The machine does not use staples as we know them in the common desktop stapler. It has a spool of wire, lengths of which it punches through the materials being bound, folds twice, and cuts. As the Stitcher model name suggests, it functions like a sewing machine for wire staples. One stomp on the foot pedal produces one staple, the length of which can be controlled by the configuration of some parts inside the head of the machine. Move the materials to be bound along and step on the pedal again.
