Abstract: An apparatus and method for producing motor laminations from blanks uses a servo-controlled linear transport mechanism for transporting blanks a fixed stroke distance to a notching station wherein the notching station includes a stationary index spindle and movable punch head which adjusts for accommodating blanks of varying diameters. A lamination removal mechanism removes and transfers a notched lamination from the notching station to a lamination carrier by traveling a fixed stroke distance. Different diameter blanks are facilitated by adjusting grippers and the punch head while the stroke distances remain unchanged. The linear transport mechanism and the lamination removal mechanism move independently to transfer blanks and laminations at different times to improve blank throughput.

After a notch is cut, the ejector button (501) is pressed, capturing the paper cuttings and raising the cutting member to the ready position.

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.
