FIELD: mechanical engineering; steel wire ropes, multipurpose load-gripping devices, closed twisted rope for use as sling. SUBSTANCE: closed twisted rope is made of continuous flexible material thread. First end of thread is fastened on thread proper to form closed loop. Core of rope is wound in form of closed loop from non-closed loops. Novelty is that second end of thread is wound around core. When making the rope, flexible material in form of coil is used. First end of thread is pulled through coil and closed core is formed. Then is wound on by pulling closed core through coil. Second end of thread is twisted around core. Design versions make it possible to use different materials for making the core, make core of different configuration, wind rope from several coils. EFFECT: enhanced manufacturability and mechanization of making process, prevention of fraying of members. 23 cl, 27 dwg
