Shed Geometry Optimisation and Warp Tension
topic
Shed geometry parameters including shed angle, back rest height, shed crossing timing, and heald frame differential stroke are optimised for each fabric construction to minimise warp tension peak during shed formation while providing adequate shed opening for weft insertion clearance, with shed timing computer simulation enabling virtual optimisation of these interdependent parameters before physical machine adjustment.
Role
Minimises warp break rate from excess warp tension during shed formation by optimising the geometric relationship between heald frame position, back rest height, and shed crossing timing that determines the warp tension peak occurring when crossing end groups change position, with shed geometry optimisation being particularly important for fine or delicate warp yarns where tension management determines weaving efficiency.
