ABSTRACT:
A plurality of helically wound tire beads are made by winding them on a forming wheel at two predetermined tension levels. The tension levels are generated by a braking pulley and magnetic particle brake in conjunction with a programmable logic controller. The first few turns of wires are made at a relatively low tension level. Subsequent turns are made at a higher tension level. The lower tension level contributes to longer life of the forming wheel assembly.
