Beam Building and Flanged Beam Specifications
topic
Warp beam specifications include flange diameter up to 1000 millimetres, barrel diameter of 120 to 200 millimetres, barrel width from 180 to 400 centimetres, and maximum yarn layer diameter governed by the let-off mechanism of the destination weaving machine, with beam hardness measurement by shore durometer assessing yarn layer compactness and uniformity that must match weaving machine let-off system requirements for smooth controlled beam unwinding during weaving.
Role
Ensures warp beams are physically compatible with the weaving machines they supply and wound with the yarn density that enables smooth let-off during weaving, with beam hardness uniformity across the beam width and along the warp length being critical for consistent warp tension during weaving since hard and soft sections of the beam unwind at different tensions causing weft density variation in the fabric that manifests as horizontal bars visible in the finished cloth.
