ABSTRACT:
A method for producing a wheel pan includes cold-rolling a rectangular metal strip of a given uniform thickness by conical rolls into a semicircular ring, such that the thickness reduction on the outer edge of the curved strip is at least 20%, and the circumference of the semicircular ring thus produced extends 130-310°, preferably 180°; bending the semicircular ring into a complete circle to produce a conical hoop, welding the ends together; and shaping the hoop to form the bottom of the pan.
