🧵 Loom Shed Opening: Warp Tension, Weave Float Length and Cover Factor (2D)

Side view of a loom where the heddle frames open the shed and stretch the warp yarns, with the weave structure repeat shown beside it. Set shed height, heddle distance, pretension, yarn stiffness, loom speed, thread density, yarn diameter and plain, twill or satin weave, and see the warp tension rise and fall each pick. Geometry and cover are computed, with five numerical checks in the page. A 2D companion to the 3D weaving laboratory.
