Abstract
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.
