Description

Technical Field

[0002] The common steel reeds of existing shuttle looms are steel reeds with equal reed densities on the upper and lower reeds, and the upper and lower heights are approximately 10CM, which can only meet the weaving requirements of ordinary equal-warp density fabrics. The existing steel reed structure and processing cannot meet the weaving requirements. First, the structural strength and stability are insufficient due to the increase in the overall height. Second, due to the differences in the size of the reed blades in the fan-shaped reed processing, the tension of the reed blades in different positions is different. Some reed blades are tight, and some are loose, resulting in poor weaving quality. In order to meet the variable warp density and variable diameter requirements of variable diameter tubular fabrics and wide and narrow bands, we need a fan-shaped steel reed with different reed densities on the upper and lower reeds and a height of about 20CM. For this purpose, it is necessary to provide a steel reed device for variable warp density weaving. Summary of the invention
