ABSTRACT:
In a stapling system with a power driven stapler unit for stapling sheets together by clamping the sheets together with a clamper and driving a staple into the sheets with a staple driver while the sheets are clamped, and clinching the legs of the staple with a clincher, sequentially in that order; a single flexible cable with internal bights thereof operatively connecting with the clamper, the staple driver and the clincher, and with a free portion of the cable extending from the stapler unit and pulled with increasing movement and tension to provide the sole actuating power for the stapler unit wherein sequentially coupling pulleys engaged by the internal bights of the single flexible cable, and movement stops and/or resistance springs of different resistance forces, respectively operatively associated with the clamper, the staple driver and the clincher actuate them in that order, and wherein paired pulleys are arranged to multiply the forces available for the stapling from the cable tension.
