System of leasing rods for weaving loom - supported by levers to convey rise and fall motion, to reduce tension in warp sheets

摘要

A system for leasing rods for a weaving loom is disposed across the rear end of the loom between the heald frames and the yarn support mounted above the warp beam. The leasing rods are supported together, one above the other, by a system of levers which can convey a rise and fall movement at a cycle double the length of the cycle of the movement of the loom sley. Previous leasing systems have remained fixed during the weaving process. The rods of the present invention are used to reduce tension on the warp sheets, in partic., the sheet having the greater tension at the moment of beat-up.
