Abstract
The present invention relates to a tooth plate for an inverted tooth chain with two hinge openings spaced apart in the longitudinal direction and a tooth plate contour with two teeth arranged on one side in the longitudinal direction, the teeth each being limited by an outer flank and an inner flank. Here, at least one section of the tooth plate contour is shaved, where the ends of the shaved section comprise an overcut. This overcut is arranged in a low-stress area of the tooth plate contour. The invention further relates to a corresponding method for the manufacture of such a tooth plate with the pre-punching and shaving of a section of the tooth plate contour, wherein the overcut at least one end is arranged in a low-stress area of the tooth plate contour. In the subsequent normal punching of the non-shaved areas, the normally punched area of the tooth plate contour and the at least one shaved section meet in the area of the overcut at an angle to each other.
