    In a machine for riveting brake linings onto brake shoes, rivets are fed consecutively to a top dolly (10), which after the introduction of a rivet into a workpiece, performs the rivet deformation conjointly with a stationary bottom dolly (11). In the bottom dolly a spring-loaded centering pin (25) for workpiece alignment projects beyond the dolly head in the initial position. The top dolly (10) projects into a bore (12) of a housing (13) forming a rivet die plate which slides relative to the top dolly (10) and contains a rivet inlet (15) open to the side and connected to a rivet slide rail (8). A slider with a bevelled end face projects into the bore for initial engagement by a rivet, the slider being pushed aside before the rivet contacts the centering pin. <IMAGE>
