There is disclosed an overedge width regulating device capable of adjusting overedge width by rotating a knob which causes both a overedge-width latch and a lower knife to move simultaneously. The device permits adjustment of the overedge-width latch independently from the lower knife and the release of the overedge-width latch during the roll hemming process. Thus, without regard to material being sewn, knitted or woven, a tight and well-balanced overedge finish is obtained while, at the same time, the overedging process is greatly improved from the viewpoint of both quality and time.
