tire industry; radial-ply tires. SUBSTANCE: layers of single-strand polyamide cord of low twist and low thread density are placed over metal cord layers of breaker in pneumatic tire casing. Width of lower textile layer exceeds width of metal cord layers being applied to cover their edges. Width of upper layer is smaller and it is applied to lower layer to form smooth step-like transfer from metal cord layers to tread. EFFECT: increased reliability and safety of tire. |
