Title: Edging device

Abstract: An edging device or hemming device is disclosed with a machine frame (1), an edging bed (2) which is positioned inside said frame where it is raised and lowered with an edging lift and/or a displacement lift. A plurality of edging jaws are provided, which can be moved into the working area of the edging bed (2). Drive mechanisms are provided for the edging bed (2) and the edging jaws (3). The drive mechanisms for the edging lift and the displacement lift are configured as electromechanical drive mechanisms (7) which move the edging bed (2) using driven eccentric cams (12) or cranks. This simplifies the control of the drive mechanisms and reduces the masses of the structural parts being moved.
