OE Spinning Quality Control

Quality monitoring: online evenness monitoring (capacitance-based sensors measuring CV%, thin/thick places continuously on each rotor position with automatic rotor stopping for excessive variation), periodic Uster testing (comprehensive quality report comparing to ring equivalents and OE standards), visual inspection (wrapper defects, trash marks, slubs), and package building quality (winding tension uniformity, package density, shape). Critical control points: sliver quality input (CV%, neps affecting output directly as no drafting to improve uniformity), opening roller condition (wire clothing sharpness, replacement every 3,000-8,000 hours depending on fibre type), rotor cleanliness (regular cleaning every 8-24 hours removing fibre deposits, trash accumulation reducing groove volume and causing defects), and bearing condition (vibration monitoring, temperature monitoring for predictive maintenance).
