Rotary glazing machine, in particular for ceramic tiles

A rotary glazing machine for glazing ceramic tiles, comprising:

• a mobile rest plane for the tiles on which the tiles are translated according to a pre-established direction;
• a rotary glazing apparatus positioned above said rest plane;
• wherein said rotary glazing apparatus comprises:
• a first cylinder, mobile in rotation about an axis thereof, having a peripheral part which is elastically deformable, and provided with a smooth external cylindrical surface made of an elastomer material on which a plurality of cells is afforded;
• said first cylinder being driven to rotate about said axis thereof and being positionable with respect to said rest plane in such a way that said cylindrical surface can roll undraggingly and with a predetermined pressure on an upper surface of a tile transiting on said rest plane;
• at least a first doctor predisposed to operate on the cylindrical surface of said first cylinder;
• a second cylinder, mobile in rotation about an axis thereof, having at least a peripheral part which is elastically deformable, and provided with a smooth external cylindrical surface made of an elastomer material, on which surface a plurality of cells is afforded;
• said second cylinder being disposed parallel to said first cylinder and being driven to rotate about said axis thereof, and being positioned with respect to said rest plane in such a way that said cylindrical surface can roll draggingly and with a predetermined pressure on an upper surface of a tile transiting on said rest plane;
• at least a second doctor predisposed to operate on said cylindrical surface of said second cylinder;
• further comprising glaze distribution organs located upstream of said first and second doctors for depositing glaze on said cylindrical surfaces of said first and second cylinders.
