ABSTRACT:
A method is used for producing reinforcing members preferably used in tires. The method comprises steps of causing cords to pass through a plurality of small apertures of a guide plate each for one of the cords to arrange these cords in a predetermined positional relation, winding the cords about winding type braking means, and extending the cords about a dancer roller. Thereafter, the cords are caused to pass through a plurality of small apertures of a movable guide plate each for one of the cords. The movable guide plate is reciprocatively moved in horizontal directions perpendicular to advancing directions of the cords so that the cords are reciprocatively moved onto a calender for rubber coating provided closely adjacent the movable guide plate to embrace the cords in the form of waves between rubber sheets and coat the cords by the rubber sheets, thereby obtaining the reinforcing member. Shapes of the waves of the cords can be modified by changing traverse distances of the movable guide plate and relative speeds between rotating speeds of the calender and reciprocatively moving speeds of the movable guide plate.
