PROBLEM TO BE SOLVED: To provide a ribbon-shaped rubber rolling and bonding apparatus which is used in a tire molding method for spirally winding the ribbon-shaped rubber extruded from an extruder around a rotary support to attach a rubber member having a predetermined cross section to the support and equipped with a pair of opposed rollers which have rolling surfaces for allowing the ribbon-shaped rubber to pass through the nip between the rollers to specify the cross-sectional shape of the ribbon-shaped rubber and constituted so that the rolling surface of one roller functions as a surface for rolling the passed ribbon-shaped rubber to bond the same to the support, and to certainly hold the ribbon-shaped rubber passed through the nip between the rollers to the rolling surface of one roller and to prevent air from entering the gap between the ribbon-shaped rubber and the support when the ribbon-shaped rubber is bonded to the support to prevent the damage of the mutual adhesion of the ribbon-shaped rubber and the support. SOLUTION: The rolling surface of one roller is formed so as to have a protruded cross-sectional shape while the rolling surface of the other roller is formed into a recessed cross sectional shape.
