A method for determining the optimum procedure for a job change on a printing-material processing machine () with at least one control computer. The data of a first machine job is compared to the data of a subsequent machine job using a control computer, and the comparison is used to establish an order of the operations to be carried out during the job change. Also provided is a device for determining the optimum procedure for a job change on a printing-material processing machine () with at least one control computer. The control computer is intended to compare the data of a first machine job to the data of a subsequent machine job, and to use the comparison to establish an order of the operations to be carried out during the job change.

Method and device for optimizing a job change

A printing unit configuration includes an accessory and a connection mechanism moveably fastening the accessory thereto, throwing the accessory thereon into a working position, and removing it therefrom into maintenance positions. A linear guide can be connected to the accessory and disposed perpendicular to a pivot axis, with the mechanism pivoting the accessory away from the unit about the axis and displacing it along the guide. The mechanism can have two pivot axes disposed parallel to the unit rotation axis and can pivot the accessory away from the unit first about the first axis then about the second. The mechanism can pivot the accessory about an axis perpendicular to the unit rotation axis and/or about a single pivot axis disposed below the accessory. The mechanism can connect the accessory to the unit to project into a recess of a side wall of the printing machine at a side opposite an operator side in a maintenance position.

Accessory for a printing unit

An apparatus for producing a printing form which, with little expenditure, permits exact beam alignment and positioning. The apparatus for producing the printing form contains a holder for at least one printing form blank, and at least one imaging module, which can be moved relative to the printing form blank and which contains at least one radiation source which, in order to produce image elements that accept printing ink, is aimed at the surface of the printing form blank and whose beam direction can be adjusted. The imaging module being accommodated in a six-point mounting in three bearing locations, each bearing location containing a spherical element and an associated bearing element and in each case the spherical element rests on it and, in order to adjust the beam direction, at least one element of one bearing location being disposed adjustably.

Apparatus for producing a printing form

A rotary printing machine includes at least one form cylinder, at least one further cylinder, and a gear transmission via which the form cylinder and the further cylinder are drivable together during a printing operation. A device is provided for setting an image on a printing form located on the form cylinder. A switchable speed-change gear mechanism is disposed between the form cylinder and the gear transmission for driving the form cylinder during the printing operation.

A method for driving a printing press includes driving, in a printing operation, via a gear train by at least a first motor, at least one drum for advancing printing material and a printing-form cylinder, processing angle-of-rotation signals of the drum in a control device for controlling the driving of the drum and the form cylinder, and driving, in a printing-form production operation in the printing press, a printing-form cylinder by a separate motor. The method further includes, in an operation for producing the printing form, synchronously actuating the first motor and the separate motor by providing a gear allocated to the driving of the printing-form cylinder, and an adjacent gear allocated to the driving of the drum of the gear train, the gears being disposed relative to one another at the most out of contact with one another, and at the least barely in engagement with one another so as to exert a slight pressure on one another, and a device for performing the method.

A method of driving a machine related to printing technology, wherein movable elements forming a kinematic chain are coupled with one another via at least one gear mechanism, includes infeeding torque components by a respective motor of at least one group of two motors, respectively located at least at two elements associated with one another. The torque components are of equal amplitude but have opposite directions of rotation, for suppressing disruptive oscillations at least at the one group of two motors. The amplitude of the torque components is proportional to relative rotation of the two elements associated with one another. Rotary encoders are provided to obtain signals for reproducing rotational positions of the elements.

An apparatus is provided for guiding a print carrier upon feeding the print carrier to and guiding the print carrier away from a form cylinder of a rotary printing machine. Guide elements for the print carrier are disposed axially parallel to the form cylinder. The guide elements are disposed in two groups. One group serves to pull the print carrier into the printing unit, while the other group assists in the removal of the print carrier from the printing unit of the rotary printing machine. The guide elements assisting the feeding-in and exchanging of the print carrier are protected against contact with the print carrier by throw-on elements during exchange of a print carrier. A printing unit in a rotary printing machine having the apparatus is also provided.
