ABSTRACT:
An apparatus in which a set of sheets is stapled together. A predetermined length of wire is fed to the stapler. A wire cutter is positioned along the wire as a function of the movement of the clamper clamping the sheets of the set. The wire cutter cuts the wire at the cutting position and a forming bar forms the cut wire into a staple. A driving bar then drives the staple through the set of sheets to staple the sheets together.
