Rieter Winding Suction Nozzle Upgrade: More Yarn, Less Energy Use

After upgrading the suction nozzles on their 32 winding machines, Sanyang Textile Co., Ltd., China, saw an increase in yarn production of 3% and a reduction of 13% in energy use. The flow-optimised, aerodynamically designed suction nozzle enables efficient upper yarn search and pickup from the package. This results in a 55% reduction in red light percentage and a significant reduction in the operator's workload.

Sanyang Textile is a leading supplier of fine yarns, with counts ranging from Ne 40 to Ne 120. In response to growing demand for knitting yarn, the company adapted its processes to meet evolving market requirements. However, due to intense competition, achieving high margins is challenging, pushing the company to reduce manufacturing costs. As a result, increasing productivity and lowering energy consumption became top priorities. The initial focus was placed on their 32 winding machines, Autoconer 338, which have been in operation for more than 20 years. The customer was looking for suitable upgrade solutions to improve productivity and energy efficiency.
