The reinforcing strand (400) comprises a core (403) around which steel filaments (404) are twisted with the same final lay length and direction. The steel filaments are arranged in an intermediate layer comprising N first steel filaments and in an outer layer of 2N steel filaments arranged circumferentially around the intermediate layer. In the intermediate layer, the filaments will be in contact with each other at a closed lay length determined by the number N of steel filaments in the intermediate layer, the diameter of the core, and the diameter of the first steel filament. By selecting a final lay length and direction equal to between two and six times the closed lay length, a gap will be formed between the intermediate layer monofilaments. The 2N outer layer monofilaments are further divided into a smaller diameter steel monofilament group (408) and a larger diameter steel monofilament group (406).

    增强股(400)包括芯(403),钢单丝(404)以相同的最终捻距长度和方向围绕该芯捻合。钢单丝布置在包括N个第一钢单丝的中间层中以及周向地围绕中间层布置的2N个钢单丝的外层中。在中间层中,单丝将以闭合捻距长度彼此接触,闭合捻距长度由中间层中的钢单丝数目N、芯的直径以及第一钢单丝的直径确定。通过选择等于闭合捻距长度两倍到六倍之间的最终捻距长度和方向,将在中间层单丝之间形成间隙。2N个外层单丝被进一步划分为较小直径钢单丝组(408)和较大直径钢单丝组(406)。
