摘要： A coating head device for coating an engraved surface on a coating cylinder of a printing press having a main body with a longitudinal cavity for liquid, open to the coating cylinder and substantially sealable to the coating cylinder. The cavity has an injection zone providing for a zone pressurizing the liquid within a portion of said cavity in the main body to compel liquid into cells in the engraved surface of the coating cylinder. The main body has an inlet to provide liquid to the supply chamber and a return to exhaust liquid from the outlet section.

摘要： A cassette for a wedge-shaped ink well of a printing machine has a bottom and a rear wall and two side walls. A front of the cassette, opposite the rear wall, faces a duct roller of the printing machine when the cassette is inserted into the ink well and is open. A handle connected to the upper portions of the side walls is positioned such that the cassette tends to incline to prevent ink from flowing out of the front of the cassette when the cassette is handled outside of the printing machine. The bottom and the sides of the cassette are sealed against the ink well adjacent to the duct roller. A seating arrests movement of the cassette relative to the ink well when the cassette is inserted in the ink well thus ensuring that the duct roller uniformly inked between sides of the ink well.

摘要： An on demand ink mixing system for a flexographic or similar printer utilizes a chambered doctor blade with a chamber divided by a flexible bladder to form ink chamber and a pressure chamber. Ink use is coordinated with print run length, and ink mixing and the collapse of the ink chamber to essentially zero volume are coordinated to coincide with the end of the run. The flexible bladder is also utilized in the operation of the ink cleaning system to move cleaning solution through all portions of the supply system and printer contaminated by ink mixed for the run.

摘要： In an ink film thickness control method for an ink supply apparatus including an ink fountain for storing an ink, a plurality of ink fountain keys whose aperture ratios are independently adjusted to supply said ink in said ink fountain, an ink fountain roller to which said ink is supplied through said ink fountain keys, and an ink ductor roller for supplying said ink supplied to said ink fountain roller to a printing plate through an ink roller group in accordance with a feed operation, the feed operation of said ink ductor roller is set in an OFF state when said printing plate is to be exchanged. A printing press in which said previous printing plate is kept mounted is operated without performing the feed operation of said ink ductor roller, thereby rotating said ink roller group. Printing is performed on a predetermined number of paper sheets using said previous printing plate to leave a first minimum ink film thickness distribution necessary for printing such that an ink film becomes thinner from an upstream to a downstream.

摘要： The offset printing machine comprises at least one flexible ink blade (14) which, angled in the direction of an ink roller (12), borders an ink bath (40) and can be bent in zones to different degrees against the cylindrical surface of the ink roller (12), and adjustment means for bending the ink blade edge (36). The adjustment means has tappets (92) axially displaceable in a guide and an adjustment cam (62) allocated to each, with the cam axis (L) parallel to the ink roller axis (A). The tappets (92), preferably individually adjustable length-wise, are pressed by springs (100) against the peripheral surface (72) of the adjustment cam (62). The self-locking positionable adjustment cams (62) are arranged alternately in the modular principle with bearing jaws (64) for their non-rotatable coaxial bearing bolts (60) on a mounting rail (56), for interchargeable mounting as a control unit (58) directly or via an adapter on an offset printing machine. The peripheral surface (72) of the adjustment cam (62), produced with very high precision, lies freely in a longitudinal groove (89) of the control unit (58), and is progressively curved according to a further feature of the invention.

摘要： The invention relates to an apparatus for the metering of liquid media, especially varnish, of differing viscosity in an offset printing machine. Exchangeable metering subassemblies are assigned to a form cylinder. The first metering subassembly provided for processing low-viscosity media consists of a reservoir, a dipping roller, a metering roller and the form cylinder. The second metering subassembly for processing higher-viscosity media consists of a chamber doctor, a screened applicator roller and the form cylinder. In a further version, both metering subassemblies are assigned permanently to the form cylinder. Depending on the media to be processed, the necessary subassemblies are engaged with the form cylinder and the other subassembly is disengaged from the form cylinder.

摘要： A fountain assembly for applying a fluid composition uniformly to the circumferential surface of a rotating transfer roller. The assembly has an elongated plastic frame having a concave channel formed on one side of it and a rigid metal brace on the other side. A pair of doctor blades is attached to opposite sides of said channel and positioned to contact the surface of the transfer roller. A pair of curved radial surface seals form a resilient bulkhead with the ends of said doctor blades to form a seal with the roller. The radial surface seals, doctor blades and concave channel form a closed chamber when positioned against the transfer roller. A pivot supports the fountain assembly, alternately swiveling said fountain assembly toward and away from the transfer roller. Means are provided for supplying a fluid composition into the channel. In one embodiment, air cylinders are mounted between the pivoting support and frame for adjusting the position of said fountain assembly by thrusting the frame into and out of contact with the transfer roller. In another embodiment, washing nozzles are disposed along the channel for spraying a washing solution to the channel via an internal manifold within the frame for directing a washing fluid to the nozzles and dispensing a controlled amount of a washing solution under pressure through the manifold and nozzles.
