In a device for edging and folding metal sheets, a press roller (9) secured to operating levers (6) can be brought into at least one additional position. The metal sheet (11), together with a cylindrical shell (10) is fixed between the flanges (1, 2) or on the outer surface of a curved flange (1, 2), so that when the operating lever (6) is actuated, the metal sheet (11) comes to bear against the shell (10) or the curved flange (1, 2). |
