Abstract
A method of winding a reinforcement layer of a pneumatic radial tire, which comprises providing at circumferentially spaced locations opposite to a front face of an outer peripheral surface of a building drum, a pair of traverse devices each having a fiber cord feed guide and constructed so as to be reciprocated along the axial direction of the building drum; and moving the pair of traverse devices by independent driving devices along the axial direction of the building drum while rotating the building drum, thereby simultaneously feeding rubberized fiber cords respectively from each feed device to a reinforcement belt on the building drum.
