Abstract:
A shear for subdividing an elongated product moving longitudinally in a horizontal plane, said shear comprising:a) first and second sets of upper and lower continuously rotating blades respectively coacting in a radially overlapping relationship at first and second cutting zones located above said plane, said first cutting zone being located between first and second paths, and said second cutting zone being located between said second path and a third path, the radii of rotation of said lower blades being longer than the radii of rotation of said upper blades, and b) switch means located upstream of said cutting zones, said switch means being operable sequentially: (i) to direct said product along said first path bypassing said cutting zones; (ii) to divert said product in one direction from said first path across said first cutting zone to said second path, said product being cut by the blades of said first set into a leading segment continuing along said first path and an intermediate segment continuing along said second path; and (iii) to divert said product in the same direction from said second path across said second cutting zone to said third path, said product being cut by the blades of said second set to separate said intermediate segment continuing along said second path from a trailing segment continuing along said third path.
