<p>An apparatus for spiral binding a stack of papers together as a unit. The apparatus includes a spiral binding unit (10) for feeding a spiral coil (28) into the holes (17) in the stack of papers, a pin extension and retraction mechanism (46), a coil cutter mechanism (34), and a paper thickness measuring and sizing mechanism (44). The spiral binding unit includes an aperture through which a spiral coil is inserted between a feed shaft (32) and a rotatably mounted roller (54). As the coil is inserted, the roller pushes the spiral coil into contact with the feed shaft. As the roller rotates, the coil is guided around a plurality of spiral guides that cause the coil to spiral into the holes in the stack of paper. The pin extension and retraction mechanism includes a plurality of locator pins that are movable between an extended and a retracted position.</p> |
