Quality Inspection at the Loom: Catching Weaving Flaws Before Washing and Finishing

Every carpet maker has experienced the heartbreak of a freshly washed rug emerging from the shearing table with wavy edges (bowing), irregular pile thickness, or mismatched pattern borders.

The High Cost of End-of-Line QA

In standard manufacturing, Quality Assurance at the end of the line works fine. In rug making, it is catastrophic. Once latex is cured or knots are clipped, repairing a foundational weaving flaw takes days of manual re-burling or results in total rejection.

The In-Loom Inspection Checklist

• Warp Tension Verification: Ensure consistent tension across left, center, and right edges to prevent skewed geometric lines.
• KPSI Density Rulers: Count knots per square inch at 3 different sections of the active weave to prevent shrinkage discrepancies.
• Pattern Naksha Alignment: Verify that border widths match CAD specifications within a +/- 3mm tolerance.
• Back Knot Cleanliness: Ensure weavers do not leave loose yarn tails embedded in the foundation that could cause lumps.
