RST21 – Integrated drawing frame



RST21 – Integrated drawing frame

This intersecting drawing frame is used for the spinning preparation of synthetic fibres after the stretch-breaking process, as well as in tow-to-top and defelting/blending cycles.
The main drawing head is the ST21 model which guarantees a high working speed and the perfect fibre control, thanks to a limited draft gauge range.
The high defelting and feeding load capacity allows a great number of combinations on the creel (20 to 36 slivers).

The details that make a difference

  • Large defelting area for a higher feeding load and a better blending and homogeneity of the materials
  • State-of-the art electronic auto-leveller for the perfect adjustment of the outgoing sliver
  • TC7 chained head: high working speeds and a perfect fibre control, thanks to a limited draft gauge
  • Perfectly cleaned working areas thanks to a combined air vacuum and compression system for the cleaning of combs and chains
  • Material feeding path designed for the maximum linearity with a continuous slivers control
