ABSTRACT:
A method and apparatus for cutting a predetermined pattern in a moving web of material, such as paper, cardboard or the like is disclosed wherein a laser beam is deflected by a series of pivotable mirrors. The pivoting of the mirrors is controlled so as to cause the laser beam to trace and cut a predetermined pattern. The laser beam moves only in rectilinear motion, as does the web of material to be cut. Since the directions of motions are not parallel, any pattern may be cut by controlling the relative speeds of the laser beam and the moving web of material.
