Savio India recently hosted a technical seminar in Ahmedabad and Rajkot in Gujarat, India and showcased a presentation on winding and splicing technologies. From Savio were present, Dr Gabriele Checchini, CEO of the Indian operations, Valter De Carli, its regional sales vice president and K Mohanraj, vice president - national sales.
Carli began the presentation by explaining the evolution of Savio, which today is a leader in the yarn finishing machine sector, operating worldwide in the manufacturing and marketing of automatic winders, continuous shrinkage and bulking winders, two-for-one twisters, and rotor spinning frames with factories in Italy, China and India.
Savio began in 1911 by establishing a small workshop specialising in repairing textile machinery, mainly looms. In 1946, it graduated to producing assembly winders and is now today a maker of state-of-the-art technologies for the various segments of the textile industry and today has now manufacturing operations, apart from Italy, in China and India.
Savio invests 5 per cent of its turnover in R&D to develop newer technologies and now is present in almost 60 countries. 2011 was a peak year for Savio, when it attained its highest sales in history and was also the year in which deliveries took almost a year due to the unprecedented orders it received that year. However, post 2011, sales have now stabilised to a level, where it is now able to serve customers quicker.
According to Carli, Savio is the world leader in winding technologies and has a massive 40 per cent global market share of the overall worldwide winders market and in China, has an even higher market share of over 65 per cent. Savio says Gujarat too has been a favourable market for the company which has seen a heavy demand for its winders.
Considering the demand for more automated technology for processing special and value-added yarns, Savio has concentrated in the area of splicing, which serves the special needs of processing value-added yarns. Savi has recently added a new splicer range, which has five models and claims that with this range, there is no yarn in the world, which cannot be expertly spliced through the use of one of these splicer technologies giving high consistency and maximum strength.
Similarly, the Polar family of winders is available in different versions like Polar M/L, Polar MR/LR, Polar E, Polar E Premium, Polar E Premium Duo Lot and Polar/I Direct Link System. This machine has been designed keeping in mind the demands of its customers in terms of increased productivity, reduced energy consumption, reduced waste and production of yarn package of top high quality.
Polar M is equipped with manual bobbin feeding and manual package doffing, while in the L model, the package doffing is automatically made by a patrolling robot, while the MR/LR version allows rewinding of packages of any taper, producing packages ideal for any subsequent use.
The main fields of use for POLAR MR/LR are rewinding of packages coming from the dyeing process, packages of different shapes and contents, packages coming from Open End spinning frames and package remains. The LR model is equipped with automatic feeding package change, while the MR model is without the automatic doffing trolley.
The Polar E model is an automatic winder with automatic bobbin feeding and automatic package doffing. Ring spinning frame bobbins are loaded into the hopper box and then placed on the Flexitray or peg to be transferred to the preparation station. Each bobbin placed on Flexitray is automatically moved to the “yarn finder station”, in order to prepare it for the following winding process, with all the operations being automised and operator free.
The Polar E Premium model has been designed to evenly process those yarn bobbins, whose formation is not originally favourable to reach efficiency, while also retaining minimum number of operators. The bobbin capacity has been increased due to the "double alternate" loading system on the peg due to which again, the higher loading rate is able to cover winding heads up to 72 spindles.
The Polar E Premium model can be also provided with a ‘Duo-Lot’ feeding system, allowing the process of two different bobbin lots concurrently on same machine. The machine is equipped with two independent hoppers, each of them feeding the dedicated winding sections accordingly. The solution of the independent end finder stations, embedded on the frame, allows the possibility to split the feeding of both lots to the winding heads selected sections.
In the Polar/I Direct Link System, the automatic winder is linked directly to the spinning frames where bobbins are uninterruptedly moved from the ring-frame to the winder. The Polar/I DLS has a direct feeding of the ring frame bobbins thus practically becoming an extension of the ring frame itself, ensuring total free flow of the materials. This solution enables a quick and efficient bobbin feeding together with a flexible interface.
