Abstract: A printing machine comprising advancement elements for advancing material in sheet form to be printed which are provided at least with a traction drum which is designed to receive, at an entry region, the material in sheet form to be printed and to convey it toward an exit region spaced circumferentially apart, along the direction of rotation of the traction drum about its own axis, from the entry region; analog print stations are arranged around the traction drum, between the entry region and the exit region and, between at least two analog print stations, conveyance means are provided for conveying the material in sheet form to be printed which arrives from the traction drum along an advancement path that has at least one advancement portion for advancing the material in sheet form to be printed which extends substantially straight, along which at least one digital print station is arranged.

Abstract: A machine for digital printing on tape, which comprises a frame that supports elements of entraining at least one tape along an advancement path and is provided with at least one printing assembly, which comprises at least one ink-jet printing head; downstream of the printing assembly, along the advancement direction of the tape, there is at least one assembly for drying the inks applied to the tape; the drying assembly comprises a temperature-adjustable drum for supporting and entraining the tape, adhesion elements adapted to allow the retention in adhesion of the tape on the outer lateral surface of the drum, and hot air emitter elements which face at least one portion of the outer lateral surface of the drum.

Abstract: A machine for manufacturing printed laminated films, particularly for packaging, which comprises a frame that supports elements of traction of at least one primary film along an advancement path and elements of printing the primary film which are interposed along the advancement path. On the frame there are, in mutual succession, downstream of the printing elements, along the advancement direction of the primary film, elements of laminating a secondary film to the primary film with the interposition of an adhesive material and elements of electron beam polymerization of the adhesive material.

Abstract: A rotary printing machine comprising two supporting shoulders, a central drum or cylinder being rotatably mounted on the supporting shoulders, at least one printing unit being arranged around the drum and comprising a printing plate cylinder and an anilox roller, which are rotatably mounted on a respective pair of supporting elements and whose rotation axis is parallel to the axis of the drum, wherein at least the central drum is actuated by a source of motion which directly engages an axial shank of the drum.

Abstract: A flexographic rotary printing machine has a supporting structure provided with two lateral shoulders, an impression roller over which a material in sheet form to be printed passes, at least one printing element or assembly arranged adjacent to the impression roller and having an inking unit, a printing plate cylinder and an anilox roller, which are sleeve cylinders, and a drive for transmitting motion between the impression roller and each printing assembly. At each shoulder there is at least one lateral support device for the advancement-retraction of the sleeve cylinders, adapted to move them between a retracted or resting position, in which a respective sleeve can be inserted or removed, and an advanced or active position, in which the cylinders are kept in contact with, and operatively connected to, the impression roller.

Abstract: A rotary printing machine (1) comprising two supporting shoulders (3,4), a central drum (2) or cylinder being rotatably mounted on the supporting shoulders, at least one printing unit (11) being arranged around the drum and comprising a printing plate cylinder (30) and an anilox roller (8), which are rotatably mounted on a respective pair of supporting elements and whose rotation axis is parallel to the axis of the drum, wherein at least the central drum is actuated by a source of motion (6) which directly engages an axial shank (9a) of the drum.

Abstract: A machine for printing or spreading primers or coatings and the like with direct and indirect rotogravure system, comprising one or more printing or color units, with a respective drying hood and control unit, each printing or color unit comprising an orientatable inlet roller for tape material, a plurality of free rollers for conveying the tape material, an upper pressure roller, provided with a rubber sleeve, a lower pressure roller, a doctor blade, and an engraved cylinder. At least one roller, chosen between the upper pressure roller and the lower pressure roller, is rotated by a respective step motor and recirculating ballscrews and is supported on linear guides at its ends, with interposed pressure detecting means arranged to forward to the control unit signals indicating the linear pressure between the upper pressure roller and the lower pressure roller and the engraved cylinder.
