To provide a conveyor of tire constituent members, which upgrades tire performance by eliminating an opening in the joint part of a cut-to-size breaker on a molding drum and affixes the breaker to a tire highly precisely after conveying and winding the breaker.

This conveyor of tire constituent members is used for a tire molding machine which cuts the breaker fed by a material feeder to the specified size and feeds the cut-to-size breaker to the molding drum for affixing/molding the breaker to the tire. In addition, the conveyor comprises (1) a carrying conveyor which carries the breaker and the cut-to-size breaker to the molding drum, (2) a cutting means which is installed halfway through the carrying conveyor and cuts the breaker to the specified size, (3) a bend correction means which corrects the bend at the cut end part of the breaker, (4) the carrying conveyor, and (5) a control means which controls the cutting means and the bend correction means.
