Abstract

PURPOSE:To enhance separation resistance in a steel cord as a carcass cord turned up around a bead core by setting an angle with respect to the radial direction of its tyre in a specific range. CONSTITUTION:A steel cord 1 used as a carcass cord is turned up around a bead core 2. In this case, the steel cord 1 from the turn up portion of the bead core 2 to its end portion is turned up not in parallel with the radial direction of a tyre but with a defined angle alpha. The angle alpha of the steel cord 1 with respect to the radial direction of the tyre is set in 5-45 deg. range. With this arrangement, repeated stress F in the radial direction can be divided into stress F1 in the carcass cord direction (F1<F) and stress F3 in the direction which is vertical to the carcass cord direction so that separation resistance can be enhanced.
