Abstract
A stapling device has a holddown element, a staple forming member, and a staple driving means, which are guided linearly and are movable perpendicular to the upper side of a sheet stack to be stapled. A first pressure spring with a lower spring force is associated with the holddown element. A second pressure spring whose spring force is greater than that of the first pressure spring, is associated with the staple forming member. A third pressure spring is associated with the staple driving means, its spring force being greater than that of the second pressure spring. The pressure springs are arranged with identical working directions perpendicular to the upper side of the sheet stack. The first pressure spring is arranged in preloaded fashion between the holddown element and the staple forming member. The second pressure spring is arranged in preloaded fashion between the staple forming member and the staple driving means. The third pressure spring is arranged in preloaded fashion between the staple driving means and a drive head on which engages an eccentric drive which moves the stapling device in the direction of the arrow onto sheet stack, and thereby controls a force-controlled drive mechanism of the stapling device in an operationally correct sequence.
