Abstract: The cartridge (1) for feeding ink to an ink duct of a printing machine comprises, for containing ink, a hollow casing (2) presenting a base (4) provided with an ink dispensing valve (4a) and a piston (5) slidable within the hollow casing (2) to cause the ink to be dispensed by the dispensing valve (4a). The piston (5) presents a non-return valve (7) for feeding ink into the hollow casing (2), to enable the cartridge to be recharged. The cartridge filling device (30) comprises a housing (32) for the cartridge (1) and a filling head (33) associable with the piston and supported by actuator means (34) for its movement. The head (33) is connected to an ink feed pump (35) and presents at least one opening element (37) for opening the non-return valve (7) of the piston (5), to deliver ink into the cartridge (1).

Abstract: A device for feeding ink prepackaged in containers to the ink duct of printing machines includes a unit for holding the container and for dispensing the ink contained therein, where the unit included a base provided with at least one through aperture, an intermediate component and an operating head, in which the base, the intermediate component and optionally the operating head define, when in their operative position, a compartment for receiving the container, and in which the operating head includes a press operated by pressurized fluid to exert a pressure on the container ink to dispense it.

Abstract: This method for impregnating cleaning fabrics with detergent liquid has the characteristic of radially and centrifugally spraying a reel of fabric (11) through profiled apertures (3) present in a rotatable feed shaft (1), said shaft being internally filled with detergent liquid under pressure in accordance with selectively variable parameters, said liquid being fed into said rotatable feed shaft (1) by suitable pipes provided with rotary seals.

Abstract: This apparatus for the preparation and/or regeneration of detergent reels of fabric for cleaning printing cylinders or cylinders of similar precision has the characteristic of impregnating the fabric (4) by its immersed transit through a suitable container (10), and by a subsequent sinuous passage involving its pressing and folding in alternate directions by a plurality of rollers implementing uniform distribution of the detergent, said passage terminating with winding the fabric into a new reel (8) of collected fabric which, thus treated, has acquired and/or conserved properties suitable for its use.

Abstract: A device for cleaning the outer surface of rotary cylinders and the like (2) comprising a pair of rotatable members (9, 11) for unwinding and rewinding a fabric (10), a presser means (12) cooperating with the fabric (10), means (50) for feeding onto the fabric (10) a liquid for cleaning the cylinder (2), and means (51) for feeding drying air onto the rotary cylinder (2), in which the pair of rotatable members (9, 11), the presser means (12) and the detergent liquid feeding means pertain to a cleaning assembly (6) movable by pneumatic drive away from and towards the rotary cylinder (2).
