An apparatus (10) has a punching station for automatic fixation of self-piercing fasteners (2) each having a stud (3), a flange-shaped head (4) and a cylindrical lug (5) at one end of the stud. With the fastener being struck to a metallic panel (1), the lug (5) pierces it and an open rim (6) of the lug is deformed by a caulking die (11) to firmly attach the fastener to the panel. The apparatus has a feeding section (28,29) for arranging the fasteners in a continuous horizontal row perpendicular to a pressing punch (12), with the lug (5) preceding the stud. A transportation mechanism (35) receiving the fasteners from the feeding section can grip, tilt and transport the fasteners successively to the punching station where each fastener (2) is precisely aligned with the pressing punch (12), so that those fasteners which have been lying on their one sides in the feeding section do reduce overall height of the apparatus, can nevertheless be surely transported to the punching station and precisely aligned with the punch. <IMAGE> |
