SICAM s.r.l.

Calenders

Smoothing calender

The Sicam smoothing calenders are used to obtain a particularly smooth surface on the non wovwn. Thanking to the high temperature and to a proper adjusting of the roll speed the final nonwoven has not single fibers in evidence on the surface. This calenders are usually are usually uninstalled after ovens foe the production of thermobonded waddings. According to the kind of non wovewns and to the required smoothing effect, the surface of the roll can be Teflon coated or chromium plated.
