[0002] The yarn doubling device is a key equipment in textile machinery used to merge multiple yarns into one yarn. Its main function is to accurately merge the scattered yarns into one yarn while ensuring uniform tension and twist through reasonable mechanical design and control system, so as to meet the requirements of fabric production for yarn strength, uniformity and stability. The device usually includes multiple links such as conveying, tensioning, doubling, guiding and winding.
