Cold Milling


Innovation goes through the temperature. We present the latest generation of milling machines, the Cold Milling drum . This drum represents the maximum of technological innovation and allows you to work regardless of the external environmental conditions, be they high or low. Hot or cold Cold Milling keeps the temperature constant, without compromising the moisture of the leathers.

The drumming revolution

Cold Milling® is the new technology designed for the most sensitive leathers. Designed for cold drumming , it allows temperature control that does not interfere with the balance of the internal environment in contact with the hides.

In many markets there is an increasing demand for soft and smooth leathers especially from non-mineral tanning which are particularly sensitive to heat. For this reason, temperature control must be more accurate and fulling is no exception.

After years of research, the innovative technology allows to keep the temperature of the environment in contact with the skin controlled in a totally independent way from the external environment . This allows to avoid thermal shocks to the leathers, realizing a more accurate control of temperature and humidity regulation, and achieving reproducible results regardless of the seasons. The effect is greater uniformity between the hides processed during the year or between factories located in different continents.

The whole line of Black Line drums can be chosen in the Cold Milling® version .

We study every shape

a design that surprises


Curved automatic conveyor

(for PACA version)


The refined curve of the automatic belt allows you to follow the shape of the drum, maintaining a constant space from it.

This avoids areas of shrinkage, cause of crushing and possible damage to the processed leathers.


compact security


The innovative system allows for maximum opening, extending within the overall dimensions of the barrel.

This allows you to make the most of the positioning of the drum, even in rooms with not particularly high ceilings or under special shelters.
