<p>When an unvulcanized tire is to be formed by stacking a rubber strip by a pair of rollers, the tip of the rubber strip is reliably guided to a roller for stacking and held thereon. The rubber strip (G) supplied from supply means (10) is caused to pass through between the rotating pair of rollers (21) (22) and held by the lower roller (21). The rubber strip(G) is moved to a formed body (H) on a support (2), and wound helically and stacked. When the tip of the rubber strip (G) is supplied, the rotational peripheral speed of the lower roller (21) for stacking is made relatively slower than that of the upper roller (22) to thereby provide a difference in feeding amounts of the rubber strip (G) by the rollers (21) (22), and thus the tip of the rubber strip (G) is guided to the lower roller (21) side having a smaller feeding amount. After the tip of the rubber strip (G) is held by the lower roller (21), the rotational peripheral speeds of the rollers (21) (22) are changed to the same speed, and the rubber strip (G) is stacked.</p> |
