The Klieverik belt calender can be used to bond individual fibres of a non-woven or to melt the added BiCo material only. Klieverik offers the belt calender as the most economical solution for technical applications. The investment is relatively low compared to other machinery concepts on the market.
Due to its long contact time of several seconds, the pressure required can remain low. Optimizing the parameters – contact time (speed), temperature and pressure, the desired effect like higher tensile strength, surface smoothness, hand and (calibrated) thickness can be obtained.
Surface weights of up to 2000 gr/m2 can be easily processed. Our calenders are used for products like:
