Abstract: A sheet processing machine has at least one shaping device and at least one sheet delivery unit, arranged downstream of the at least one shaping device along a transport path provided for a transport of sheets. The at least one shaping device has at least one shaping point which is formed by at least one forme cylinder, on one hand, and at least one impression cylinder, on the other hand. At least one separation device, for removing scrap pieces from sheets, is arranged downstream of the at least one shaping point along the transport path provided for the transport of sheets. The at least one separation device has at least one separation transport device. At least one transport device, configured as a selective transport device, is arranged following the at least one separation transport device along the transport path provided for the transport of sheets. The transport device is configured as at least one upper suction transport device for a hanging transport of sheets.

Abstract: A printing machine includes a printing assembly and a dryer unit having a dryer, with the dryer having at least one first energy output device. The at least one first energy output device is arranged such that it can be moved over an actuating distance between at least one active position and at least one stop position. The actuating distance extends in a continuously linear manner in or opposite to an actuating direction over at least 75% of its entire length. The actuating direction deviates by a maximum of 40° from at least one horizontal direction. The actuating direction deviates by a maximum of 40° from a normal direction of an average surface normal of an entire section, located in an active region of the at least one first energy device, of a transport path which is provided for a web-type printing machine. A method of operating a printing machine is also disclosed.

Abstract: A printing press has a printing unit with a print head, which is configured as an ink jet printing head, and a printing material guiding element which can be rotated about a respective rotational axis. The print can be moved along an actuating path in an actuating direction. The actuating direction has a component which is oriented orthogonally to an axial defined by the rotational axis of the printing material guiding element. A threading assembly, for threading in a printing material web along a threading path, is arranged within the printing unit. Parts of the threading path are spaced at least two centimeters from the axial direction in relation to every target region of every nozzle of every printing head of the printing unit. A method for threading a printing material web into the printing unit utilizes the threading assembly.

Abstract: A printing machine has a printing unit which has a printing-material conducting element that can be rotated about an axis of rotation defining an axial direction and at least four printing heads. Four positioning devices are arranged, by the use of each of which, at least one printing head can be arranged at least either in a respective printing position associated with the printing head or in a respective idle position associated with a printing head. At least one first printing head of the printing heads can be arranged either in a first printing position associated with that first printing head or in a first idle position associated with that first printing head. At least one second printing head of the printing heads can be arranged at least either in a second printing position associated with that second printing head or in a second idle position associated with that second printing head.

Abstract: A printing press has a printing unit which has at least one print head, which is configured as an ink jet printing head, and at least one printing material guiding element which can be rotated about a respective rotational axis. The at least one print head is configured so that it can be moved along an actuating path in at least one actuating direction. The actuating direction has at least one component which is oriented orthogonally with respect to an axial direction which is fixed by the rotational axis of the at least one printing material guiding element. At least one threading assembly for threading in a printing material web, which is movable along at least one threading path, is arranged or can be arranged at least temporarily at least within a printing unit. At least parts of the at least one threading path are at a spacing of at least two centimeters from the axial direction in relation to every target region of every nozzle of every printing head of the printing unit.
