A sheet-fed printing machine contains a printing unit, a drier, and a sheet handling device for transporting or guiding print sheets. The sheet handling device has an opening disposed downstream of the drier in the direction of transport. A humidification device for rehumidifying the print sheets is disposed in such a way that it rehumidifies the print sheets through the opening. The sheet handling device may contain a guide plate or several guide plates.

A sheet-fed printing unit has a first impression cylinder and a second impression cylinder, which are arranged directly and interactingly in contact and which each have an axis of rotation. An axial plane contains the axes of rotation. A reference plane is a plane which contains an axis of rotation of a cylinder of this type and has a horizontal surface normal. These two cylinders are arranged such that an intersection angle between the axial plane and the reference plane is a maximum of 15. A transport path is provided for a transportation of sheets, which transport path has a region for the respective impression cylinder in which there is contact between sheets and a casing surface. This region of the transport path for the respective impression cylinder extends over an angular range of at least 270. A sheet-fed printing machine has a sheet-fed printing unit of this type.

A sheet-fed printing machine comprises two sheet-fed printing units; of which a first is configured as a sheet-fed simultaneous printing unit and has two collector cylinders, which interact with one another and each have an axis of rotation. An axial plane contains the axes of rotation of the collector cylinders. A reference plane contains an axis of rotation of this type and has a horizontal surface normal. An intersection angle between the axial plane and the reference plane is, at a maximum, 45 degrees. A first one of the sheet-fed simultaneous printing units has exactly four plate cylinders, of which exactly two are arranged such that they directly interact with the first collector cylinder and has exactly two others which are arranged such that they directly interact with the second collector cylinder. A second sheet-fed printing unit has at least one impression cylinder and at least one plate cylinder, which is arranged such that it directly interacts with the impression cylinder and which is configured a screen printing plate cylinder, or as a flexo plate cylinder or as a numbering plate cylinder. The two collector cylinders of the first printing unit and the impression cylinder of the second printing unit have the same circumference.

In an example, a clamp may include a roller disposed on a swingarm, a slide disposed on the swingarm that may apply friction against the roller in a first position and in a second position, a cam to engage with the slide, and a latch to retain the slide in the second position. The slide may move from the first position to the second position as the slide moves along the cam, and the slide may apply a greater friction against the roller in the second position than in the first position.

A device is provided for aligning magnetic or magnetizable particles, which are contained in a coating that is applied to a first side of a web-type or a sheet-type substrate. An application device is arranged in the transport path of the substrate, by the use of which, the coating is applied or is applicable to the first side of the substrate, in at least one application site. A first cylinder, which is embodied as a magnetic cylinder, is arranged in the transport path of the substrate to be transported downstream of the application device and comprises a plurality of elements creating a magnetic field in the region of the outer periphery of the first cylinder. Another cylinder, which is embodied as a magnetic cylinder, is arranged in the transport path of the substrate to be transported and comprises a plurality of elements creating a magnetic field in the region of the outer periphery of that cylinder. A drying device or an hardening device is arranged on the transport path between a site of a winding-on of the substrate on the first cylinder and a site of a winding-on of the other cylinder. The first cylinder, which is embodied as the magnetic cylinder, is arranged in the transport path of the substrate to be transported on the second side thereof. The drying or the hardening device is oriented in the transport path of the substrate to be transported on the first side thereof.

The invention relates to a sheet-fed printing press having a feeder, a delivery, and at least one sheet guiding cylinder, which is arranged between the feeder and the delivery, has a gripper system, and is assigned a digital printing system and a first sheet guiding system that removes sheets from the sheet guiding cylinder. The object of the invention is to devise a sheet-fed printing press that can be used in a more variable fashion, and with which a particularly wide spectrum of different products can be produced. According to the invention, the object is attained in that the first sheet guiding system (12) is configured for selectively transferring the sheets to a second sheet guiding system (8), which transfers the sheets to the sheet guiding cylinder (3), or for transferring said sheets to the delivery (11), wherein the second sheet guiding system (8) is configured as a perfecting system (8) and can be switched between an operating mode in which it feeds the sheets in a reversed position to the sheet guiding cylinder (3) and an operating mode in which it feeds the sheets in a non-reversed position to the sheet guiding cylinder.

In one example, a system can include a media pathway to transport a media into a stacking region, a clamp pathway to move a clamp along the clamp pathway, and a registration surface. The registration surface may be positioned between an edge of the media pathway and the clamp pathway.

A precision positioning device of a unit-type die cutting & hot stamping machine includes a positioning element on an input end of a first imprinting element and a positioning element on an output end of each imprinting element. Two neighboring positioning elements accomplish the positioning between the two positioning elements together. Each positioning element is constituted by a positioning assembly installed symmetrically on each end of the imprinting element. The positioning assembly includes a positioning rod which can rotate against an installation shaft. Each positioning rod includes a positioning block which is provided with a reference surface. A rear side of the gripper is provided with a reference matching surface. By the positioning elements, the accuracy in the art of die cutting & hot stamping can be assured when the machine is performing a multiple-working-position procedure.
