Abstract
A faired article comprising a cable having a core surrounded by a braided jacket is provided with at least one row of fairing loops extending lengthwise of the jacket for the purpose of reducing strumming, drag and cable fatigue when the cable is installed underwater. The faired article is manufactured by guiding a length of fairing yarn into proximity with the upstream side of the ring of a braider, entraining the fairing yarn in an air stream directed across the path of movement of the braid yarns inside the braider ring, and causing the fairing yarn entrained therein to pass through the path of movement of the braid yarns as they advance around the braider ring, thereby enabling the braid yarns to form the fairing yarn into loops as the braid yarns form the jacket around the core. Preferred apparatus for practicing the method of the present invention is also disclosed.
