Abstract

The laser is used to perforate cigarette paper on a continuous basis by focusing the beam inside the paper when formed into a tube (1). This beam (2) is projected along the longitudinal axis of the tube until it reaches a flat plane mirror (3). The beam is then reflected (2') at 90 deg. to form the radius of a circle of rotation having an axis co-axial with the tube. A focusing lens (4) concentrates the beam (22) onto the sides of the paper tube. The perforations are pitched in accordance with the holes (6) spaced around the circumference of a plastic mask (5) fitting inside the tube.
