<p>A laminar staple comprising two walls (2, 3) arranged at an angle and two ribs (5, 6) which protrude laterally from the walls (2, 3); the walls (2, 3) and the ribs (5, 6) form a substantially W-shaped profile which has a cutting edge (7) at one end and a striking edge (10) at the opposite end; the staple is peculiar in that the ribs (5, 6) enclose, by means of their respective walls (2, 3), an angle whose value decreases from the cutting edge (7) to the striking edge (10).</p> |
