A b s t r a c t The machine for the manufacture of cams from sheet metal has a press stern (10) which is surrounded by a number of ram assemblies (11) carrying dies (12) coopera- ting with punches (13) attached to bolster (14) of circular shape. A cyclindrical cam (21) cooperates with ram assem- blies (11) through follower rollers (22, 23). The cam is driven by gears (32, 33) and a crankshaft (36). The corresponding transfer mechanism comprises a- transfer ring (43) provided with three mounting pins (42), two idling arms (44) and a driving crank (41). As the shaft (40) rotates, the ring (43) gyrates about the center of the press stern (10), the two idling arms (44) always maintaining a parallel relationship to the crank (41). Six pockets (P1 to P6) are attached to the transfer ring (43) - according to Fig. 8-1 one pocket (1) collects a blank from the supply conveyor, whereas another pocket (2) makes contact with the component in the first tool (1) etc. The interaction between transfer pockets of the ring (43) and the locating rings attached to the tools (T1 to T5) ensures complete control of the components during transfer, nest means being provided at each tool including a plurality of spaced prongs cooperating with spaced fingers provided on each pocket (P1 to P6). Fingers and prongs are arranged in such a manner that the fingers of an empty pocket member pass between the prongs of the nest means and remove a component located at the tool station. The components are thus advanced from one tool station to another along a circular path, the tools being operated consecutively by said cam (21) and thereby sub- jected to a periodical reciprocating action.
