Abstract: An overcoatable machine-made braid may be formed at high-speeds and directly from producer's low-twist, single-yarns of continuous filament, inorganic materials by this process which treats the yarn prior to or during braiding with a lubricant liquid. The treatment enables such single-yarns, which tend to be brittle, to be processed on modern high-speed braiding machines without excessive fibrillation of the yarn, duplicating overcoatable braid constructions using costlier plied twisted-pair-yarns. Additionally, the treatment enables advantage to be taken of the intrinsically greater width to depth ratio of single-yarns compared to their braid-production equivalent twisted-pair-yarns. The resulting braids are lighter in weight, have a finer hand and can be more smoothly overcoated.

Abstract: A braid, consisting of monofilaments, made of two different resins which are adapted, when heated, to fuse and mix and be subjected to polymerization or cross-linking. The braid is interposed between a thermo-retractible sleeve and conductors which are to be covered by the sleeve.
