[origin: EP1389498A1] Two thin metal plates (5,6) such as might be used for a car door are placed on a die (7) and a robot (1) with arm (2) and head (3) joins them at the edges. The head consists of an arm (9), roller (8) and means to pull or push the roller evenly which use an electric motor with a mechanical or hydraulic transmission. The edge of the lower plate is bent over the edge of the second plate and the two are then crimped by the same roller and robot : An independent claim is also included for : Equipment able to assemble thin metal plates which uses a robot head and roller able to bend one peripheral plate edge over the other and then crimp the two together in consecutive uninterrupted operations.
