摘要： A gravure printing unit is usable for printing onto substrate according to a gravure printing method. The gravure printing unit has a forme cylinder, which comprises, on its circumference, an image-forming pattern of recesses, and has an inking unit for inking the pattern of recesses provided on the forme cylinder. The inking unit comprises a first inking unit cylinder, which comprises recesses in a region of its outer cylindrical surface that correspond to the recesses on the forme cylinder, and which form a nip point downstream with a second inking unit cylinder, which comprises, on its circumference, ink-transferring elevations or raised areas. The recesses are formed on the outer cylindrical surface of an ink transfer forme sheath. The first inking unit comprises a cylinder body which is or which can be mounted rotatably in the inking unit and on which a circumferentially closed ink transfer forme sheath, that carries the recesses of the first inking unit cylinder on its outwardly facing surface, is or can be detachably arranged. A printing press has such a gravure inking unit. A setting up method, an ink transfer forme sheath, and a method for producing the same are also disclosed.

摘要： A jacket-securing arrangement is disclosed for mounting in a cylinder, which cylinder (220) has an outer surface and at least one recess (320) in the outer surface for receiving an inwardly turned edge of a replaceable jacket (225) overlying at least part of the outer surface of the cylinder. The jacket-securing arrangement is mountable within the recess so as not to project beyond the outer surface of the cylinder when the jacket is secured thereto, and includes a clamping lever pivotable about a shaft located within the recess between a clamping position in which the edge of the replaceable jacket is clamped between the lever and a side wall of the recess and a release position in which the lever is spaced from the side wall of the recess. A magnet is provided to retain the lever in the clamping position. The clamping lever is formed of two or more members assembled around the shaft and defining between them a bearing surface engaging an outer surface of the shaft. The shaft may be a gripper shaft including a plurality of grippers for securing a printing substrate sheet to the outer surface of a substrate transport cylinder of a printing system, the jacket-securing arrangement being disposed between grippers.

摘要： A cylinder is arranged to receive one or more hollow cylinders on an outer surface of the cylinder. The cylinder has at least one movable stop with at least one movable element. In an idle position the at least one movable element does not protrude beyond the outer surface of the cylinder and allows hollow cylinders to be slid over the cylinder, and in an active position it protrudes beyond the outer surface of the cylinder and acts as a mechanical stop for hollow cylinders. The at least one movable element can be moved from the idle position to the active position, and vice versa, by means of a rotary movement. A method for positioning a hollow cylinder on a cylinder of this kind.

摘要： A device for treating substrates has a separation system, with which processed substrates can be separated into one or more waste parts and at least one blank. The device for treating substrates offers improved flexibility. The separation system comprises a transport cylinder and a stripping cylinder associated therewith. The transport cylinder is able to secure replaceable packing, along with first and second openings which, when the packing is secured, are covered at least partially by perforations that may be formed in the packing. A first air supply supplies air to the first openings and a second air supply supplies air to the second openings independently of the supply of the air to the first openings. The first and the second air supply are switchable between a suction air supply and a blower air supply.

摘要： A device and method are described for the easy and rapid loading and unloading of flexographic sleeves from flexographic processing machines. The device includes internal chucks that hold on to the end of a sleeve or sleeve adapter. The chucks are rotatably mounted within a flexographic processing machine to permit sleeve processing. In addition, the chucks may move to accommodate a large range of sleeve or adapter diameters and lengths. The method permits the loading and unloading of sleeves with a minimum amount of sleeve handling and without additional end pieces or adapters.

摘要： An adapter sleeve has an external layer for supporting a printing cylinder carrying data and/or images to be printed. The adapter sleeve has an internal layer defining a bore enabling the sleeve to be mounted onto a rotary mandrel of a printing machine. Each opposite extreme end of the adapter sleeve includes a rigid, load-bearing, radial spacer member disposed between the layers to provide rigidity and indeformability during the use of the sleeve with time. The inner surface of each of the extreme end radial spacer members is defined by rigid and non-deformable material of very low coefficients of dynamic and static friction.

摘要： A method for registering a printing plate includes supporting the printing plate on a support surface. A plurality of registration members adapted to register an edge of the printing plate is provided. The first printing plate is moved over the support surface along a first direction to a position where the edge of the printing plate contacts a first registration member of the plurality of registration members. The first registration member is moved along a second direction that intersects the first direction while maintaining contact between the first registration member and the edge of the printing plate at a location on the edge that does not substantially vary as the first registration member moves along the second direction. Contact is established between the printing plate and a second registration member of the plurality of registration members after the first registration member has commenced moving along the second direction.
