A method and machine for making wire beads for tires wherein the beads comprise one or more wire filaments helically wrapped around a solid metal core ring. The metal core ring is of circular cross section and is supported in a holding mechanism that includes inner and outer endless belts which revolve the core ring about its axis of symmetry while at least one length of filaform material is wrapped around it in a helical path about the circular axis defined by the center of the core ring cross section. The pitch of the helical wrap is adjusted to place each convolution of the filament in a predetermined spaced relation to the next preceeding convolution. Thus, a plurality of convolutions are provided on the core ring with a single filament.
