits imposed by weft yarn type, fabric construction, and compressed air system capacity, with speed-width trade-off analysis for each product determining the optimal machine specification that balances production rate against insertion reliability and air consumption.
