Abstract
A tire molding apparatus folds the periphery of bead portions at a low speed with an increased pressing force. The tire molding apparatus has folding mechanisms including fingers to fold the tire component to the periphery of bead cores. Folding fingers () are integrally provided with cams (), which rotate in accordance with the swing of the fingers. The fingers () receive a driving force of a driver () through cam followers () energized by springs and the cams (), and open. The cams () are rotated in accordance with the opening of the finger, compressing the springs energizing the cam followers (). The compression of the springs reduces the opening speed of the fingers (), and increases the pressing force of finger rolls () applied to the tire component (K).
