Work out loom production rate instantly with clear inputs, formula shown and shareable results.
Loom output is picks per minute divided by picks per centimetre, giving centimetres of cloth per minute, scaled by loom efficiency. Fine weft density directly cuts output: doubling picks per centimetre halves metres per hour at the same loom speed, which is why dense fabrics cost more to weave.
Loom production
Fabric (m/h) = loom rpm / picks per cm x efficiency x 60 / 100
Warp and weft stops, beam and quill changes, style changes, and mechanical faults. Air-jet looms on smooth yarn reach 90-95%; difficult yarns or wide fabric pull it to 80% or below.
No — the standard comparison is weft insertion rate, loom speed times reed width. A wide loom at moderate rpm can out-produce a narrow fast one.
