Sectional Warping Machines and Beam Building
topic
Sectional warping machines wind parallel yarn sections at defined width and length from creels of individual yarn packages, building the warp beam in sections across the beam width before beaming all sections simultaneously onto a flanged weaving beam, with drum diameter and surface speed controlling warp yarn tension and the accuracy of section length equalisation that determines warp yarn length uniformity across all ends.
Role
Prepares weaving warps by building sectional warp beams from multiple yarn packages with precise yarn length equality across all ends that prevents the differential yarn tension during weaving that would cause systematic weaving defects, with sectional warping being used for short repeat fancy yarns, small volume warps, and striped warps where the flexibility of section-by-section construction is preferred over direct warping.
