Abstract: A device for printing on hollow bodies has a plurality of printing units each having a printing cylinder. At least one of the printing units has an inking unit having a chambered doctor blade that provides printing ink. The chambered doctor blade system has at least one ink pan and a doctor blade holder in a single assembly. The single assembly of the chambered doctor blade system is retained in the inking unit only on one side. The assembly of the chambered doctor blade system forms a cantilever arm on a side frame of the inking unit. The assembly of the chambered doctor blade system can be moved axially parallel to the anilox roller and can be removed from the inking unit by that movement.

Abstract: A printing unit has a printing forme cylinder. A plate changer is arranged in a manner which is allocated to the printing forme cylinder. The plate changer has a bearing surface on which a printing forme, which is arranged or is to be arranged on the printing forme cylinder, can be laid. That bearing surface is arranged such that it can be moved to and fro between at least two defined positions longitudinally with respect to the rotational axis of the printing forme cylinder. The printing forme is arranged and registered on the bearing surface of the plate changer. At least two edges of a carrier for the relevant printing forme, which are arranged at a right angle with respect to each other, are brought into physical contact with register pins which are arranged on the bearing surface of the plate changer.

Abstract: An inking unit of a printing unit and a device for printing on hollow bodies each have a cylindrical lateral surface. The device comprises the inking unit. The inking unit has an anilox roller which receives a printing ink from an ink reservoir and has an inking roller placed against a printing cylinder of the printing unit. A rider roller is arranged axially parallel to the anilox roller in a region between the ink reservoir and the inking roller, that region being located subsequent to the ink reservoir in a direction of rotation of the anilox roller. The ink reservoir interacts with the anilox roller. The rider roller is placed against the anilox roller. The rider roller is rotationally driven by the anilox roller by friction. The inking roller is rotationally driven by the anilox roller by friction. The plate cylinder and the anilox roller are each independently rotationally driven by a motor.

A conveying device conveys the hollow elements to be printed into a printing zone of at least one of the printing units. At least one of the printing units includes a plate cylinder to which a plate replacing mechanism is assigned.

Abstract: A method is provided for adapting settings, which are relative to each other, of printing heads of a printing unit of a printing machine. Data regarding settings, which are relative to each other, of at least two printing heads belonging to a first subset of printing heads are detected in a first partial detection process. Data regarding settings, which are relative to each other, of at least two printing heads belonging to a second subset of printing heads and not belonging to the first subset are detected in a second partial detection process. Data regarding at least one setting of at least one first printing head of the first subset and of at least one second printing head of the second subset, which settings are relative to each other, are detected in a complete detection process. At least the first partial detection process and the second partial detection process proceed at least partially simultaneously.

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 rotary printing press has at least one printing group with at least one waterless planographic printing forme. An inking unit is assigned to the printing group as is provided with a screen roller for use in conveying printing ink to the printing group. The screen roller has line engraving or cross-hatchings, with an angle of inclination or an angle of rise of between 50° and 80° and preferably also has a raster frequency of less than 80 lines or cross hatchings per centimeter on its surface area.

Abstract: Transfer of printing ink is adjusted using a first roller in an inking unit of a printing machine, which transfers ink to a forme cylinder. A temperature control unit enables an outer surface of the first roller to reach a required temperature and/or to enable an outer surface of the forme cylinder to reach the required temperature. That temperature control unit can be either controlled or regulated by an adjusting device. Specific curves or reference points for an interrelationship between a production speed of a printing machine and the respective required temperature on the outer surface of the forme cylinder, or on the outer surface of the first roller are stored in a storage unit of the adjusting device for various printing inks or ink types.

Abstract: An adjustment of a transfer of printing ink is accomplished by arranging a first roller in an inker unit and by using that first roller to transfer ink to a forme cylinder. A temperature is adjusted on an outer surface of the first roller by the use of a first temperature control unit which includes an adjuster device. The adjuster device also adjusts a temperature to be set on an outer surface of the forme cylinder by the use of a second temperature control unit. These two temperature control units adjust parameters of the printing ink through the controls of the outer surfaces of their associated first roller and forme cylinders. The parameters of the printing ink which are adjusted are preferably the ink's tackiness and its viscosity.

Abstract: A printing blanket or dressing includes a dimensionally stable carrier plate which has ends that can be secured to a transfer cylinder. A coating is applied to the carrier plate and forms the lateral surface of the transfer cylinder. A recess is located in the printing blanket or dressing intermediate the ends of the blanket or dressing.

Abstract: The contact pressure between an adjustably mounted first cylinder and a second cylinder in a printing machine, and particularly in a web-fed printing machine can be adjusted. An actuator is usable to force the first cylinder toward the second cylinder with an adjustable force. A fixing device is usable to fix the first cylinder in a desired position relative to the second cylinder.

Abstract: A pressure force exerted by first and second cylinders upon at least a third cylinder in a printing machine is regulated by a pressure regulating device. The device can also be using for moving a first cylinder and at least one second cylinder into and out of contact with a third cylinder. Actuators, which exert a radial force on a cylinder cooperating with the actuators, are provided. An aperture angle between the radial forces exerted by two actuators on the same cylinder is the same in both cylinders. That aperture angle is independent of an aperture angle formed by the pressure force exerted by the first and second cylinders on the third cylinder.
