Abstract
An elongated article such as a rope or cord having a series of fairings spaced apart along its length is produced in a continuous manner by the method and apparatus of the present invention. The rope comprises a core having a plurality of yarns surrounded by a layer of resilient material, and a braided jacket surrounds the core and anchors the fairings thereto. The fairings are provided by a resilient fairing yarn which is fed toward the core and which is manipulated by a needle during braiding of the jacket to cause each fairing to have a base portion anchored between the jacket and the resilient layer of the core and streamer portions extending outwardly from the base portion. The needle is mounted for reciprocation parallel to the moving core upstream of the braider, and the fairing yarn passes through the eye of the needle and a first length is displaced through the path of movement of the braid yarns into engagement with a gripping assembly located downstream of the braid yarns. The gripping assembly holds the first length of fairing yarn so that as the needle retracts, another length of braid yarn is pulled through the needle-eye. Continued operation of the braider causes the…
