Abstract

A wire cutter which is particularly suitable for use in a stitcher for binding sets of sheets consists of a hardened steel block 2 with a wire feed passage 4 in it opening into a slot 6. Extending perpendicularly to the passage 4 is a closely-toleranced bore having its axis intersecting that of passage 4. Seated in the bore is a rotary cutter shaft 8 able to be rotated by a gear wheel 10 (Figure 2). The shaft has a slot machined in it to form a D-sectioned part 12 aligned with passage

4.

The wire to be cut is fed into passage 4 and protrudes for a chosen length (sufficient to form a staple) from beyond face 14. At an appropriate stage, shaft 8 is rotated in the direction of arrow 16 to shear the wire between one edge of part 12 and the edge at one end of passage 4.
