Abstract
A method is provided for making an annular reinforcement structure having inner and outer reinforcement bands maintained in concentric alignment by a resilient spacing element positioned between the bands. The method includes the steps of placing the spacing element against the inside face of the outer reinforcement band and compressing the spacing element with a jig, adjacent the top edge of the outer reinforcement band. The spacing element is sufficiently compressed to allow the inner reinforcement band to slide into concentric alignment with the outer reinforcement band, with a minimum of deflection and/or distortion of the inner reinforcement band.
