  • Patent number: 8375761
    Abstract: A method and a device for producing an internally or externally toothed cup-shaped (body) sheet material component with alternating teeth and grooves that run in parallel to the center axis of the cup, especially of a clutch plate carrier. The method and device allow the use of profile rollers, the rollers controlling the true running, dimensional accuracy and the surface of the cup-shaped sheet material component having an internally and externally profiled wall in the shape of teeth, in such a manner that they guarantee a specifically variable position during production. An untoothed cup-shaped sheet material component is slid onto a pick-up mandrel which has an external toothing corresponding to the internal toothing of the sheet material component to be produced and the external profile is then rolled onto the cup-shaped sheet material component by pressing the cup-shaped sheet material component together with the pick-up mandrel by means of a set of profile rollers while exerting a radial pressure.
