Since 1911, Savio has specialised in yarn-finishing segment, being a leading supplier of winding, twisting and rotor spinning machines, with manufacturing plants across Italy, China, India and the Czech Republic. As a manufacturer of textile machinery, the company offers winding systems that are ideal for many different needs as well as supporting customers in developing new applications to meet their needs.
At ShanghaiTex, the company exhibited their Polar Evolution winding machine — a high performance, energy saving and less labour-intensive product for Chinese customers. The machine on display was a freestanding fully automated one, provided with new features to process bobbins produced by ring frames not equipped with automatic doffing device. "Premium" winder is a solution for processing yarn bobbins whose formation is not originally "favourable" to reach efficiency, for example bobbins with tangles, entanglements and misplaced yarns tail. The newly designed hopper “Pace Sorter Feeder” will optimise the bobbing feeding for a fast and smooth bobbin flow.
In addition, special solutions have been engineered for automatic devices (bobbin preparation, transport, etc.) present in the fully automatic winder models to control and process springy elastic yarns. A special ‘Lycra kit’ is available for yarn end finder station of fully automatic winding machines, to ensure the highest efficiency for the bobbin preparation in the presence of single or dual core yarns. In downstream processing, the unwinding package and the take-up speed facilitate process to be more efficient.
Savio has a full range of grooved drums to cover all yarn types, counts and downstream processes. The EVO drums offer new capabilities to optimise both the unwinding speed of the packages and the package yarn content, through variable number of turns with different winding angles. The package shape is optimised to obtain advantages for a better unwinding ratio in the downstream process, for homogeneous package density and for lower rewinding breaks.
