A staple driver (9) is provided, which is adapted to be mounted in a stapler for driving staples into a sheaf of papers (11) in order to drive, in a striking motion, the legs of a U-shaped staple (10) through the sheaf of papers (11). The driver (9) has a plate-shaped portion (13) with an edge surface (14) which is arranged, in the striking motion, to be applied and pressed against the web portion of the staple (10). The staple driver (9) has pointed projections (12) which are arranged to engage, in the striking motion, with the web portion of the staple (10) in front of the legs of the staple. The edge surface (14) of the driver (9) extends in its longitudinal direction along an outwardly curved arc. |
