Calculating Electronic Card Setup Fees and Loom Hour Output Surcharges
Electronic card fees cover digital hook mapping while loom hour output surcharges adjust metre costs for reduced insertion speed and lower shed efficiency.
Warp Stop Motion Rate
Interruption Frequency
Operational rate of automatic loom stoppages caused by broken or slack warp threads per million picks woven defines weaving line efficiency and yarn performance under tension. Electrical or optical drop wires detect lost warp tension instantly and trigger loom braking mechanisms. Production monitoring logs record warp stop motion rate to track yarn quality and loom mechanical conditions.
This metric establishes the baseline boundary between acceptable loom operating performance and excessive warp breakage.
Loom Performance
Loom monitoring systems aggregate stop signals from individual weaving frames to generate hourly performance metrics across the weave room. High warp stop motion rate indicates poor yarn sizing, incorrect shed geometry or inadequate yarn tensile strength. Weave room supervisors use stop rate data to identify problematic yarn lots or mechanical wear on loom reed wires.
Maintenance records log corrective actions taken to restore target loom running efficiency.
Quality Standard
Frequent warp stoppages increase fabric defect incidence through stop marks and localized warp end distortions in the woven cloth. When warp stop motion rate exceeds target limits, loom efficiency drops sharply and labor costs per meter increase significantly. Quality compliance guidelines mandate maximum allowable stoppage rates for specific weave structures and yarn counts.
Final inspection logs correlate loom stoppage records with cloth defect maps to ensure shipped fabric meets commercial grade standards.
