Abstract: An apparatus and method for cleaning guide rollers of a printing unit, particularly a 9-cylinder satellite printing unit, of a web-fed printing press, is disclosed. A cleaning device having a cleaning body fastened to an actuating grip is insertable between the guide rollers of the printing unit. A cleaning cloth that can be wetted with cleaning fluid can be fastened to the cleaning body, and the cleaning body features cleaning surfaces on opposing sides that are adapted to the contour of the guide rollers.

Abstract: A device and method for performing a printing plate change on a plate cylinder of a printing press is disclosed. The device includes a rolling element featuring several rollers for pressing at least one printing plate on the plate cylinder during a printing plate change. A strip bearing several alignment elements extends parallel to the rolling element, where a printing plate can be aligned true-to-register between every two adjacent alignment elements before the printing plate is clamped in a lockup slot of the plate cylinder.

Abstract: A web-fed press includes at least two printing units and at least one drier for drying at least one printing-material web which is moved through the at least two printing units and printed on at least one side with at least one offset printing ink at each of the printing units. The printing-material web is dried at least after the first printing unit and before the second printing unit.

Abstract: A printing unit of a web-fed rotary printing press with several printing couples is disclosed. Each printing couple features a transfer cylinder, a plate cylinder, an inking couple and preferably a dampening unit, where the transfer cylinder and the plate cylinder of each printing couple are positioned jointly on side walls of a frame of the printing unit, and where the printing unit is aligned in the web-fed rotary printing press via bearing devices which engage on the frame of the printing unit. Rollers of the inking couples and/or dampening units of the printing couples are positioned on separate supporting walls such that the supporting walls are displaceable with respect to the side walls on which the transfer cylinders and plate cylinders of the printing couples are positioned, in order to facilitate access to the cylinders and the rollers of the printing couples.

Abstract: A printing unit of a web-fed rotary printing press with several printing couples is disclosed. Each printing couple features a transfer cylinder, a plate cylinder, an inking couple and preferably a dampening unit, where the transfer cylinder, the plate cylinder, and rollers of the inking couple and if applicable of the dampening unit of each printing couple, are coupled on the drive side via gears and jointly positioned on side walls of the printing unit. Independently driven ink fountain rollers of the inking couples together with an ink fountain as well as a film roller of the inking couples are positioned on separate side walls in such a way that, in the region of each printing couple, the ink fountain roller, the ink fountain as well as the film roller of the respective inking couple are displaceable relative to the cylinders and rollers of the printing couples.

Abstract: A method and apparatus for handling printing plates on a web-fed printing press is disclosed. Printing plates imaged on an imaging device are assigned a coding relating to the plate cylinder position of the printing couple at which the respective printing plate is used. Imaged printing plates are inserted into cassettes such that printing plates for several printing couples are positioned in each cassette, where each cassette is assigned a data record relating to the position at which each printing plate is arranged within the respective cassette. The loaded cassettes are conveyed to the region of the printing couples where the data record assigned to the cassettes is also made available in the region of the printing couples. The printing plates are removed from the cassettes and, with a comparison to the data record assigned to the respective cassette, supplied to the respective printing couples.

Abstract: A printing unit of a web-fed printing press is disclosed. The printing unit includes four printing couples where each printing couple includes a plate cylinder, a transfer cylinder, an inking system as well as, if applicable, a dampening system. The transfer cylinders of every two printing couples arranged horizontally next to one another which form a printing couple group, form a nip, through which a to-be-printed printing substrate can be conveyed. The center points of the transfer cylinders (rolling off one another) of every printing couple group each lie on a horizontally running line. Two printing couple groups offset from one another in the vertical direction are also offset from one another in the horizontal direction such that the print positions as well as the center points of the transfer cylinders and the plate cylinders of the printing couple groups are offset from one another in the horizontal direction.

Abstract: A printing unit of a web-fed printing press having several printing couples is disclosed. Each printing couple includes a plate cylinder, a transfer cylinder, an inking system as well as, if applicable, a dampening system. Two printing couples respectively arranged vertically one above the other form a printing couple group and are assigned a common safety device in order to cover hazardous areas on the respective printing couple group. The safety device is translatorily displaceable at least in sections in order to free up or block access to the printing couples of the printing couple group.

A strip bearing several alignment elements extends parallel to the rolling element, where a printing plate can be aligned true-to-register between every two adjacent alignment elements before the printing plate is clamped in a lockup slot of the plate cylinder.

Abstract: A printing plate for a printing machine, more preferably for a reel-fed rotary printing machine, is disclosed. The plate has a plate-like main body serving as a subject carrier, with a leading end which is angled-off relative to the main body, and with a trailing end which is angled-off relative to the main body where the printing plate can be mounted or placed on a form cylinder of a printing machine via the leading end and the trailing end, and where the leading end and the trailing end are symmetrically angled-off relative to the main body such that the leading end and the trailing end enclose an approximately identical angle with one side of the main body. The leading end and the trailing end each enclose an angle between 85° and 90° with the side of the main body.

Abstract: A nine-cylinder satellite printing unit includes printing stations having a first, second, third and fourth transfer cylinder which a web passes through. The transfer cylinders are capable of being stopped when the printing assembly is switched off. A distance between each of the first and second transfer cylinders, the second and third transfer cylinders, and the third and fourth transfer cylinder is shorter than the distance between the first and fourth transfer cylinder. A guide roller keeps a supplied portion of the web away from the first transfer cylinder and another guide roller keeps a discharged portion web away from the fourth transfer cylinder when the first and fourth printing cylinders are respectively in print thrown-off positions.
