As a result of the opposite lay, the torques which occur in the layers of strands when under load cancel each other out and a non-twisting rope structure is achieved. An elastic intersheath is positioned between the oppositely laid layers of strands to protect the strands against abrasion and to transmit the torque over a wide area in the rope.
BACKGROUND OF THE INVENTION The present invention relates to a synthetic fiber rope, preferably of aromatic polyamide.
SUMMARY OF THE INVENTION An objective of the present invention is to avoid the disadvantages of the known synthetic fiber rope and to propose a synthetic fiber rope with a non-twisting structure.
DESCRIPTION OF TIE PREFERRED EMBODIMENT FIG. 1 shows a schematic representation of an elevator installation with a 2:1 roping arrangement over two return pulleys 2 and 3. With this arrangement, rope end connectors 4 for a traction rope 1 are not fastened to a car 5 and a counterweight 6 but in each case to the top end of a hoistway 7. The reversal at the two return pulleys 2 and 3 and at a traction sheave 8 of the traction rope 1 which is loaded with the car 5 and counterweight 6 can be clearly seen. FIG. 2 shows a first embodiment of the traction rope 1 according to the invention. Strands 9, 10, 11 and 12 for use in the elevator rope 1 are twisted or laid from individual aramide fibers. To protect the fibers, each individual aramide fiber, as well as the strands 9, 10, 11 and 12 themselves, is treated with an impregnating substance, e.g. polyurethane solution. Depending on the reverse bending performance required, the proportion of polyurethane can be between ten and sixty percent.
