PROBLEM TO BE SOLVED: To surely guide and hold the tip part of a rubber strip to rollers for lamination when laminating the rubber strip by a pair of rollers to form an unvulcanized tire. SOLUTION: The rubber strip G supplied from a supply means 10 is passed between the pair of rotating rollers 21, 22, held by the lower roller 21, moved to a molded body H on a support body 2 and spirally wound and laminated. When supplying the tip of the rubber strip G, the rotating peripheral speed of the lower roller 21 for lamination is made slow relative to that of the upper roller 22 to provide a difference in the feed quantity of the rubber strip G by the respective rollers 21, 22, and the tip part of the rubber strip G is guided to the lower roller 21 side less in the feed quantity. After holding the tip part of the rubber strip G by the lower roller 21, the rotating peripheral speeds of the rollers 21, 22 are changed to the same speed to laminate the rubber strip G.
