The thermal processing of carbon, glass and aramid bers as well as of high-tech composite materials often requires high temperatures in calendering. For these cases WUMAG TEXROLL has developed the GT400 Roll Systems.
Temperatures between 50 – 400 °C are generated on the steel roll surfaces with direct electrical heating. With individually controlled heating zones a temperature uniformity of +/- 2 °C across the width and within the complete temperature range is possible. The GT400 series calenders are modular designed and can be „Plug and Play” started up at customers site. Hardened and chrome plated steel rolls are utilized in nip mode or with a gap setting. The setup can be amended by tempering rolls and winding systems.
