Rieter's R 40 Offers High Productivity, Cost Savings
Switzerland-based Rieter Spun Yarn Systems reports its R 40 rotor spinning machine provides
improved productivity, efficiency and yarn quality; in addition to lowering costs and energy
The R 40 utilizes Rieter's SC-R spin box, which integrates piecing and package change in a robot assembly. An optimized take-off angle facilitates reduction in yarn twist, while maintaining spinning stability and increasing delivery speed by 5 percent.
The R-40's 245-millimeter (mm) gauge accomodates larger sliver feed cans than other rotor spinning machines. Feed sliver of up to 7 ktex can be processed, and almost all yarn counts can be spun from the same feed sliver. Packages produced have diameters of up to 340 mm and weigh up to 5 kilograms, resulting in package-handling and transport cost savings of more than 20 percent.
Rieter reports the combination of up to 320 SC-R spin boxes in a single unit provides up to 10 percent higher production than conventional rotor machines. Rotor speeds on the R 40 reach up to 150,000 revolutions per minute (rpm), and energy consumption is reduced.
