ABSTRACT:
A cutoff system for exterior siding which includes a flying punch and shear. The system includes a main carriage which is adapted to reciprocate and, in one direction of travel, move at the same speed as the siding to be cut. A pair of punches are then actuated to form the hanger and butt notches at the lateral edges of the siding. Upon withdrawal of the punches, the travel of the main cylinder is slowed such that the siding travels away from the punching area. Upon sensing the notched areas, the main carriage is again moved to travel at the same speed as the siding. The speed is timed such that the center of the notches is located below a shear. This shear is then actuated to form a single parting line across the siding. The carriage is then retracted to await the next cycle of the system. As such, with each cycle of the system, the notches are formed in the trailing and leading edges of adjacent panel segments, and the leading panel segment cut from the continuous siding.
