Abstract:
A shear for subdividing an elongated product moving longitudinally in a plane, said shear comprising:leader and follower blades mounted on rotors for rotation about parallel axes located on opposite sides of said plane, said blades being arranged to coact in a radially overlapping relationship at a cutting zone located between said axes and spaced vertically from said plane, the radius of rotation of said leader blade being longer than the radius of rotation of said follower blade; means for continuously rotating said blades at equal angular velocities, with said leader blade preceding said follower blade in said cutting zone; and switch means located upstream of said cutting zone, said switch means being operable in a first mode to direct said product along a path in said plane bypassing said cutting zone, and being operable in a second mode in concert with one of said rotors to deflect said product from said path and said plane into said cutting zone for cutting by said blades into leading and trailing segments, said blades being constructed and arranged to further deflect a tail end of said leading segment away from said plane while directing a front end of said trailing segment back to said plane.
