Abstract: A motorized chuck-bearing group for a printing machine, powered by a brushless motor, comprises a casing housing a stator coil and a rotor, controlled both in velocity and activation times by a control circuit comprising an encoder device, in which a shaft supports permanent magnets in a peripheral arrangement, the shaft being coupled, internally of the casing, to the encoder device and extending outside the casing such as to support a chuck which rotates an object to be printed.

Abstract: A printing head for flexographic printing on thin-walled objects not exhibiting a perfectly smooth surface, the printing head comprising an inking roller, which rotates on contact with a flexographic printing plate borne on a printing plate bearing roller, in which the printing head comprises a roller bearing a transfer surface which rotates on coming into contact with the printing plate, the transfer surface being a perfectly smooth and faultless surface and being made of a material that is more yielding than a material of which the flexographic printing plate is made.

Abstract: A rotary printing machine for printing on containers, comprising a chuck-bearing carousel exhibiting an intermittent circular motion, being rotatably supported by a base element or casing, and being powered by an electric motor and integrated encoder, in which the electric motor comprises a stator coil supported by the casing and a rotor supported directly by the carousel.
