The GT 400 Hightemperature Calender

For the thermal treatment of carbon, glass and aramid fibers as well as for high-tech composite materials, it is often necessary to generate particularly high temperatures in the calender.

WUMAG TEXROLL has developed the GT 400 roller systems for these cases.

Direct electrical heating of the steel rollers generates temperatures of 50 - 400 ° C on the roller surface. Individually controlled heating zones ensure a temperature accuracy of +/- 2 ° C across the width and the entire temperature working range. The modularly constructed calenders of the GT 400 series are fully assembled and can be put into operation at the customer's “plug and play” level. The hardened and chrome-plated steel rollers are driven in the nip or on the gap. The calenders can be expanded with tempered rolls and winding systems.

Features of the GT 400

  • GT 400 roller systems
  • Temperature accuracy +/- 2 °C
  • Operation temperature 50 – 400 °C
  • Nip or gap mode
  • Integrated heating or cooling rollers
  • Compact design
  • „Plug and Play”
