Background
The three-strand straight twisting machine is mainly used for the industries of producing tire cords, industrial filter cloth, high-quality carpets and the like. Chinese patent
In a method and a twisting device for directly twisting three-ply yarn into a thread disclosed in document CN101429693A, two spindles form a station to realize one-time twisting of three-ply yarn. However, when the three-ply yarn order is insufficient, two of the two twisting stations can be used for normal straight twisting, and the three twisting stations cannot be used for normal straight twisting, so that the waste of equipment is caused. The inventors have found that this is because the overfeed roller speed for the three twist stations is different from the overfeed roller speed for the two twist stations. Chinese patent document CN 210458471U describes a twisting machine for producing three-strand wires by implementing three-strand twisting in such a way that each wire guiding device is designed to have a different diameter. This construction makes the three-ply yarn unusable for normal straight twisting processes as well.
