Abstract
A staple apparatus is installed in a stapler so the stapler can staple stacks of paper with different thicknesses without having to change staples or components in the stapler. The apparatus cuts legs of a staple to a proper length after the staple has been driven completely into a stack of paper and bends the protruding ends to bind the stack of paper together. The apparatus performs these operations with a cutter, a bending template, and a cutting anvil in conjunction with a sliding bracket and a cutter actuator. Operation of the cutter is delayed by a staple driver actuator until the staple has completely penetrated the stack of paper.
