Warp Break Repair Time and Restart Quality
topic
Warp break repair time is the stop time from break detection to loom restart that is the primary efficiency loss multiplier for break rate, comprising the loom stop time, operator response time, broken end location time, threading repair time through heddle and reed, knot tying or splicing, start-mark prevention sequence, and loom restart, with average repair times of 2 to 5 minutes per break for standard fabrics representing the break-related efficiency loss that multiplied by break frequency determines the total efficiency reduction attributable to breaks.
Role
Quantifies the production loss per break that together with break frequency determines the total warp break contribution to efficiency loss, with repair time reduction through operator skill training, improved lighting for broken end location, better access tools for heddle threading, and automated repair assistance systems providing efficiency improvement complementary to break rate reduction, since halving repair time provides equivalent efficiency improvement to halving break frequency.
