    • A reinforced blade (130, 330, 430) for use in a tire vulcanization mold (100, 300, 400) is provided. The reinforced blade (130, 330, 430), having a thickness (t) of less than 0.030 inches, is configured to form a sipe (620, 720) in a tread (600, 700) of a tire in the tire vulcanization mold (100, 300, 400). The reinforced blade (130, 330, 430) includes a main segment (135, 335, 435) and a support segment (150, 350, 450A) extending from at least one end portion (145, 352, 445) of the main segment (135, 335, 435) of the reinforced blade (130, 330, 430) and configured to support the at least one end portion (145, 352, 445) of the main segment (135, 335, 435) of the reinforced blade (130, 330, 430) in the mold (100, 300, 400) during vulcanization.
    • 提供了一种用于轮胎硫化模具(100,300,400)中的加强刀片(130,330,430)。 具有厚度(t)小于0.030英寸的加强刀片(130,330,430)构造成在轮胎硫化模具中的轮胎的胎面(600,700)中形成刀槽花纹(620,720) (100,300,400)。 加强刀片(130,330,430)包括主段(135,335,435)和从主段的至少一个端部(145,352,445)延伸的支撑段(150,350,450A) (135,335,435),并且构造成支撑所述加强叶片(130,330,430)的所述主段(135,335,435)的所述至少一个端部(145,335,435) (130,330,430)在硫化期间在模具(100,300,400)中。
