ABSTRACT:
A laser-cutting machine produces slots of computer-controlled size and pattern in workpieces of cylindrical-shell configuration, the workpieces being mounted for incrementally controlled rotation about the axis of each workpiece, in coordination with incrementally controlled longitudinally guided displacement of the laser along a path parallel to the workpiece-rotation axis. The thus-slotted workpieces become locators for knife elements and indentation-tool elements, so that when secured to the cylindrical body of a cutting roll, the resulting tool will find use in a rotary printing process for continuously printing, cutting and creasing cardboard or other box material. The computer-control of slot pattern enables a user shop to quickly adapt its cutting and creasing operation to the custom size and configuration requirements of different customers.
