Warp Separation and Lease Reed Systems
topic
Lease rods and separation combs positioned after the size box drying section separate individual sized warp ends that have adhered during immersion and drying, preventing end-to-end bonding from forming inter-end bridges of size that would cause multiple-end breaks when the weaving machine sheds apart adjacent ends, with separation rod geometry and position adjusted to match yarn type and size adhesion tendency.
Role
Prevents the most damaging sizing defect of yarn-to-yarn adhesion that causes multiple simultaneous warp breaks during shed formation on the weaving machine, with effective separation rod action being essential for sizing recipes with high adhesion tendency particularly in synthetic and blended yarns where inter-fibre bonding from thermoplastic size components creates stronger inter-end adhesion than in cotton yarn sizing.
