1. A binding machine comprising:
- a body;
an actuator coupled with the body; and
a punch mechanism housed in the body for punching a stack of sheets upon actuation of the actuator, the punch mechanism includinga plate including a plurality of punch pins, the punch pins configured to punch through the stack of sheets during a punch stroke, the punch stroke defining a force profile, a portion of the force profile defined from a first drop in force to a last peak force before a final decrease having no more than a 15 percent change in force relative to a normalized maximum force of the force profile.

Abstract
A binding machine includes a body, an actuator coupled with the body, and a punch mechanism housed in the body for punching a stack of sheets upon actuation of the actuator. The punch mechanism includes a plate including a plurality of punch pins. The punch pins are configured to punch through the stack of sheets during a punch stroke, the punch stroke defining a force profile. A portion of the force profile defined from a first drop in force to a last peak force before a final decrease has no more than a 15 percent change in force relative to a normalized maximum force of the force profile.

15. A binding machine comprising:
-
a body; an actuator coupled with the body; a punch mechanism housed in the body for punching a stack of sheets upon actuation of the actuator, the punch mechanism including a plate including a plurality of punch pins configured to punch through the stack of sheets during a punch stroke; a shaft coupled with the actuator such that movement of the actuator causes rotation of the shaft; and at least one cam mounted on the shaft for rotation therewith, the cam coupled with the plate to drive the plate in a punching direction, the cam including a cam profile that dictates displacement of the plate in the punching direction relative to rotation of the shaft. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
