A method of producing printed products uses at least one computer and at least one input device for controlling at least one machine for processing printing substrates. The input device receives technical and economic data of at least one print shop and the computer receives customer preferences relating to print jobs by using the input device. Based on the technical and economic data of the print shop, the computer calculates a simulation of possible print jobs producible in the print shop. The computer takes into account the results of the simulation and the customer preference inputs and generates matching offers for print jobs. The computer compares the generated offers with customer print jobs and, if a match is found between an offer and a customer's print job, the print job is processed by the machine for processing printing substrates.

A printing material processing machine has an oscillating roll with a roll shaft, a roll barrel rotatably and translatorily mounted on the roll shaft, and an oscillating mechanism for moving the roll barrel to and fro along the roll shaft. The oscillating roll is mountable on a roll lock. A fixing device is provided and constructed in such a way that, in a dismantled state of the oscillating roll, in which the latter is released from the roll lock, the fixing device secures the roll barrel against displacement along the roll shaft and, in an installed state of the oscillating roll, in which the latter is mounted in the roll lock, permits the axial to and fro movement of the roll barrel.

A method of aligning a rubber blanket formed with register cut-outs, relative to a clamping device having register pins, for clamping the rubber blanket onto a cylinder, includes bringing the register cut-outs formed in the rubber cylinder into contact with the register pins of the clamping device when the clamping device has been applied to the cylinder.

A device for positioning and tensioning a cylinder dressing on a printing-machine cylinder, wherein both a leading dressing end and a trailing dressing end of the cylinder dressing are tensioned, includes, in a first step, tensioning both dressing ends, and in a second step, relieving the tension in a first of the two dressing ends, while retensioning a second of the dressing ends; and a printing machine provided with the device.

A device for ensuring correct tooth engagement during coupling of an adjustable, first gearwheel to a second gearwheel of a printing-material processing machine, includes a first adjustment device for adjusting the first gearwheel in a direction towards the second gearwheel during coupling, and further includes a protrusion and a guide for guiding the protrusion during the coupling, the protrusion being disposed eccentrically to one of the two gearwheels and being connected to the one gearwheel, so that, during rotation of the one gearwheel about a central axis thereof, the protrusion is rotatable together with the one gearwheel.

A clamping device for firmly clamping a cylinder packing or covering on a printing machine cylinder, the clamping device having a clamping seat, a clamping jaw cooperating therewith, and an eccentric shaft, includes a support wherein the eccentric shaft and the clamping jaw are jointly mounted, the support being adjustable alternatively into a first support position and into a second support position relative to the clamping seat; and a printing machine having at least one clamping device with the foregoing construction.

A method for applying an anti-corrosion protective layer to the surface of a cylinder for the printing unit of a printing press, the surface having been cleaned and microroughened, includes uniformly applying to the cylinder surface a thermally cross-linkable plastic material dissolved in a solvent, drying and, respectively curing and cross-linking the plastic material layer at an elevated temperature, and then mounting the cylinder in the printing unit without further processing the surface form; and a printing unit cylinder having a surface to which the anti-corrosion layer has been applied.

A cleaning device for cleaning an outer cylindrical surface of an impression cylinder of a rotary printing machine includes a cleaning cloth pressed against the outer cylindrical surface by a beam. The beam is pivotally mounted to engage the cleaning cloth with the outer cylindrical surface upon pressurization of a pneumatic cylinder. A spring pivotally returns the beam to disengage the cleaning cloth with the outer cylindrical surface upon depressurization of the pneumatic cylinder. To assure radial clearance between the cleaning device and the gripper fingers of the impression cylinder, the pneumatic cylinder is depressurized at a first angular position of the impression cylinder and the pneumatic cylinder is subsequently pressurized at a second angular position of the impression cylinder. The first and second angular positions of the impression cylinder correspond respectively to the cleaning device nearing the vicinity of the gripper fingers and the cleaning device leaving the vicinity of the gripper fingers. The cleaning device includes a cam roller that engages a cam plate attached to the impression cylinder to control the engagement of the cleaning device with the outer cylindrical surface upon the pressurization of the pneumatic cylinder.

Cleaning device provided on a rotary printing machine

A cleaning device provided on a rotary printing machine for cleaning the outer cylindrical surfaces of cylinders includes a pressing-on bar for pressing a cleaning cloth on a respective outer cylindrical surface, adjusting elements for engaging the pressing-on bar, and an elastic profile rail to guide and press a cleaning cloth onto an outer cylindrical surface over the entire cylinder width. The elastic profile rail receives a plurality of forces from spring elements. The elastic profile rail and the spring elements allow a uniform cleaning of the outer cylindrical surface despite the presence of uneven or rough portions of the outer cylindrical surface that might be encountered by the cleaning device during cleaning.
