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 device for transferring objects from a printing machine chuck to a support and distancing pin, the chuck and the pin being moved on two independent paths, at a point of which paths they are parallel to one another and at a predetermined reciprocal distance, the device comprising a carriage which is mobile in a parallel direction to the chuck and to the pin, between a distant position from the chuck and the pin to a close position to the chuck and the pin, means for gripping and releasing the objects being provided on the carriage, which means for gripping and releasing are mobile along a trajectory in a perpendicular plane to the carriage in order to be placed alternatively in front of the chuck and the pin, the trajectory including at least a tract in which it is parallel to the path of the pins.

Abstract: A printing machine for cylindrical objects, comprising a carousel for moving for locating the cylindrical objects in a successive number of work stations, among which at least a printing station and a drying station; at least a device for inking for printing on the lateral surface of a cylindrical object located in the printing station; and at least a drying device for generating a beam of rays which strike a cylindrical object located in the drying station; the drying device including an obturator for intercepting the beam of rays when the means for moving transfer the objects from one station to another.

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.
