A staple wire supply roll is positioned on a threading-in device that can be moved out of a stapling apparatus, and the leading end of the wire is transported by means of a thread-in transport device, through a flexible guide tube, to a stapling device. A sensor positioned on the stapling device signals the end of the threading-in operation when the leading end of the staple wire passes by. By pushing the threading-in device into the apparatus, the staple wire transport device of the stapling device is set in motion, as a result of which the leading end of the staple wire is transported to a location which positions the leading end of the wire in device. The staple wire is transported, in accordance with the thickness of the sheet stack measured by a sensor, by a stepping motor, which at the same time drives a radial cam unit. The radial cam unit moves a cutting device into a position in which the transported staple wire segment is positioned symmetrically with respect to a shaper and driver of the stapling device and cut, and then shaped into a staple and driven into the sheet stack.
