RFTC21B Direct Twisting Machine for Tire Cord

Direct Twisting Machine for Tire Cord is a one-time merging using a single processing, which reduces the number of steps compared with the traditional twisting method. So the yarn capacity is also more compared to the two-for-one twister machine. This increases production efficiency, reduces labor, and reduces energy consumption. At the same time, due to the reduction of the processing, the wear (strong loss) is correspondingly reduced, which is more suitable for the high strength requirement of Tire Cord. lt has become the most suitable professional machine for producing high quality yarns such as tire cord, industrial yarns and carpet threads. This direct twisting machine is designed and developed by our company for the relevant process requirements.
