Abstract:
A profiled vehicle wheel rim is manufactured by spirally winding a continuous strip of ductile sheet metal onto a profiled former, with an adhesive interposed between the turns, under forces which deform the strip from the flat state to adopt the shape of the former. In a preferred construction a disc for the wheel is interposed between two axially separable parts of the former so that the windings bend down over the axial extremities of the periphery of the disc, thus entrapping it in an annular channel of the formed rim.
