A 1929 article from the first issue of The Melliand explaining a defect in rayon fabrics, a periodic loose-warp effect that shows as spotty bands across taffeta. The author attributes it to warp beamed too loosely on the sizing machine, so the warp tightens on the beam during weaving and then feeds excessively when the paper drops. He gives remedies: wind leader aprons with full sizing-machine tension, add beaming paper, and keep beaming tension above loom tension. Three figures show a taffeta swatch, a warp cross-section and a loom beam.
