摘要： A device for drawing and bending the trailing edge of a printing plate onto a plate cylinder of a printing machine such as a sheet-fed rotary printing press, in which a pressure roller with an attached actuatable folding strip draws a printing plate, which has its leading print edge fastened into a tension rail, around the outer circumference of the plate cylinder as the plate cylinder is rotated, to a position where the folding strip is actuated thereby introducing the trailing edge of the printing plate into a second tension rail. The device provides a means for drawing the printing plate onto the printing cylinder with a desirable uniform tension and without requiring auxiliary devices for pre-folding the printing plate in order to secure the trailing printing plate edge into a tension rail.

摘要： An apparatus for the automatic changing of new and used printing plates in sheet-fed offset printing machines, having a plurality of printing units, includes a central printing plate storage container and a printing plate transport apparatus. Mounted on each plate cylinder of a printing unit is a guide device which is pivotable so as to be capable of being thrown onto the plate cylinder and off from the latter and via which a new printing plate can be fed from above to the plate cylinder and, with the plate cylinder slowly rotating backwards, a used printing plate can also be conveyed out and upwards. Mounted above the printing machine is a guide rail on which a travelling carriage of the transport apparatus, having plate gripping and lifting devices, can be moved along all the printing units of the printing machine. The transport apparatus conveys the used printing plates from the printing units to the central printing plate storage container and, from the latter, new printing plates are provided to the respective printing units, where these printing plates are fed to the plate cylinder via the gripping and lifting device and via the respective thrown-on guide device.

摘要： A device for introducing printing plates more simply into the opened gripping region of a tension rail assigned to the print start of a plate cylinder. The device includes an introduction rail extending over the format width of the plate cylinder and adapted to be moved against the outer circumference of the plate cylinder into a specific angular position in the region of the print start. When the introduction rail is so positioned, the front edge of the printing plate may be introduced directly into the gripping region of the print-start tension rail via an introduction face formed on the introduction rail. The outer circumference of the plate cylinder coacts with the introduction face of the introduction rail to define a funnel-shaped region for receiving the front edge of the printing plate just prior to the latter being inserted into the tension rail.

摘要： A clamping and tensioning rail for the trailing edge of a printing plate is mounted in the cylinder channel of a plate cylinder such that the trailing edge of the printing plate can be introduced in a simple way, without folding, into the gap between an upper and a lower clamping part. The clamping and tensioning rail is mounted pivotably about two pivot axes which are formed, for example, from stops fixed relatively to the cylinder and which interact respectively with an edge and an arcuate recess on the clamping and tensioning rail. Preferably, the clamping and tensioning rail is drawn into a completely open position by the force of a prestressed compression spring and can be pivoted against this force by an actuating shaft via lever arms and straps.

摘要： A chain operated sheet transport and transfer mechanism for sheet-fed printing machines having a plurality of printing units. The chain operated mechanism includes a plurality of gripper cars affixed to chains for movement between the printing units. The gripper cars each have a gripper impact strip and a pivotable gripper finger, with the gripper strip of each car extending the width of the gripper car and being of concave configuration. A bending device at the transfer zone of each printing unit is operable for acting on the gripper car to bend the concave gripper impact strips straight in order that sheets are transferred from one printing unit to the other without register deviation.

摘要： The invention relates to an apparatus for the metering of liquid media, especially varnish, of differing viscosity in an offset printing machine. Exchangeable metering subassemblies are assigned to a form cylinder. The first metering subassembly provided for processing low-viscosity media consists of a reservoir, a dipping roller, a metering roller and the form cylinder. The second metering subassembly for processing higher-viscosity media consists of a chamber doctor, a screened applicator roller and the form cylinder. In a further version, both metering subassemblies are assigned permanently to the form cylinder. Depending on the media to be processed, the necessary subassemblies are engaged with the form cylinder and the other subassembly is disengaged from the form cylinder.

摘要： A method and apparatus for washing printing press form cylinders and associated applicator rollers in a manner which reduces the drying of quick-drying media, such as varnish or ink, on the applicator roller and form cylinder. The washing device is disposed in a nip between the form cylinder and applicator roller and has two curved surfaces disposed in closely adjacent relation to respective surfaces of the form cylinder and applicator roller. Each curved surface has a spray device for directing a cleaning fluid onto the adjacent form cylinder and applicator roller and a suction-extraction device for removing sprayed cleaning fluid and removed ink and impurities. The method and apparatus may be selectively operated in a print-on mode in which a cleaning fluid is sprayed onto the rotating form cylinder and is suction-extracted from its outer surface. When printing is switched off, the method and apparatus may be operated in a print-off mode in which cleaning fluid is sprayed onto the rotating applicator roller and onto the rotating form cylinder, with the applicator roller is separated from the form cylinder.
