The present invention relates to a steel cord for reinforcing tire belt plies, comprising a cord formed by periodically twisting n wires, wherein: the n wires are compressed by rolling, the wires are compressed by rolling such that at least one of the n wires is compressed into a non-circular shape; and if n is an odd number, the cross-section of one wire from among the n wires becomes circular and the cross-section of n-1 wires becomes non-circular by rolling, and if n is an even number, the cross-section of two wires from among the n wires becomes circular and the cross-section of n-2 wires becomes non-circular by rolling.

    La présente invention concerne un câblé d'acier destiné au renforcement de nappes de bande de pneumatique, comprenant un câblé formé par torsion périodique de n fils, les n fils étant comprimés par laminage, les fils étant comprimés par laminage de telle sorte qu'au moins l'un des n fils est comprimé en une forme non circulaire ; et si n est un nombre impair, la section transversale d'un fil parmi les n fils devenant circulaire et la section transversale de n - 1 fils devenant non circulaire par laminage, et si n est un nombre pair, la section transversale de deux fils parmi les n fils devenant circulaire et la section transversale de n - 2 fils devenant non circulaire par laminage.

    본 발명은 타이어 벨트 플라이 보강용 스틸코드에 관한 것으로, n 개의 소선이 주기적으로 꼬여서 형성된 코드;를 포함하며, n 개의 상기 소선은 압연가공에 의해 압착되며, 압연가공에 의해 상기 소선은 압착되어 n개의 소선 중 적어도 하나 이상은 비원형으로 압축되며, n이 홀수일 때, 압연가공에 의해 n 개의 소선 중 1개의 소선의 단면은 원형이 되고, n-1 개의 소선의 단면은 비원형이되며, n이 짝수일 때, 압연가공에 의해 n 개의 소선 중 2개의 소선의 단면은 원형이 되고, n-2 개의 소선의 단면은 비원형이되는 것을 특징으로 하는 것이다.
