<p>A wire stitcher for binding sheets into sets in which cut lengths of wire are formed into staples about an anvil 104 by a former 105 and the formed staples are driven by a driver 106. The wire W is gripped against the anvil 104 by the driver 106 during forming and the staple is supported with the aid of the anvil 104 during driving. The driver 106 has a two-stage action in which a first stage motion operates to grip the wire W against the anvil 104 during forming, the driver motion being arrested during forming, and a second stage motion acts following forming to effect driving. The movement of driver 106 and former 105 is effected by a continuous travel of an input lever 404. (Figure 5).</p> |
