Tensioning of Fibers

Yarns and textile threads – always under tension

  • Pressure precision and stability
  • Low energy consumption
  • High control dynamics

When winding wires or textile threads, it is important to maintain the tensile stress at exactly the same value as the reel diameter increases. At the same time, pressure rollers must be applied against the yarn reels at constant pressure. The requirements are similar for production operations in which plastic films or wires must be exactly wound.

In these applications, piezo-controlled proportional three-way pressure valves made by HOERBIGER have been successfully applied because of their precision and large pressure control range.
