| 摘要 |
<p>The present invention relates to a vacuum-suction-type molding drum which winds and attaches a non-magnetic half-finished tire product during a molding process when a tire is manufactured. Particularly, the molding drum has enhanced attachment performance to prevent the half-finished product from escaping during a winding attachment process on the non-magnetic half-finished tire product. Nonmagnetic winding materials (3) are wound around a drum surface (2) of a drum main body (5), which rotates around a main rotational shaft (4). The drum surface (2) is joined with the drum main body (5) by double-acting cylinder rods (6). The cylinder rods (6) move up and down by pressure, generated in the drum main body (5), and vacuum and pressure, generated by a vacuum port (T) and a pressure port (P) of a direction control valve (8) in a vacuum pressure chamber (7) to expand or contract the drum surface (2) of the drum main body (5).</p> |
