Provided are a tread rubber forming method and a tread rubber forming apparatus capable of effectively forming a tread rubber including a conductive layer and a three-layer rubber layer in a seamless manner. The tread rubber forming method (S1) includes a first step for forming a base layer (1); a second step for forming a first intermediate layer (21) on a portion of the outer peripheral surface of the base layer (1); a third step (S13) for forming a first cover layer (31) by laminating and winding a third rubber strip (GS3) on the outer peripheral surface of the first intermediate layer (21); a fourth step (S14) for forming a conductive layer (4) by winding a conductive fourth rubber strip (GS4) over the outer peripheral surface of the first cover layer (31) from a position in contact with the base layer (1); and a fifth step in which a second cover layer (32) is formed on the outside in the radial direction of the base layer (1) such that a portion of the conductive layer (4) is exposed on the outside in the radial direction of the tread rubber.

    提供胎面胶形成方法和胎面胶形成装置,其能够以无接缝的方式有效地形成包含导电层和三层的橡胶层的胎面胶。胎面胶形成方法(S1)包含:第一工序,其形成基层(1);第二工序,其在基层(1)的外周面的局部形成第一中间层(21);第三工序(S13),其将第三橡胶条(GS3)层叠卷绕在第一中间层(21)的外周面,由此形成第一覆盖层(31);第四工序(S14),其将导电性的第四橡胶条(GS4)从与基层(1)相接的位置起遍及第一覆盖层(31)的外周面地卷绕,形成导电层(4);以及第五工序,其以导电层(4)的局部露出于胎面胶的径向外侧的方式在基层(1)的径向外侧形成第二覆盖层(32)。
