Abstract
In the apparatus, a fastening element is driven into a support under the action of the gases from an explosive charge via a piston () that can move in a gun between a firing position and a fastening position, and a plug guide () in which a piston-braking ball () mechanism is mounted, which comprises arms () mounted to pivot on the plug-guide () arranged to modulate the radial force of the balls (), depending on the relative displacement of the gun () and of the piston (), between a maximum force when the piston () moves forward in the gun, and a non-zero minimum force, when the piston () moves back.
