With reference to a rope of load-bearing aramide fiber strands (9, 10, 11) laid parallel to each other in concentric layers of strands (14, 16), it is proposed to lay the strands (12) of an outermost layer of strands (12) with opposite lay to the rope core (19). As a result of the opposite lay, the torques which occur in the layers of strands (14, 16, 21) when under load cancel each other out; a non-twisting rope structure is achieved. An elastic intersheath (20) between the oppositely laid layers of strands (16, 21) serves to protect the strands (10, 11, 12) against abrasion and to transmit the torque over a wide area in the elevator rope (1). |
