Finishing Calender

Mostly, Finishing Calenders are used as an accessory part to the thermo-bonding process.

Examples are the surface finishing, hardening, the calibration of the Nonwoven to a defined thickness and density by volume and lamination.

For these applications either Cold Calenders or Hot Calenders can be used in dependence on the requirements to the end product.

Merely, if the Nonwoven is very light, to ca. 40 g/m², a adequate thermo-bonding by means of Calenders will be achieved.

The material is guided through two horizontal arranged rolls with defined gap. To guarantee a perfect heat transmission, the required pressure on the web can be achieved by means of pneumatic cylinders or precision worm gear jacks.

A sturdy frame with less stiffening, less vibration and short process tolerances guarantees a constant contact pressure and a minimal temperature difference across the whole working width.
