发明名称 Unvulcanized rubber member for tire manufacturing, as well as device and method for its manufacture
摘要 <p>The present invention provides an unvulcanized rubber member (12,14,16) for tire manufacturing. The member forms at least a portion of a green tire, and features: multiple rib-protrusions (30,34,38) that extend in a direction corresponding to a circumferential direction (Y) of the tire, and multiple grooves (28,32,36) that extend in a direction corresponding to a radial direction (X) of the tire and intersect the rib-protrusions. In accordance with the present invention, during vulcanization of the tire, the unvulcanized rubber member for tire manufacturing can efficiently expel air at the interior of the unvulcanized tire and between the unvulcanized tire and a vulcanizing mold. <IMAGE></p>
