Roller coating machine for enamelling of glass sheets. The different hardness of the rubber lining of the roller, and the different finishing of its surface allow to graduate the quantity and thickness of the applied enamel, and thus to obtain a wide variety of effects, from the semi-transparent satin, to the opaque, to the totally opaque. The satin effect obtainable is comparable to the effect of sandblasting and acid etching, with the advantage of easier cleaning.
