Abstract: A discharge device for discharging electrostatic charges from a shaft, in which the discharge device comprises a holder, a spring element disposed on the holder, and at least one conductor disposed on the spring element and running perpendicular to a longitudinal shaft axis. The conductor has a shaft contact portion for making contact with a circumferential contact area of a shaft circumference in such a manner that the shaft contact portion is tangential to the shaft circumference when in contact with the shaft circumference.

Abstract: An apparatus for metering printing ink includes an ink fountain roller, an ink fountain and a mounting for the ink fountain. The mounting permits an adjustment of the ink fountain relative to the ink fountain roller. The mounting has at least one elastic element for generating a holding force. The mounting is configured in such a way that a force flux which results from the holding force deflects the ink fountain roller in such a way that its longitudinal outer contour is adapted to the longitudinal outer contour of the ink fountain. A printing press having the apparatus is also provided.

Abstract: The invention relates to polyolefin materials, in particular fibers, and/or filaments, and/or nonwovens, and/or nonwoven products made from at least one polyolefin and a melt additive containing a fatty acid ester, wherein a subsequent activation of the fatty acid ester contained in the melt additive occurs on the surface of the polyolefin materials by applying a formulation, which contains a silicone compound and a quaternary ammonium compound.

Abstract: The invention relates to a process for the production of a collagen implant for wound covering, in which a suspension comprising a telopeptide-containing collagen is produced and a phosphate buffer is added. An areal structure is produced by drying the collagen-containing mixture produced.

Abstract: An inking unit includes a first smoothing roller, an ink feed unit constructed as an ink droplet generator for applying a metered quantity of ink to the first smoothing roller, by one of an indirect and a direct path, respectively, the indirect path being via at least one additional roller interposing the ink feed unit and the first smoothing roller, and the direct path being directly to the first smoothing roller, and further including a second smoothing roller operatively connected to the first smoothing roller for distributing the application of ink, each of the first and the second smoothing rollers having a hard smoothing surface with a hardness of one of at least 80 Shore A and at least 30 Shore D, respectively, for forming a uniform film of ink; and an offset printing machine including the inking unit.

Abstract: An inking unit in a printing machine, formed as a film inking unit, includes an ink duct with an ink duct film inserted between an ink metering system, which is subdivided into ink zones, and an ink duct roller. The ink duct film within each of the ink zones in a region of a settable metering gap is held out of contact with the ink duct roller during printing. The invention also includes a printing machine, such as a sheet-fed printing machine, particularly, provided with the inking unit.

Abstract: An inking unit for a printing machine includes one or more distributor drums, ink transfer rollers, ink application rollers, an ink reservoir for printing ink and an ink metering device having at least one electrically controllable valve for metering the printing ink. In accordance with the invention, there are provided a high-pressure pumping device for supplying the ink metering device with printing ink at a predetermined high pressure from the ink reservoir, and a heating device for heating the printing ink to a predetermined temperature above room temperature. Moreover, the at least one valve of the ink metering device has a short reaction time and a flow rate with a low dependence upon viscosity. The invention also relates to a method for supplying printing ink to a printing machine.

Abstract: A method and devices for cleaning an inking system of a printing machine in which a further drive of the inking system (1) is used for the reverse transport of the ink into the ink fountain (4), while the clock-pulse movement of vibrator roller (5) between ductor roller (6) and distributor roller (7) continues to take place, and that only after this reverse transport of the ink is the customary cleaning of the inking system (1) carried out.
