    摘要: A device for spotwise imaging printing surfaces includes a laser light source producing at least one laser beam movable relative to a printing surface, the laser beam defining an image spot on the printing surface, the laser beam having a laser power. A laser control varies the laser power or an exposure time as a function of a distance of the laser light source from the image spot.

    摘要: Process for producing pourable powdered rubber with filler content independent of particle size. By adjusting to a pH in the range of 3.7 to 6.5 after the mixing of rubber latices or aqueous emulsions of rubber solutions with filler suspensions containing precipitant, and by using 0.1 to 2.0 phr of a selected metal salt, powdered rubbers can be produced with filler content independent of particle size.

    摘要: A device for supplying radiant energy onto a printing substrate (14), including at least one radiant energy source (10) whose light (12) impinges on the printing substrate (14) on the path (16) of the printing substrate (14) through a printing press at a position (116) downstream of at least one printing nip (18) in a printing unit. The radiant energy source (10) emits light (12) having a peak-to-valley homogeneity of less than 15% in a direction transverse to the direction of the path (16) of the printing substrate (14).

    摘要: A sheet processing machine, in particular a sheet-fed printing press, includes a varnishing unit and at least one combination drier for applying radiation energy and heated air to a newly varnished sheet. The at least one combination drier includes a plurality of circular or polygonal air nozzles and narrow-band high-power infrared light sources disposed between the air nozzles. The infrared light sources apply radiation at a radiation density of at least 25 kW/m2 in total to the varnished sheet. The temperature of the heated air passing through the nozzles is below 100° C., preferably below 80° C. A method of drying sheets is also provided.

    摘要: Finely divided, pulverulent rubbers containing filler which contain further processing and vulcanization auxiliaries necessary for the production of vulcanizable rubber mixtures, which rubbers are pourable even after exposure to mechanical action, and to a process for the production thereof. The rubber powder is obtained within two precipitation steps. These rubber powders are used for the production of vulcanizable rubber mixtures. The fillers used, which comprise not only precipitated silicas but also carbon blacks known in the rubber industry, are optionally surface modified with organosilicon compounds.
