Abstract
A metal cord has cylindrical layers formed of an internal layer, an intermediate layer, and an external layer. The in internal layer includes M threads. The intermediate layer includes N threads wound in a helix around the internal layer. The external layer includes P threads wound in a helix around the intermediate layer. An inter-thread distance, D2, between the threads of the intermediate layer is greater than or equal to 25 μm. An inter-thread distance, D3, between the threads of the external layer is greater than or equal to 25 μm.
