Abstract
A stapler having an improved anvil to which staples are applied during a driving operation by a driver member for the apparatus. The anvil includes two pivotal ears each of which is formed with a cutting edge which cooperates with a fixed cutting edge arranged to cut the excess portions of staple legs. The length of the portions being cut is in accordance with the number of sheets being stapled, the less the number of sheets, the longer length being cut.
Claims1
In a stapler apparatus having a staple dispensing means being adapted to cooperate with an anvil mechanism to permit individual ones of staples to be dispensed toward and against the anvil mechanism to perform a stapling operation;
- and wherein the anvil mechanism includes two movable clinching members for bending legs of a staple after being driven through sheets to be stapled;
- and a power device for actuating the clinching members;
- the improvement including:
- a member mounted adjacent the anvil mechanism and having a pair of cutting edges thereon,
- each of the clinching members being formed with a cutting edge cooperable with one of said cutting edges respectively, during bending of the legs, and
- a drive means connected to the clinching members for actuating the same to bend the legs of the staple thereby effecting cutting of the legs during clinching thereof.
