After an accurate study and long time testing, Gemata has created and patented the new 'G' type REVERSE rollers, particularly indicated for the finishing of soft skins, usually harder to feed in, and to create smooth and polished surfaces.

The rollers installed in the new models of the Gemata machines, using the particular structure of the transport belt, allow to obtain exeptional results in the finishing:

• Easier feeding of thin and soft skins.
• Complete desappearence of the light marks left by the engraving on the surface of the finished skin.
• Better speading of the chemicals creating a mirror-like surface.
• Complete desappearance of the uneven shadows caused by the adhesion of the edge of the skin with the roller, very frequent when finishing smooth skins with viscous products.
• Wider range of capacity when varing the chemicals' viscosity.

Set parameters: conveyor speed (10 m/min) and cylinder speed (30 m/min).
Higher figures refer to the first coat on buffed leather and decrease in the following layers.
This table is purely indicative. The capacity (in g/ft² wet)varies depending on the working speed and on the product's viscosity. Increasing the product's viscosity decreases the roller's capacity. The skin preparation is just as important in determining the absorbance and, therefore, the weight of the material deposited.
