Quality Inspection of Warp Beams
topic
Warp beam quality inspection includes visual examination of beam end faces for end layering regularity and absence of wild ends, hardness measurement across beam width and comparison of warp and non-warp side hardness balance, end count verification by counting ends per centimetre at beam face, and broken end identification by visual inspection of beam surface with the warp sheet spread over an inspection board that reveals missing ends as gaps in the parallel yarn array.
Role
Verifies that warp beams meet quality specifications before they are transferred to sizing or weaving where warp defects discovered after processing commitment represent significant waste of sizing and weaving time, with beam inspection being the quality gate that prevents defective beams from consuming resources in subsequent processes that cannot correct the warping defects of missing ends, tension non-uniformity, or incorrect end count that cause weaving problems.
