Abstract
Abstract A high-strength rope, strand or yarn includes a core component, such as a fiber or a plurality thereof, of elastic synthetic plastic material, the core component having a predetermined length. A plurality of envelope components surrounds the core component and includes filaments of high tensile strength synthetic plastic material, the filaments being of substantially equal length exceeding the predetermined length. The envelope components may be in form of strands or yarns, each including a plurality of high tensile strength filaments. The rope may be soaked with flexible wear-resistant material, and a jacket of flexible, wear-resistant synthetic plastic material may surround the rope or the strands, yarns or filaments which constitute the same.
