The invention provides a three-ply direct twisting
machine and a method for directly twisting three-ply filaments into a thread, including two-ply twisting spindles and three-ply twisting spindles, and the two-ply twisted
yarn twisted by the two-ply twisting spindles is fed in the first overfeed After the component is wound n times, it is transported to the long outer
yarn tube of the three-ply twisting spindle through the wire guide device, and then transported to the three-ply twisting
assembly to form a three-ply twist outer
yarn balloon, which is twisted with the three-ply twist inner yarn to form a three-ply twist yarn , conveyed to the finished
package; at the overfeed speed of the first overfeed
assembly, the size of the three-ply twisted outer yarn
balloon is controlled. The invention overcomes the interference of the speed of the overfeeding
assembly in the prior art on the shape of the three-ply twisted outer yarn
balloon, can obtain a stable energy-saving small balloon, and the speed of the twisted yarn conveyed by the first overfeeding assembly and the second overfeeding assembly It can be independently adjusted to match the winding speed of the three-ply twisted yarn to obtain the ideal
package density and improve the quality of the finished
package.
