ABSTRACT:
A continuous beam from a laser is divided into two intermittent beams by a reflecting disc with peripheral holes, rotating about an axis skew to the continuous beam. At least one of the intermittent beams is transmitted to a marking head having a lens which focuses the beam onto the surface of a roll. The roll is rotated and the marking head is moved along the roll, in synchronism with the rotation of the disc, so that a regular hexagonal lattice of microcavities is cut by the focused intermittent beam. The second intermittent beam may be used to cut microcavities in the roll or in a second roll or for other purposes.
