ABSTRACT:
A perforating apparatus according to the invention has a hollow shaft having two open ends, a disc mounted on the hollow shaft and rotated together therewith, a shaft, a plurality of holding arms, a rotating mechanism for rotating each holding arm about the axis of a filter cigarette, a laser generating source, and an optical system. The holding arms are arranged on the periphery of the disc, in the circumferential direction thereof, and hold filter cigarettes such that the filters project from the holding arm. The laser generating source emits a laser beam into the hollow shaft, toward one of its open ends and at a predetermined pulse separation. The optical system has a reflecting mirror which rotates together with the hollow shaft. The reflecting mirror has reflecting surfaces which correspond to the holding arms and reflect the laser beam toward the outer periphery filter. The optical system additionally has a focusing lens for focusing the laser beam on the outer periphery of the filter.
