ABSTRACT:
An apparatus in which articles are stapled to one another. A staple is driven through the article so that a portion thereof protrudes therefrom. The staple legs protruding through the articles are bent into substantial contact therewith so as to clinch the staples. In the clinched position, the staple legs are closely adjacent to one another and may be overlapping. During the clinching operation, the staple legs are guided by a groove in the surface affecting bending. Initially, the stapled leg is received in the central region of the groove. The central region of the groove has a greater cross-sectional area than the end region thereof.
