Abstract: An electromechanical device associated with table staplers for automating the operation of such staplers. A box-like body houses and restrains a conventional table stapler. The body is provided with a camming member for controllably pressing on the movable arm of the stapler, to cause a metal staple to be ejected and its ends to be bent against the die arranged on the fixed arm of the stapler. A timer device releases the arm of the stapler and resets the camming member after a preset period of time.
