Pakistan Textile Journal. October index

Founded in Pordenone in 1911 as a small workshop to manufacture textile components for the local market, Savio Macchine Tessili is one of the leaders in the yarn finishing machine sector ranging from wool, cotton, linen and silk to synthetic fibres. In 2001 Savio became part of the Itema Group, Savio Macchine Tessili brand is known for manufacturing and marketing: automatic winders, two-for-one twisters, electronic assembly winders, winders for continuous bulking and shrinkage, open-end rotor spinning frames. Savio also operates a technical assistance and spare parts network throughout the world to ensure quick and efficient service to customers. Savio is represented in Pakistan by Acmatex Corporation.

The brand new POLAR automatic winder; in all its versions: from manual feeding and doffing up to the linked version with automatic doffing is Savio’s portrayal of the future winding technology. Another new product in the twisting technology field is Savio Twist&Twist.

COSMOS which is the latest generation two-for-one twister: simple, reliable, essential, in other words, there’s no compromise on quality

The FlexiRotorS 3000 / Duo-Spinner completes the range of products on show. In the meanwhile, thanks to the design features of FiexiRotorS, Savio has set up a profitable and effective collaboration with AMSLER, for programming effect yarns.

Polar has been highly popular with customers in Pakistan since its debut at Textile Asia 2006 exhibition in Karachi (Pakistan). The innovative solutions proposed by the new generation of these winding machines have met the winding demands of Pakistani customers. By being part of the Itema Group and, in particular; the close synergy with Itema Weaving, it has also made it possible to anticipate the most suitable winding solutions to optimize weaving productivity.

The link solution that, with the new link type “BUFFER” permits direct quick and effective feeding of spinning frame bobbins besides total interfacing flexibility with all bobbin movements (single or multi-step).

A great number of important and emerging markets are investing in this type of machine, mainly because it is very difficult to find local labour and also because of the qualitative and productive advantages that this solution necessarily entails.

So in these countries Savio is seeing a rapid transformation from systems with spinning frames without doffing and free-standing winders to the completely automatic link solution.

Special attention is given to “compact” and/or condensation spinning where this type of solution is required due to the high value of the yarn and also because it allows the quality of the bobbin to be monitored by means of the spinning frame spindle identification system.

This solution, which entails manual loading of the bobbins with manual and automatic package doffing, is presented with:

v different solutions for air splicing (Air splicer), water splicing (Water splicer), heat splicing (Heat splicer) and mechanical splicing (Twin splicer), in other words the “Total Splicing System” that completely covers all cut cotton, wool, linen and silk fibre materials.

v various types of bobbin feeding from 180 mm to 450 mm with different materials and counts.

v take-up packages with different taper ratios with electronic on-off antipatterning system and C.A.P.

v packages for dyeing to which monitoring of package density with the changing diameter is associated (CAD).

v a highly efficient automatic doffing trolley, of new conception, completely incorporated with the machine’s monitoring and control system.

COSMOS is another one of Savio‘s proposals in the traditional two-for-one twisting field, designed specifically to be highly economical by means of constructive solutions that mean a lower investment and less energy consumed.

Machine production, quality of the package and of the processed yarn together with technological flexibility is the essential requirement for each textile market. These attributes are maintained at the same level as the Geminis and Geminis S models which will continue to be part of the range of products being offered.

If the twisting operation transformation costs were to be analyzed in countries where productions are ongoing today we would see that the predominant part is put into the investment and in energy

This calls for the need to propose a machine that requires a much smaller investment together with a range of spindles optimized by:

v geometries and implementation techniques that will maximize feeding package weights,

This is a brand new technology that by means of a “dual twisting stage” lets you increase production by at least 33% consuming the same amount of energy used for the conventional 2x1 process.

The weights and dimensions of the assembly wound packages in feeding, the interventions for maintenance and the room operator’s work loads are the same as the conventional process.

This process does, in fact produce a twisted yarn by forming two yarn balloons - one that is more external with an “S’ rotation and the other internal with a ‘Z” rotation achieved by means of a “mechanical differential speed system” that creates a triple twist of the yarn with each turn of the spindle.

This Savio patented device has been made in collaboration with SKF who, built and tested it.

The increase in production mentioned earlier automatically leads to an equivalent reduction in the number of spindles and, therefore, in system dimensions, saving on the space taken up, conditioning costs, lighting and a reduction in noise.

The return of the investment which of course differs from country to country according to the different local energy costs, is very quick and of absolute interest.

The T& T device can be applied on all spindles currently in the SAVIO range, that is, on the Gemini, Geminis S and Cosmos twisters.

The Savio FlexiRotorS 3000 / Duo-Spinner rotor spinner model is the machine that can meet the most diversified requirements of the Open End market.

Savio’s choice to conjugate the concept of maximum production capacity with yarn quality together with production flexibility seems to be more and more the winning factor in this sector; even for up and coming markets.

By using the Suessen spinning unit together with the separate fronts solution and a completely electronic machine, where the work parameters are all set and monitored by the centralized PC, give the customer the guarantee of having the ideal solution at his disposal to control production.

Downtime for material and/or count change, the possibility to plan production for a single side instead of for the whole machine, programming the 2, 3 or 4 automatic trolleys intelligently make this machine truly “unique” out of all those currently offered on the market.
