Abstract

Low carbon steel strip or plate is used for each rim composed of a base portion having a gutter for receiving a split lockring extending round one end and a fixed tyre bead retaining flange round the other. The method comprises bending a steel strip of uniform predetermined thickness into the form of a circle and butt welding the contiguous axial edges to form a cylinder. Then cold working the cylinder in order to conform the dia. and dimensions to subsequent operational requirements and simultaneously to flare one end of the cylinder to form the rim gutter, heating the flared gutter portion and subjecting the heated portion to compressive load in order to form the vertical wall of the gutter flange and increase the thickness of both the wall and the radial corner of the gutter.
