  • Wire stitchers
    Patent number: 4358042
    Abstract: A wire stitcher for binding sets of sheets has a driver for driving a staple through a set and an active clincher. In one form the clincher has a drive for the clincher ears which is actuated by the driver. The drive is by a spring which is loaded during a return motion of the clincher housing at the completion of a stitching operation. In another form the clincher ear drive is effected by a cam. Both forms are capable of accommodating variations in set thickness essentially without affecting the timing of the operation of the clincher ears.

  • Stitchers

The clincher includes an ear having a first groove in a side edge for catching the end of a driven staple leg and initiating bending of the leg and a second, narrower groove in an end edge, which is contiguous with the groove and aligns the leg and completes the bending thereof. A transition groove portion connects the grooves at the junction of the edges.
