Since 1911, Savio is specialised in the yarn-finishing segment, being the leading supplier of winding, twisting and rotor spinning machines, with manufacturing plants spanning over Italy, China, India and Czech Republic. As a manufacturer of textile machinery, Savio offers winding systems that are ideal for many different needs, supporting customers in the textile challenge of developing new applications to meet their requests.
Savio exhibited in Shanghai the Polar Evolution winding machine: a high performance, energy saving and less labor-intensive product for the Chinese customers.
Polar winding machines have been recently developed to the Evolution series, gathering all the innovative solutions in terms of technology, efficiency, quality output and maintenance. A further step for Polar family to catch the world of I.T. connectivity and the new fibres applications.
The machine on display will be 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 "favorable" to reach efficiency, for example bobbins with tangles, entanglements and misplaced yarns tail. The newly designed hopper “Pace Sorter Feeder†will optimize 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, in order to grant the highest efficiency for the bobbin preparation in presence of single or dual core yarns.
In downstream processing, the unwinding behavior of the package and the take-up speed facilitate process to be more efficient and geared to benefit.
Savio has now a full range of grooved drums to cover all yarn types, counts and downstream processes. The EVO drums offer new capabilities to optimize 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 in order to obtain advantages for a better unwinding ratio in the downstream process, for homogeneous package density and for lower rewinding breaks.
