Abstract: The invention relates to an assembly of members for programming and controlling the process of a blanking or die cutting machine, which process, because of simply comprising shearing machine blows, is programmed and controlled by merely fixing before hand the amount of blows that the machine should give, and then controlling the given blows. The invention is characterized in that the assembly or unit comprises a filing cabinet intended to accomodate the blanks or die cuts to be used for the process, each file being provided with members responsive to the presence of said blanks or die cuts, so that as a blank or die cut is withdrawn or picked up, the relative programming members are activated as set on the control board.
