ABSTRACT:
A stapling apparatus is disclosed having an arrangement to prevent the repenetration of one or more legs of a staple during stapling of a low number of sheets, say on the order of 2, 3, 4, or 5 sheets while utilizing a staple of a size for 20 sheets or more. The invention is an improvement of a commercial machine which it modifies by adding a back up member to the staple deforming mechanism during penetration of the legs of the staple through sheets of paper and final bending of the legs in a stapling operation.
