Description

Technical Field

[0001] The utility model relates to the technical field of leno fabric weaving, in particular to a twisted warp active delivery device for leno fabric weaving. Background Art

[0002] When weaving leno fabric, the twisted warp yarn moves left and right around the ground warp to form a leno structure. When the twisted warp yarn moves to the other side of the ground warp and is lifted up with the twisted heddle, a twisted shed is formed. At this time, the twisted warp yarn must have sufficient elongation to ensure that the twisted warp yarn can be lifted up smoothly. When the twisted heddle falls, the previously stretched twisted warp yarn must be retracted in time to ensure the normal tension of the twisted warp yarn, form a clear weaving shed, and complete the weaving.

[0003] The traditional control method generally involves adding a weighted roller to the warp yarn. Before weaving, a certain length of warp yarn is released. The roller presses the warp yarn down to a certain height, forming a certain inclination angle and reserving a certain amount of warp yarn. When the corresponding heddle is lifted, the warp yarn is lifted, and the warp yarn drives the roller up, changing the inclination angle of the warp yarn, so that the warp yarn has a certain length of elongation and is released to the weaving fell. When the heddle falls, the warp yarn recovers its previous inclination angle under the action of the weight of the roller, and the elongation of the warp yarn previously released to the weaving fell is recovered, ensuring that the warp yarn is always straightened to ensure weaving progress. This method releases the tension of the corresponding length of warp yarn and causes great friction between the warp yarn and the ground warp yarn, which can easily lead to breakage of the warp yarn and the ground warp yarn. It is also easy to cause wear of the heddle. Utility Model Content
