Stable yarn package formats for elastic materials

Minimisation of bulging-out package flanks

Packages of elastic materials, such as elastic core yarns, Wool or Wool-Siro yarns, tend to have their shape badly deformed by bulging-out flanks. Influencing factors are the yarn tension, the package contact pressure and the elasticity of the yarn. The integrated Variopack FX system minimises bulging out of the package flanks very effectively.

Advantages of Variopack FX:

  • Dimensional stability of the packages, even with large diameters.
  • Optimum unwinding performance.
  • Troublefree handling and creeling in downstream processing.
  • Uniform dyeing of the packages.

 

Optimized processing of packages with elastic materials.

The Variopack closed-loop control circuit coordinates yarn tension and package contact pressure during the build-up of the package in such a way that there is hardly any bulging-out of package flanks.
