Abstract
A flying shear has leader and follower blades rotating in opposite directions about parallel axes located above and below a horizontal plane. The radius of rotation of the leader blade is longer than the radius of rotation of the follower blade. The blades are configured and arranged to coact in a radially overlapping relationship at a cutting zone spaced vertically from the horizontal plane. A switch directs longitudinally moving products such as bars, rods and the like from the horizontal plane across the cutting zone for separation by the rotating blades into leading and trailing segments.
