Abstract: Disclosed is a method of making a rim having hollow flanges formed on its opposite annular edges. It comprises the steps of: cutting an elongated metal band of a fixed width to provide metal strips of a predetermined length; rolling a selected metal strip into a ring; welding the opposite ends of the ring; curling each annular edge of the ring outward; and roll-forming the main annular part to define a well along the center line of the main annular part. The method further comprises the steps of: bending the opposite bead areas toward the center well; closing the gap between each curl edge and the counter bead area; and unbending the opposite bead areas into the final rim shape.

Abstract: A deep V-section aero rim for a tensioned spoke wheel and a method for producing it are disclosed. The rim is produced by extruding an alloy to produce a rim profile, rolling the extrusion, cutting the rolled extrusion to length, joining the free ends to produce a rim blank and mechanically reducing the thickness of the rim side walls a substantial amount. In one embodiment, each of the side walls, after extrusion, has a thickness that is sufficient to withstand buckling of the side walls during rolling. After rolling and cutting the extrusion to length, its ends are joined and each side wall, namely, the portion between the rim floor and the braking surface, is thinned, preferably by mechanical abrasion, until each side wall is so thin that an extrusion having side walls of that thickness could not be rolled without side wall buckling. In another embodiment, flanges on the outside of the side walls prevent buckling during rolling and the flanges are removed after rolling.

Abstract: A bead wire for a bead core of a tire, having at least one portion of its annular extent formed from a material having characteristics of superelasticity, resulting in increasing deformations of the bead core when a constant stretching load is applied at constant temperature. As the load ceases, the bead core recovers from the deformation. The characteristics of the bead core allow mounting a tire incorporating the bead core to a rim at ambient temperature, with intelligent adjustment of the bead core to the dimensions of the seat of the rim. The bead core increases the magnitude of an inward contraction stress as its temperature increases, so that it increases the gripping pressure exerted by the tire beads on the rim when the tire runs in the deflated state.
