Abstract: Flexographic printing machine consisting of one or more printing stations (100) situated in series, each printing station (100) comprising a frame on which at least one cliché-holder cylinder (102) is assembled, suitable for applying ink, taken from a tank (104) by means of at least one inking cylinder (106) in contact with the cliché-holder (102) and rotating in an opposite direction with respect to this, on a continuous strip (108) of materials to be printed. The strip (108) is moved and kept in contact with the cliché-holder cylinder (102) by means of at least one counter-drum (110) which rotates in an opposite direction with respect to the cliché-holder cylinder (102). In correspondence with the counter-drum (110) downstream with respect to the cliché-holder cylinder (102), there are one or more devices (112) capable of drying, desiccating, polymerizing and/or heating the ink deposited on the strip (108) by the cliché-holder cylinder (102).

Abstract: A device (2) is described for separating and conveying towards a packaging station (5) a predetermined number of flat objects fed in piles (13. 13?) by a folding unit (1). The device (2) comprises: a conveying surface (20, 120) provided with a plurality of slots (21), a plurality of shoes or carriages (24) which support a plurality of racks (31) moveable from a lowered position to a raised position in which the prongs (32) of the racks pass through the slots (21) of the conveying surface (20, 120) to protrude upward therefrom. A predetermined number of flat objects are separated from a pile (13, 13?) being formed to form a pack (113, 113?) between a pair of racks (31) supported by a pair of carriages (24), which are made to translate so as to convey the pack (113, 113?) towards the packaging station (5).

Abstract: A method and a device for cleaning a cylinder of a printing press—in particular of a flexographic printing press—are described wherein a layer of ink to be transferred to a web substrate to be printed—such as paper, plastic film and the like—is deposited on said cylinder (1) and wherein a fluid suitable to detach impurities from the area concerned is sent onto the surface of the cylinder (1) to be cleaned and a suction is provided to remove said impurities from the cylinder surface, said cleaning fluid being vapour.

Abstract: The invention concerns a plane die-cutting machine for die-cutting laminar material, of the type comprising a plane punch and an arc-shaped counter punch, which is controlled by moving means pressing the same against a work material inserted between it and the punch, said counter punch being simultaneously rotated around a line of instant-contact which runs along the punch. To avoid impacts between the reciprocally moving parts, the invention provides extensions integral to the punch and to the counter-punch, which maintain the contact between these latter for a portion of the reciprocal oscillatory movement outside the die-cutting area, so that said reciprocal oscillatory movement takes place with constantly contacting zones, like a blotter of blotting-paper.

Abstract: To ensure a uniform formation in packets with a predetermined number of elements, of sheet-like elements, for example, paper handkerchieves, two counter-rotating bodies are provided, presenting movable blades which, cooperate to receive each sheet-like element coming from a feeding group. Each pair of blades lays down a sheet-like element on a packet to be formed, on its turn supported by fins carried by belts or chains vertically moving downward, starting from the counter-rotating bodies and synchronically with the latter, in such a way that the packet to be formed lowers until the desired number of elements is received, and it is then ejected parallel to the axes of the rotating bodies.

Abstract: A plane die-cutting machine, having a plane and fixed punch as well as a counter-punch with arch-shaped profile and apparatus to roll the counter-punch without any reciprocal sliding with respect to the punch, in order to die-cut each sheet of material under work in succession by the displacement of the theoretical line of contact of the counter-punch on the punch.
