HOT CALANDER

A hot calender is the simplest and most effective solution to transform a standard needled punched felt into a high technical product, giving immediate benefit and extra added value. This is achieved without any modification within the existing line.

Typically a calender is installed in-line, directly after the last needle-loom, but it can be installed off-line in order to serve more than one producing line (Calender working speeds are faster than a standard felt production line)

In one single step, calenders are able to make an excellent finishing job to the felt, with the following advantages:

- Calibrating accurately the product to the required thickness;

- Increasing the mechanical properties, by thermofixing the fibers;

- Reducing the peeling effect;

- Reducing transport costs (up to 60 - 70%), by reducing the roll diameter of the final roll.

Special model for embossing of the felt.
