The invention provides a bead member which is capable of suppressing the projection of the winding start end and the winding finish end of the bead wire and is further excellent in the adhesiveness between the bead core and the bead filler. The bead member manufacturing method in the present invention includes a bead core forming step of winding and stacking a bead wire (6) from a winding start end (R1) to a winding finish end (R2) and forming a bead core (5) having an annular shape, the bead wire (6) being formed by coating an outer circumferential surface of a metal wire with a topping rubber; and a bead wire banding step of winding a tape-shaped rubber (7) around one or both of the winding start end (R1) and the winding finish end (R2), wherein tackiness of the tape-shaped rubber (7) ishigher than tackiness of the topping rubber.

    本发明提供一种胎圈部件,该胎圈部件可以抑制胎圈钢丝的卷绕起始端部或卷绕终止端部的冒出,并且胎圈芯和胎边芯之间的密合性呈优异。本发明的胎圈部件的制造方法具备:胎圈芯形成工序,在该工序中,将在金属丝的外周面被覆有上层橡胶的胎圈钢丝(6)从卷绕起始端部(R1)叠绕至卷绕终止端部(R2)为止,来形成圆环状的胎圈芯(5);以及胎圈钢丝捆扎工序,在该工序中,在卷绕起始端部(R1)和卷绕终止端部(R2)的一个端部或两个端部缠绕带状橡胶(7),带状橡胶(7)的胶粘性比上层橡胶的胶粘性高。
