ABSTRACT:
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 transport mechanism that revolves it about its axis of symmetry while a reel of filaform material is orbited about an axis tangent to a fixed reference line perpendicular to the orbit axis. Thus, the filaform material is wrapped around the core ring 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 preceding convolution.
