AI Technical Summary
When producing heavy-duty cord fabric, existing looms use high-density, high-denier warp yarns, which are prone to loosening and falling off, resulting in uneven warp density and difficulty in uniformly lifting the heald frames, thus affecting weaving quality and efficiency.
A high-density warping mechanism is adopted, which enhances the tension of the warp yarns by setting the first, second and third tension rollers and using different diameters and wrap angles of the smooth roller and the rubber roller. A yarn threading frame is set between the traction roller and the heald frame to ensure the uniform distribution of the warp yarns.
It effectively avoids warp slack, improves the precision of warp yarn arrangement, reduces yarn breakage rate, and enhances weaving quality and efficiency.
