    摘要: Described herein are an apparatus and a method for direct engraving an elastomeric printing plate by multiple laser beams simultaneously. In one embodiment, an elastomeric printing plate or sleeve is positioned on an imaging drum for direct engraving. The imaging drum is rotatable around its longitudinal axis. Such rotation defines a circumferential direction, also called the transverse direction. The axis of rotation defines an axial direction, also called the longitudinal direction. The printing plate has an body and a surface made of an elastomer (made of polymer or rubber). A drive mechanism provides relative motion between a plurality of laser beams and the plate in both the transverse and longitudinal directions.

    摘要: This invention pertains to a method for making a cylindrically-shaped element, and particularly a cylindrically-shaped element for use as a base sleeve for printing or as a support for a print form. The method includes wrapping a sheet of a material having a first end and a second end to bring the second end adjacent the first end to form a base sleeve having an axial seam of the first and second ends. The first end has a non-linear edge having an amplitude. Portions between the first end and the second end overlap and form the axial seam. The method can include applying an imageable material adjacent an exterior surface of the base sleeve that covers at least a portion of the axial seam.

    摘要: The invention relates to a method for structuring endless belts (1), particularly steel belts, for presses, e.g. double belt presses. According to the invention, a coating is applied to an outer surface of the belt after which metal is removed from and/or applied to the belt. The coating is formed by individual drops, which are projected against the outer surface of the belt and remain thereupon and/or, as done in the prior art, a surface-covering coating is applied, which is degraded and/or removed, e.g. oxidized, in a preferably point-by-point manner by the action of thermally active beams, particularly laser beams, whereupon metal is removed from and/or applied to the uncoated area.

    摘要: A press roller exhibits an external interchangeable sleeve and an internal sleeve, which holds the external sleeve and which is provided with boreholes, which can be loaded with pressurized air, in order to facilitate the pulling on and off of the external sleeve. To feed the compressed air directly to the boreholes while avoiding buffer spaces that impede the pressure buildup, the boreholes are connected to compressed air lines, which are led through the interior of the internal sleeve.

    摘要: A sleeve-shaped printing sleeve for a form cylinder of a printing machine is fabricated from a blank of metallic material by cutting the blank to a width corresponding to the form cylinder and to an intermediate length which exceeds the circumference of the intended printing form cylinder. Additionally, the blank is provided with aligning indicia in the regions between each edge of the intermediate-length blank and the corresponding edge to be defined by cutting. Thus, these regions lie outside of the printing area. The blank is bent circularly, held in exact register in a bending/welding device, and cut to the length required for the intended form cylinder by laser beam cutters. As a result of this cutting operation, two waste pieces are produced. The waste pieces are removed and the now defined plate edges forming the beginning and end of the printing form are positioned opposite one another without overlap and welded together, preferably by a laser.

    摘要: For fitting a printing sleeve in a printing roll the outer surface of the roll core and preferably the inner surface of the sleeve are made with one end of a lesser diameter than the other; the sleeve is slightly undersize diametrically. Remote from the ends of the core are orifices whereby gas under pressure may be blown radially outwardly from the core. The difference in diameter allows the sleeve to be passed freely along the core until it jams up against an increased diameter portion of the outer surface of the roll, at which time it covers the orifices. Gas is then blown from the orifices to expand the sleeve which can then be moved into its working position on the core. A sleeve specially suitable for this treatment is made by laying-up a seamless GRP layer on a former which is undersize for the designed core and either curing a rubber layer in situ onto the layer, or adhesively securing a flexible plate to a true cylindrical outer surface of the GRP layer. A transition between the regions of different diameter of the outer surface of the roll core may be made by a frusto-conical taper (preferably of the order of 5 parts in 10,000 to 20,000) or by at least one step (preferably slightly greater than the designed undersize of the sleeve, say 0.008 and 0.006 inches respectively).
