ABSTRACT:
In a binding machine wherein mechanical binding elements are first placed through a sheaf of papers and the surplus lengths of the studs of the binding element are cut off, an improved knife is provided wherein the knife is in the form of one or more U-shaped segments. In a preferred embodiment of the invention, the arms of the U which at least partially support the binding elements also serve to move locking blocks into place. The blade element is at the bight of the U and the blade is slid along the back of the female binding element to cut off excess stud lengths flush with the binding element.
