Integrating Four Point Demerit Scoring with Real Time Loom Monitor Logs
Integrating real-time loom telemetry with four-point demerit scoring automates fabric grading by mapping machine stop pulses directly to physical defect coordinates.
Reed Mark Penalty Points
Defect Quantification
Weave inspection systems allocate penalty values to fabric rolls that exhibit vertical streaks caused by misaligned comb wires in the loom. The accumulation of reed mark penalty points occurs during off-loom inspection when the cloth exhibits uneven spacing of the warp threads. This assessment helps the mill determine whether the fabric is suitable for high-end applications or must be sold as second-grade material.
Warp Alignment
Bent or worn metal teeth in the reed force warp threads to cluster together, causing alternating dense and open bands along the linen. This clustering creates alternating dense and open bands along the length of the linen, which become highly visible after dyeing. Because these defects run parallel to the warp, they are classified as major structural faults that cannot be corrected during later finishing processes.
The points allocated reflect the severity of the spacing error and are used to calculate the final quality grade of the fabric.
Financial Consequence
Excessive values in this metric force the mill to apply substantial discounts to the shipment. When the density of these errors exceeds the buyer’s tolerance, the entire roll must be rejected and redirected to less demanding commercial uses, protecting the buyer’s standards.
