<p>A machine (1) for flanging metallic containers (2) comprises at least a pair of flanging plugs (7a, 7b) mutually opposite and coaxial, located downstream of a station (4) for feeding the containers (2) and upstream of a station (5) for offloading the containers (2). The plugs (7a, 7b) are movable relatively and alternatively along their own common axis (70) from a distance at least corresponding to the height of a container (2) to a distance whereat the plugs (7a, 7b) are forcibly inserted into openings (20a, 20b) of the container (2) holding it firmly and causing its flanging. In this phase, a punching die (8), integral with an outer lateral surface (71) of at least one of the plugs (7a or 7b) of the pair, cooperates with a punch (9) to produce tactile warnings on the lateral walls (20) of the container (2). The plugs (7a, 7b) are also movable according to a second common motion component along a trajectory lying in a plane perpendicular to the common axis (70) of the plugs (7a, 7b). The punch (9) participates in the motion of the pair of plugs (7a, 7b), thrust on the punching die (8) by the interaction with at least an element fixed to the support structure 3, comprised in actuator means (10) for actuating the punch (9) and located in a predetermined point of the trajectory of the second motion component of the plugs 7a, 7b). <IMAGE></p> |
