ABSTRACT:
An electronic cam switching mechanism is used instead of a mechanical cam switching mechanism of a stamping machine or press. The former comprises a write/read memory which conducts track-wise characterizing signals ("0," "1," and "01," "10," "00"), address-controled by a travel distance measuring device to subsequent devices, by means of which the control signals corresponding to the binary positions of the mechanical cams are formed.
