Abstract
A cutting mechanism having a movable carriage and two cutters. Each cutter has an anvil that opposes a blade, and one of these is a roller that rolls against the other for progressively biasing material against the blades, producing cuts through the material. The rollers are rotatably mounted to the carriage, which is mounted to a lead screw that controls the position of the carriage. As the carriage moves across the material, the rollers roll, and the material is cut. The space between the anvil and the blade of at least one of the cutters can be varied to disengage that cutter so that the rolling of the roller will not cut the material. The engagement and disengagement of the cutter is dependent on the position of the carriage.
