Abstract: In some examples, a transport cylinder for transporting a sheet-format substrate includes at least one channel extending on an outer surface of the transport cylinder in an axial direction. Each channel includes at least one gripper, which is supported on a shaft, for holding a substrate on the outer surface of the transport cylinder. Each channel is covered by a respective cover at the outer surface of the transport cylinder. The cover and/or a shaft supporting the at least one gripper may include a cooling unit. In some examples, a drying unit that includes the transport cylinder may further include an electron beam for curing a printing fluid on a substrate on the transport cylinder. In some examples, a printing press may include the drying unit including the transport cylinder.

Abstract: There is described an intaglio printing press (1; 1*) comprising a plate cylinder (8) carrying one or more intaglio printing plates, the plate cylinder (8) receiving ink from an inking system (9, 20, 23; 20*, 23*) having a plurality of chablon cylinders (23; 23*) transferring ink directly or indirectly onto the plate cylinder (8), the intaglio printing press (1; 1*) comprising an adjustment system acting on the chablon cylinders (23; 23*) in order to compensate elongation of the one or more intaglio printing plates. The adjustment system comprises, for each chablon cylinder (23; 23*), an adjustable drive unit, which adjustable drive unit (25) is interposed between the chablon cylinder (23; 23*) acting as a rotating output body of the adjustable drive unit (25) and a driving gear (100) acting as a rotating input body of the adjustable drive unit (25).

Abstract: There is described an intaglio printing press (1; 1*) comprising an intaglio cylinder (8) and an ink wiping system (10) with a rotating wiping roller assembly (11) contacting a circumference of the intaglio cylinder (8) for wiping excess ink from the surface of the intaglio cylinder (8), a rotational speed of the wiping cylinder being adjustable with respect to a rotational speed of the intaglio cylinder (8). The intaglio printing press (1; 1*) comprises an adjustable drive unit (25), which adjustable drive unit (25) is interposed between the wiping roller assembly (11) acting as a rotating output body of the adjustable drive unit (25) and a driving gear (100) coupled to the intaglio cylinder (8) and acting as a rotating input body of the adjustable drive unit (25). The adjustable drive unit (25) is designed to allow selected adjustment of a rotational speed of the wiping roller assembly (11) with respect to a rotational speed of the driving gear (100).

Abstract: There is described an ink wiping system (100; 100?; 100?) of an intaglio printing press comprising a wiping tank (101) and a rotatable wiping roller assembly (102; 102*) supported on and partly located in the wiping tank (101) for wiping excess ink from the surface of a rotatable intaglio printing cylinder (80) of the intaglio printing press. The ink wiping system (100; 100?; 100?) comprises a wiping roller retracting device (150) which forms an integral part of the ink wiping system (100; 100?; 100?) and is adapted to be coupled to the wiping roller assembly (102; 102*) to move the wiping roller assembly (102; 102*) between a working position (W) where the wiping roller assembly (102; 102*) is supported on and partly located in the wiping tank (101) for cooperation with the intaglio printing cylinder (80) and a parking position (P) where the wiping roller assembly (102; 102*) is retracted out of the wiping tank (101) and away from the intaglio printing cylinder (80).

Abstract: A gravure printing press utilizes a printing assembly with a printing forme cylinder that is twice as large in relation to the number of multiple copies which can be printed during one revolution. The printing forme cylinder, in a thrown-on position, forms a printing point with an impression cylinder which is twice as large in relation to the number of multiple copies which can be printed during one revolution. A wiping cylinder, in a thrown-on position, also interacts with the printing forme cylinder. An ink collecting cylinder, in its thrown-on position, interacts with the printing forme cylinder. A plurality of stencil cylinders, in thrown-on positions, interact, one after another, with the ink collecting cylinder on the circumference thereof. Each of the stencil cylinders can be inked by at least one inking unit. The ink collecting cylinder is configured with a circumference which is larger than the printing forme cylinder by an integral multiple.
