Savio Unveils Technology

Italian machinery company is set to present two brand-new spinning innovations at ITMA 2003.

TW Special ReportSavio Unveils Technology Italian machinery company is set to present two brand-new spinning innovations at ITMA 2003.
Savio's FlexiRotorS 3000 Duo-SpinnerITMA 2003, Birmingham, England, has special significance in more ways than one for Italy-based Savio S.p.A. In 1965, Savio, already a global company, founded Savio/GB. An agreement between Luciano Savio and Ronnie Greenbank permitted Savio/GB to manufacture Savio machines in England under license. This partnership accelerated the expansion process for Savio machines not only in the United Kingdom, but also throughout the British Commonwealth. For this reason, Savios attendance in Birmingham is not just a duty, but also a visit to see old friends.In addition to seeing old friends, the exhibition marks Savios unveiling of two brand-new, never-before-seen technologies the FlexiRotorS 3000/Duo-Spinner and the LustreS/Direct Mercerizing Machine. According to the company, each development represents an extraordinary step forward in its particular sector.We worked hard to develop the rotor-spinning frame of the third millennium [FlexiRotorS 3000/Duo-Spinner] as the most advanced proposal for the entrepreneurs of this new era, said Daniele Pellissetti, order administrator director. This spinning frame opens a new chapter in the history of rotor spinning.In addition, the location of ITMA 2003 the cradle of the textile industry is the perfect location for the first presentation of a machine that carries the baton handed over by the English chemist John Mercer, inventor of the mercerizing process, who lived in the mid-17th century, Pellissetti said. Savio took this baton and honors it by presenting the LustreS/Direct Mercerizing Machine, the new Savio winder for continuous mercerizing. A door opens in a sector that for more than a century and a half has been waiting for this new machine, which is a true milestone.FlexiRotorS 3000/Duo-SpinnerThe new Savio spinning system boasts lower investment levels thanks to higher production capacities compared to those of conventional open-end machines. These higher capacities are attained through a high-performance spinning unit, together with what Savio refers to as intelligent, highly efficient and reliable end-piecing trolleys.Savio states total control of yarn-winding conditions guarantees the production of packages with an even and variable density. These desired characteristics are due to a system unhindered by any mechanical parts, which can provide better yarn quality with a certified package.The FlexiRotorS 3000/Duo-Spinner makes excellent packages to feed the weaving machines, with parameters the likes of which have never been seen before, said Pellissetti. Take-up at variable density; centralized adjustments of the counterweight; and friction, speed, twists, cross-winding angle, anti-patterning and tension are all operations that can now be done by simply pressing a key on the computer on the spinning managers desk. Flexibility is enhanced because yarn with different counts and parameters can be spun on each front. Additionally, the intelligent trolleys go to the aid of the front requiring more attention. Because both fronts can be used separately, lot change times are halved, and the actual number of lots is minimized. Packages can be made up at extra-high density with a weight up to 30-percent greater than what is possible with the conventional open-end machines with the same diameter. Besides a higher machine yield, the machine offers a reduced consumption of tubes, reduced packing and shipping costs for the yarn produced, less yarn waste, as well as fewer package changes on the warper and loom creels.
Savio's brand-new FlexiRotorS 3000/Duo-Spinner is the company's latest rotor spinning machine.Extremely Easy To UseSavio also claims the FlexiRotorS 3000/Duo-Spinner is clean, safe and efficiently maintained. Working parameters are set quickly and easily with clean hands. Savio states that by completely eliminating all gear-type control units, machine operation is taken to even higher safety levels. Each machine is automatically and constantly monitored, and can be controlled on-line by the operator or spinning manager. Also, each maintenance job can be programmed for each machine front, halving machine downtime costs, eliminating costs for controls and consequently increasing the overall capacity of the spinning unit.
Computer controls on the FlexiRotorS 3000/Duo-Spinner make operation simple and flexible.LustreS Direct MercerizingLustreS, a name derived from the characteristic luster that describes a mercerized yarn or fabric, is a process developed by Savio that concentrates all the separate operations necessary to mercerize cotton yarn into a single machine. The idea for the machine was born in Savios marketing and technical departments, and then was developed and implemented by the companys team of engineers. The LustreS treatment is continuous, starting with a creel holding 24 packages. Yarn from each package travels along the enhancing path and is finally collected in single packages on Savios ORION winding heads. Each operation of the LustreS is automatically and constantly monitored, and can be controlled on-line by the operator or mill manager. According to the company, the automatic LustreS system allows the mercerizing cycle to be used by any spinning mill for a very modest investment. Whats more, besides the huge investment savings, the quality of the yarn treated is extraordinary, far superior to the traditional quality obtained with the hank cycle, Pellissetti said. The continuous Savio mercerizing treatment is regular and absolutely even, while the hank process due to the structure of the hank itself with cross-winding of the yarn and its thickness is irregular. So, at the dyeing level, the Savio yarn has no streaks, with uniform luster in each area of the fabric.Because the whole cycle is concentrated in just one machine, there are significant savings on maintenance costs, according to the company. Maintenance is further facilitated by the machines monitoring and control system. Besides a reduction in labor, the simplified, concentrated process and advanced technologies in the new machine offer increased safety.The development of the LustreS is something we at Savio feel will have a great effect on the cotton sector and create possibilities for yarn manufacturers around the world, added Pellissetti. Possibly, the cotton sector will never be the same again. October 2003
