ABSTRACT:
Apparatus for shearing elongated products such as rods, bars and the like moving longitudinally along a path of travel. The apparatus includes a pair of constant diameter helical blades mounted for rotation about axes parallel to the path of travel. The rotational orientation of the blades and the spacing between their respective axes is such that segments of the blades coact along a cutting path parallel to the path of travel. The blades are rotated in opposite directions to thereby cause coacting segments thereof to move repetitively along the cutting path in the direction of product movement. A switch diverts the products from the path of travel across the cutting path for shearing by the coacting segments of the cutting blades.
