AI Technical Summary
The outer working surface of the existing spinning draft rubber ring uses a flat rubber layer, which leads to weak grip on the spinning whisker strips, which is prone to relatively slippery with the whisker strips, affecting the grip synchronization and spinning quality.
A textile drafted outer pattern rubber ring is designed, and its outer layer surface is provided with an equidistant straight pattern perpendicular to the operating direction of the garden, including a crest and a trough, forming an uneven surface structure, and a transitional rounded corner is provided between the crest and a trough.
By increasing the roughness of the surface of the rubber ring, the ability to hold the spinning whisker strips is improved, the smooth movement of the rubber ring is ensured, the control of floating fibers is enhanced, and the spinning quality is improved.
