Warp Tension Measurement and Control During Warping
topic
Warping tension control maintains uniform tension across all warp ends and throughout the warping run using tension measurement rollers detecting total warp sheet tension and individual end tension sensors at selected positions, with closed-loop control adjusting warping drum or beam drive speed to maintain target tension as package diameters decrease, achieving tension uniformity of plus or minus 5 percent across all ends and throughout the warp length required for uniform warp beam build.
Role
Governs the warp beam build quality and unwinding consistency that directly determines sizing and weaving performance, with tension non-uniformity across ends causing differential yarn lengths in the warp beam that produce fabric defects from uneven shed formation, and tension variation along the warp length causing beam hardness variation that produces different yarn extension during weaving from tight and loose sections of the beam affecting fabric pick density uniformity.
