摘要： PROBLEM TO BE SOLVED: To allow a member for clamping and a body journal to be scarcely relatively rotated by providing a coupling member spring-elastically operating axially without play in a rotating direction between a clamping ring and a member tightly coupled to a sheet guide cylinder. SOLUTION: In a driving unit of the double gear, a tie rod 9 penetrating a main gear 4, gear flange 3 and clamping ring 7 is spring-elastically supported to the ring 7. The rod 9 is loaded by a lap leaf spring 10. The rod 9 is previously regulated to clamp a gear ring 5 at the gear 4. The rod 9 is released from a driving force of a circumferential direction by coupling to a coupling plate 16 without play. Since the plate 16 is relatively thin, it allows axial movement of the ring 7 by an elastic deformation. At the time of eliminating clamping of a separating coupler 11, relative positions among the ring 7, flange 3 and a body journal 1 are continuously the same.

摘要： PROBLEM TO BE SOLVED: To reduce the liberation of an ink and a varnish in a pile of discharged printed sheets of paper by a face printing or double-side printing by a method wherein a drying device is disposed in an opening of the guide surface of a printed sheet guide system as a module, and the drying device is functionally combined with an air cooling system which is a separate body. SOLUTION: When a sheet of paper 5 is printed on one surface, the printed sheet 5 is dried by a drying device 10 which is operating. The pneumatic system 13 of a printed sheet guide system 9 which is disposed so as to correspond, is switched to a suction operation, and a cooling system 15 circulates cooling medium. When a drying device 18 is started, simultaneously with the heat transfer of the drying device 10 to the printed surface of the printed sheet 5, the rear surface which is not printed, is heated by the drying device 18 as well. At this time, fortunately, the temperature difference between the face surface and the rear surface of the printed sheet 5 is extremely small, and for this reason, in a pile of discharged sheets, the transfer of an ink or a varnish to the rear surface due to a heat transfer path, becomes drastically less.

摘要： PROBLEM TO BE SOLVED: To improve a printing process by a method wherein a driving machine capable of adjusting a position is arranged to at least one cylinder in each printing unit, and a positional target value wherein a gear train between each two driving machines is strained by a specific angle value via a control machine can be supplied to the driving machine. SOLUTION: In order to achieve synchronous operation in printing operation according to a target value supplied to a driving machine AGZ of a rubber cylinder GZ, positional target values LS1 to LS4 are supplied to the driving machine APZ of a plate cylinder Z. For example, to the positional target value LS3 of a printing unit AGZ, an angle slippage likely to strain a gear train positioned between the second and third printing units by a specific angle value is supplied. Further, in relation to the positional target value LS3 of the driving machine AGZ of the rubber cylinder GZ in the third printing unit, an angular slippage of the positional target value LS4 for the driving machine AGZ of the rubber cylinder GZ in a fourth printing unit is supplied.

摘要： PROBLEM TO BE SOLVED: To provide a method for intaglio printing by which it is possible to avoid the use of an evaporable solvent or a harmful chemical for health when using an erasable and reusable intaglio printing plate, and further, simplify a methodological concept in this field as well as a device using this method. SOLUTION: Based on an intaglio printing master which undergoes a filling step for forming a printing plate and an image forming step following the former, the recessed part is uniformly filled with a UV printing ink by a feed device 2 and the UV printing ink is cured by a UV drier 3 in the filling step. Further, in an image forming step, the UV printing ink cured by thermal cutting 5 is removed from the recessed part, fashioned after an image and an intaglio printing plate to which a lustering process is applied based on the image is colored in the UV printing ink using a coloring system 7. For reuse, the intaglio printing plate passes through an erasure step using the UV printing ink.

摘要： PROBLEM TO BE SOLVED: To clean a surface of a printer cylinder, packing paper and a film, on which paper dust and stain like a solidified printing ink are fixed, by coating the surface of the printer cylinder with an aqueous alkaline cleaning agent and removing the cleaning agent with a cleaning liquid after the cleaning agent is made to act on the surface for a fixed time. SOLUTION: When an aqueous alkaline cleaning agent is supplied to a casing 12 and an ink attaching roller 9 is rotated, a large number of wells arranged on the outer face of the ink attaching roller 9 receive the cleaning agent from the casing 12 and convey a desired cleaning agent to a printer cylinder 5. At this time, the ink attaching roller 9 is attached with pressure to the cylinder 5, and the cylinder 5 is rotated. When the cleaning agent is completely supplied to the surface of the cylinder 5, a cleaning device 7 is cut off from the cylinder 5 and the cylinder 5 is stopped. The cleaning agent applied to the surface of the cylinder 5 forms a gel-like film on the surface of the cylinder 5. The film acts on the structurized surface of the cylinder 5 for a fixed time. After the acting time has passed, a cleaning device 6 is attached with pressure to the outer face of the cylinder 5 and the cleaning agent is washed away from the surface of the cylinder 5 with water.
