The invention relates to a sealing element for an ink chamber of a rotary printing press, wherein the sealing element has a sealing surface that rests against a roller body during operation of the rotary printing press. In order to reduce wear on the sealing element, the sealing surface has at least one flow outlet opening, at which an overpressure of a fluid may be built up during operation of the rotary printing press, in such a way that the fluid between the sealing surface and roller body forms a sealing flow film.

Sealing element for a doctor blade chamber

The invention relates to a mixing device for mixing a fluid in a container, in particular of a fluid system, comprising a fluid supply and at least one outlet arm with an outlet opening, the fluid supply being connected to the at least one outlet arm in a fluid-communicating fashion. According to the invention, the outlet opening, for an outlet of the fluid, is oriented towards an outlet direction in order to set the fluid in the container rotating at least in sections thereof.

Mixing device comprising at least four outlet arms having diverse vertical angles

The invention relates to a drying device () for a drying between inking units of a printing machine (), with which a substrate () can be transported via rotating cylinders () and is printable with a coloring agent (), with

Drying device, system comprising a drying device and method for operating a drying device for drying between inking units of a printing machine

A device for setting at least one operating parameter of ink for a printing process of a rotary printing press having an inking system which has a doctor blade device with a doctor blade chamber containing the ink for the printing process, and an ink reservoir from which ink can be supplied to the doctor blade chamber, includes a supply system which allows ink to be supplied inside the inking system. The supply system can be switched to a setting mode (I) or to a production mode (II), the operating parameter being automatically set in the setting mode (I) and no ink being supplied to the doctor blade chamber, and the supply system supplying ink to the doctor blade chamber in the production mode (II).

Device for adjusting an operating parameter of ink for a printing process of a rotary printing press as well as method therefor

A system for measuring the viscosity of printing ink during a printing and ink correction process includes a printing press having an ink supply system, and an optical measuring device for measuring actual optical values of light that has interacted with at least parts of the printing picture. The printing press has an ink mass determination device to determine the weight of at least parts of the ink located in the ink supply system, and a control and evaluation device to receive measured values from the optical measuring device and from the ink mass determination device. The control and evaluation device determines an optical deviation, and, based on the optical deviation and the values from the weighing devices, an amount of corrective ink that is to be fed to the printing press in order to approximate the actual optical values to optical reference values.

Language and method for measuring the viscosity of printing ink during the printing and ink correction process

A method of operating a printing press includes transferring ink from an inlet point to a printing substrate, and measuring actual optical values of light, in which the actual optical values are from light of selected wavelength ranges and in which the light has interacted with at least parts of the printed image. The method includes providing a control and evaluation device with measured values from an optical measuring device and with measured values from an ink mass determination device so as to determine an optical deviation of actual optical values from optical reference values, and determining an amount of corrective ink that is to be fed to the printing press in order to approximate the actual optical values to the optical reference values.

A printing press dryer having an excimer radiant heater adapted for high energy output and compact mounting within the printing press. The heater includes a housing () within which a plurality of radiant tubes () are arranged in parallel relation to each other, and the radiant tubes () each have a respective adjacent reflector section () for directing a predetermined radiation distribution on passing printed sheet material.

Printing press dryer having an excimer radiant heater

A drying apparatus for a sheet-fed offset printing machine which dries sheets as they pass along a sheet path with forcefully directed air and/or heat. The drying apparatus of the present invention is adapted for more effective sheet drying by means of an electrode and a corresponding counter electrode, wherein the electrode is connected to a high-voltage source and a high voltage is applied to the electrode by the high-voltage source in dependence on the operation of the sheet-fed printing machine and/or the length of the sheets.
