Abstract (en)

On a rotatable table (14) there is mounted a pattern (15) on which a workpiece (20) to be flanged is fixed in such a way that a sheet metal edge (21) of this projects laterally from a peripheral edge (19) of the pattern (15). A flangeing head (23) is thrust by an hydraulic cylinder (24) to press a roller (27) laterally against the edge (21) to be flanged and towards a vertical surface (17) which co-operates to form the edge (19). The roller (27) is thrust between an initial raised position from which a tapered portion (33b) of the roller (27) contacts the edge (21) when it is not deformed, and a lowered position in which the edge is folded (21') beyond the edge (19) and pressed between a widened portion (33a) of the roller and the vertical surface of (17). <IMAGE>
