A stapling machine has a magazine, a guideway for sets of staples, a delivery plunger for feeding sets of staples through the guideway, and a plunger at one end of the guideway adapted to drive the frontmost staple into the desired surface. In accordance with the invention, successive driving strokes are initiated by actuation of a power supply to the plunger by means of an actuator which depends on relative movement between the stapling machine and the surface. In one embodiment, a surface engaging roller trips a micro-switch once per revolution to drive in one staple per revolution. |
