C-Win: a new level of efficiency in Winding

High-speed continuous motion solutions are the hallmark of G.D, proudly holding a century of innovation and excellence in manufacturing advanced machinery for the tobacco industry. Our expert engineers are now leveraging this valuable legacy in the winding process, a critical and delicate step in battery manufacturing that significantly impacts the final product quality. 

Meet C-Win, a high-speed winding solution designed to produce high-quality jelly rolls for the assembly of cylindrical lithium-ion battery cells. With the primary goal to contain TCO for a traditionally cost-intensive process step, this solution shows improved throughput and product quality compared to winders available on the market, all in a compact footprint. 

During the unwinding of the electrode reel, the C-Win is designed to maintain a strictly constant speed, however high, keeping the material tension stable. This way, the stress peak effect on the electrode is minimized, resulting in lower material discard and higher quality of the final product. 

Precision is one of the keywords for this machine: thanks to the advanced alignment management system, checking the electrode position all along its journey through the machine, the reel is automatically placed on the expected set-point before cutting out each single jelly roll, ensuring the utmost accuracy. 

The C-Win is also requiring limited intervention from operators, as the reel changeover task is performed automatically, including preparation, reel cutting and the application of tape on the electrode or separator. Thanks to the optional automatic modules such as robotic infeed arm and AGV fleet system, this solution is ready to be part of a fully automated plant.
