Abstract
Abstract A stamping machine includes a tool carrier having a receiving part, or tool carrier for a punch and for a bottom die. A cassette is provided for orienting the tool elements therein so that they may be moved into engagement with the tool carrier automatically. An automatically operable casette loading and loading device is located adjacent the tool carrier which and includes a rotatable support having a plurality of longitudinally extending distance members along which is movable a clamp or holder for a cassette carrying the tool elements. The distance members are shiftable for example, by rotation of disc plates which carry the members, so that they may be oriented downwardly in a position for receiving a cassette which has been selected from a magazine storage disc for the casetts by a selector transfer member and then shifted upwardly to a position in alignment with the tool carrier. The cassette receiver may be then shifted along the distance members to move the cassette with the tools into a position so that the tools may be easily deposited into the carrier after another one is first removed.
