A stapler device is disclosed for a finishing station in a copying or duplicating machine which is arranged to produce automatically a predetermined number of copy sheet sets in accordance with a collated document stack. The copy sheets are compiled into individual sets and stapled in the upper left-hand corner of each set as viewed in a reading orientation. The staple has its bridge (crown) portion angularly related to the edges of a set corner, and for optimum strength for which the staple is capable, the angle is such as to be perpendicular to the diagonal of the set.
