ABSTRACT:
Elongated thin strip stock is blanked to form interlocking laminas for electric motor or generator rotors or stators at successive blanking stations. The laminas are blanked at one station and pushed back into the strip stock to be carried to a final station where the laminas are stacked and pressed into interlocking relationship. The laminas are rotated relative to one another to compensate for thickness variations.
