The invention relates to a loading method for a machine tool (12), especially for a bending machine, having a tool-transfer device (1), a tool holder (17) of the machine tool (12), and a tool rack (13), wherein the tool holder (17) and the tool rack (13) are connected via a guide rail (4), and the tool-transfer device (1) has a magnetic retaining device (5). The tool-transfer device (1) is moved to a machining tool (18), which is arranged in a pick-up position (20) in a tool holder (17) or in a tool rack (13). The machining tool (18) is picked up and retained by means of a magnetic retaining device (5) of the tool-transfer device (1) and moved along the guide track (4) to a deposition position (21). There the machining tool (18) is deposited by deactivation of the magnetic retaining force (22). The magnetic retaining device (5) has an electromagnet (6) having an electronic activating device (7) wherein, upon deactivation of the magnetic retaining force (22), a demagnetization is performed by the activating device (7).
