Passive clincher and stapler incorporating same

摘要

A passive clincher and a stapler incorporating same are described. The clincher has an anvil (30) to which staples are applied during a driving operation of the stapler. The anvil (30) is formed with a depression or opening (35) between the clinching grooves (31) and is of size to include the adjacent ends of the grooves. The depression or opening (35) assists in controlling the bending of the legs of the staple during a stapling operation to prevent re-entry or re-penetration of the legs into a set of sheets being stapled.
