摘要： To provide a cable bead capable of reducing manufacturing time and harder to generate uneven twisting and a method for manufacturing the same. Specifically, there is provided a coreless ring-shaped cable bead 1 in which a single strand 2 crimped so as to have a 1 x m1 x d1 single-twisted structure or a m2 x n x d2 double-twisted structure is wound into a spiral-shaped gap part for storing (m1 - 1) or (m2 - 1) crimped strands having the above structure and is wound by m1 or m2 turns.
