Examples relate to a device including an application unit having a first roller and second roller forming, in a nip thereof, a first roller gap through which powdered material can be conveyed to form a dry film. A counter-pressure roller together with the second roller, or a further roller downstream from the second roller, forms a second roller gap. A substrate path leads through the second roller gap for guiding a carrier substrate web through the second gap for applying the dry film thereto. At least one drawing device including a drive means for adjusting the first or second roller gap between two adjacent rollers that are movable relative to one another is provided on each frame side, enabling the two rollers to be moved toward one another in an adjustment direction, or be tensioned, and to be moved away from one another again, or at least be relaxed.

Examples relate to a sheet-fed rotary printing machine including a coating unit, which includes an impression cylinder and a further cylinder forming a contact zone therewith. The coating unit comprises a charging device for electrostatically fixing sheets on the impression cylinder, which includes an electrode unit that is directed toward the outer cylindrical surface of the impression cylinder. A charging core zone includes a region of an outer cylinder surface of the impression cylinder that is located next to the electrode unit. The charging core zone is arranged downstream from the contact zone and upstream from a transfer point leading away from the impression cylinder. An electrode of the electrode unit has a minimum first distance with respect to the impression cylinder of between 4 mm and 13 mm and a minimum second distance with respect to the further cylinder of between 4 mm and n 35 mm.

Examples relate to a device including a first application unit having a first roller and second roller forming, in a nip between the outer cylindrical surfaces thereof, a first gap through which powdered material can be conveyed to form a first dry film. The second roller, or a further roller following downstream from the second roller, together with a counter-pressure roller forms a second gap through which a carrier substrate is guided to have the dry film applied. The first and the second rollers can be inclined with respect to one another based on a relative progression of axes of rotation thereof and can be varied in relative inclinations. The first or second roller is mounted in the device to be pivotable about an actual or imaginary pivot axis which extends perpendicular to the axis of rotation of the pivotable roller and/or of the other of the two rollers.

Examples include a sheet processing machine to which a transport path is assigned for transporting sheets. The sheet processing machine includes an application device with an application point for applying material to the sheets. A cooling device including a cooling cylinder is arranged along the transport path, downstream from the application point. An inspection transport body is arranged along the transport path, downstream from the cooling cylinder, and has a sensor device of an inspection unit aligned therewith. Examples further include a sheet-fed printing machine with a simultaneous double printing unit and an application point. A curing device with an LED UV radiation source is arranged downstream from the application point and includes two curing units for drying two opposite sides of sheets. A cooling device of the curing device includes a cooling element with a line system, and the cooling section is arranged downstream from the curing section.

Examples include a device for aligning magnetic or magnetizable particles contained in a coating agent applied to one side of a web-format or sheet-format substrate. An alignment device comprises one or more magnetic elements that, during normal operation, are fixed to a frame at the transport path and, in a working position, enter into magnetic interaction with magnetic or magnetizable particles on the substrate guided past the device along the transport path. The one or more magnetic elements are arranged at a carrier that extends transversely to the transport direction over a working width provided for processing the substrate. The carrier is mounted, on both sides, in or at a respective guide and can be moved in or at the guide, together with the one or more magnetic elements, along a movement path from the working position into a makeready position.

Examples include a cylinder having a holding means around the circumference and by which a substrate sheet can be picked up and held during rotation of the cylinder over a rotation angle range between when the substrate sheet is received and is transferred downstream. A rotary union includes a rotor rotating along with the cylinder which, at an end face, is arranged with a stator that does not rotate during regular operation. A vacuum pressure can be applied via the rotary union to suction openings provided around the circumference of the cylinder while running through an active rotation angle phase of the cylinder. The rotary union can be set in terms of a size of a passage angle sector determining the size of the active rotation angle phase and/or in terms of a position of the passage angle sector determining the position of the active rotation angle phase.

Examples include a pile cutting apparatus including a cutting device for cutting a sheet pile, with a front pile bearing surface, a rear pile bearing surface, and a cutting gap arranged therebetween. A table plane contains the front pile bearing surface. The cutting device further includes a movable upper blade, a lower blade including a cutting edge, and a cutting aid for fixing sheet piles that is upstream from the upper blade along a transport path for transporting sheet piles. A movable support element has a contact surface for supporting sheets and is movable between a support position and a disposal position. The contact surface, when the support element is arranged in the support position, is arranged in and/or beneath the table plane, and is closer to the cutting edge when the support element is in the support position than when the support element is in the disposal position.

Examples include activating at least one alignment segment of a processing machine. The at least one alignment segment is arranged before at least one processing unit of the processing machine that is activated. The at least one alignment segment includes a plurality of transport sections following one another in the transport direction. At least two transport sections, following one another in the transport direction, each have a basic position and at least one adjustment position. The at least one adjustment position in each case is offset relative to the basic position in the transverse direction. At least one transport section of the transport sections is axially adjusted. At least one dedicated drive axially adjusts the at least one transport section of the transport sections, and the at least one dedicated drive is designed as a direct drive.

Additionally, suction elements with suction openings pointing outwards are also arranged in the circumferential region. A plurality or all of the magnetic elements are arranged one behind the other and are each combined with at least one assigned suction element in respective modular units as action units in a plurality or all of the columns of magnetic elements. The action units can be positioned in each case independently of the other action units in the circumferential direction and/or can be detached from the cylinder.
