Abstract

PURPOSE:To make it possible to prevent disconnection of an optical fiber without inversion when a wire is twisted by specifying the ratio between the central value of a width and the height of each molding wire and heteromorphic wire. CONSTITUTION:The ratio A (A=W/T) between the central value W of the width and the height T of each molding wire and heteromorphic wire is set to 1.0-1.4 for the molding wire and 1.3-1.8 for the heteromorphic wire. Provided W is shown in the formula W=(D+T+2c)pi/n, where D: the diameter of an optical fiber unit, c: the gap between an optical fiber unit and in aluminum coated steel wire, n: twisted number, and pi: number pi. The molding wire is supplied to a twister in the state before forming, that is, that where a round type aluminum wire 1b is wound around a steel wire 1a composed of a round wire, is sectorally formed at a stranding part by formation rolls 11 and 12, and then is twisted on an OP unit. In this case, stable twisting wire can be made without problems in forming when the formula 1.0<=W/T<=1.4 is set.
