Electronic Length Measurement and Batch Control
topic
Warping length measurement uses precision measuring rollers with optical or magnetic encoders counting roller revolutions with accuracy of plus or minus 0.1 percent of measured length, automatically stopping warping at the programmed length for each beam to ensure that all beams in a multi-beam warp for one loom have equal yarn length within the tolerance required for simultaneous beam exhaustion at the same warp change point in the weaving schedule.
Role
Ensures that all warp beams supplying a single weaving machine carry equal yarn length that enables simultaneous beam exhaustion and warp change rather than progressive beam depletion that would create frequent partial warp changes disrupting weaving efficiency, with length accuracy being particularly critical for high-count multi-beam looms where small length discrepancies between beams cumulate over long warp runs to significant differences in remaining beam diameter affecting warp tension consistency.
