eng.weaving-production-rate Calculator
Calculates loom weaving production rate (metres/day) from loom speed, reed count, and efficiency factor. Weaving production rate = picks/min × 60 × efficiency / (picks/cm × 100) — modern rapier looms achieve 800–1,000 picks/minute vs. 200–400 for shuttle looms.
Inputs
Loom Speed Rpm
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Reed Width Cm
Horizontal extent perpendicular to the length.
Efficiency Pct
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Ends Per Cm
Reference formula or conversion factor shown for context.
Results
fabric production (m/min)
The result of multiplying all input values together.
fabric area production (m²/hr)
The result of multiplying all input values together.
total warp ends
The combined total across all inputs and components.
daily output (8-hr shift, m²)
Reference formula or conversion factor shown for context.
production = (speed × efficiency) / 100
Useful output divided by total input, as a percentage. True 100% efficiency is impossible — losses appear as heat. LEDs: 30–50%. Electric motors: 85–97%. Switching supplies: 85–95%.
