<p>Safety ropes, according to this invention, are made in two main embodiments. According to the first embodiment, there are one or more auxiliary strands (2, 7, 13) beside the main strands (3, 5, 6, 9-12), of larger stretching coefficient. When the rope (1, 4, 8) breaks, those strands (2, 7, 13) break last, and in this way prevent a jerk and a strike that would be caused by broken ends of the main strands (3, 5, 6, 9-12). The auxiliary strand can be interlaced with the main strands in several different ways. According to the other embodiment, a double loop (14) is made consisting of the main rope (15) that is twisted in loops (16, 17) at the ends. Parallel with the main rope (15), a longer and thinner auxiliary rope (18) is interlaced by knots (19). The auxiliary rope (18) will, when the main rope (15) is overloaded and breaks, break last and in that way soothe the strike, which could cause an accident. Double loops are connected at the ends of the main ropes for mooring of ships and other mobile objects.</p> |
