The reinforced bead can be composed of a double layer, which layers are interconnected by reversed bends adjacent to the web so that the web extends into the bead. In another embodiment, the bead is a closed circular bead having portions of three layers interconnected by reversed bends adjacent to the layers of the web with the outer layer of each portion being a continuous layer.
