    摘要: A dampening system for a printing apparatus includes a print plate, a printing cylinder contacting the print plate and adapted to supply water to the print plate, a feed device for feeding water to the printing cylinder, and a dampening roller adapted to transfer water from the feed means to the printing cylinder. The dampening roller comprises a roller having a dampening layer composed of a substrate through which is dispersed a plurality of minute hollow bodies. A plurality of the hollow bodies open towards the circumferential surface to form cells for transferring the water from the feed means to the printing cylinder. At least one of the size and the concentration of the hollow bodies dispersed within the substrate is selected depending on the amount of dampening water to be fed to the print plate.

    摘要: A dampener roller cartridge for mounting on a cylindrical support comprising a core tube having a central bore to receive the cylindrical support, the core tube being characterized by having an annular wall thickness of at least one-third the radius of the tube, and a coherent network structure providing a density of less than 0.5, the plastic substance and the network structure providing the tube with sufficient resilience to be resiliently deformed by a radially applied force by a mating roller and to recover its original shape after the cessation of the radially applied force, and further providing the core tube with sufficient rigidity to permit tight slidable mounting of the core tube on the cylindrical support, and a moisture-absorbent, outer sleeve secured about the circumference of the core tube. Also disclosed are securing a fabric sleeve to a core tube by heat-shrinking and double-sided adhesive tape near the ends of the core tube to prevent axial and circumferential slippage of the sleeve; and an assembly for supporting a dampener roller cartridge on a support cylinder between two end caps, one of which is held against the support cylinder via threaded axial connectors.
