Abstract
Description
technical field
[0001] The invention relates to a device for producing woven cloth, in particular to a part of a needling machine. Background technique
[0002] The hook teeth on the traditional lancets are impacted and pressed by a tool similar to a chisel. The hooks produced inevitably have right angles, acute angles, and planes. These right angles, acute angles, and planes have the following defects on the fibers that are hooked:
[0003] 1. As a result, the sliding resistance of the fibers between the barbed hooks will be increased, and the resistance of the needles during the weaving process will be increased, resulting in excessive broken needles.
[0004] 2. Because the sliding resistance of the fibers between the barbed hooks is large, the direct contact with the high-speed moving fibers at right angles will generate force, which will cause fiber damage and breakage, resulting in uneven surface of the woven product, reduced fiber entanglement, and vertical and horizo...
