Abstract

An automatic numerically controlled slotting or notching press arrangement which includes a multi-armed feed and removing device having a turnstile or turntable which is selectively indexed or rotated so as to convey blanks to various processing stations. The feeding and removing device is adapted to transfer the blanks from at least one stack unloading station to a centering or aligning station, a locating or turning station, a processing station, a stator stacking station, and a rotor stacking station. A numerically controlled indexing unit (a clamping table for blanks to be processed) and a numerically controlled tool changing is provided. The stack unloading station and the rotor stacking station form the first and last processing stations and are linked by a conveying device which operates independently of the turnstile or turntable of the feeding and removing device.
