NOVELTY - The process involves applying tension to the strength element (7). The tension on the strength element is maintained after applying tension to the strength element. A combination of the tension and the heat for strength element are selected to cause creep of those filaments of the strength element that are the filaments that are able to be creeped. A desired amount of elongation of the strength element is detected. The strength element is cooled while maintaining tension on the strength element.    USE - Process for forming synthetic ropes such as tow rope, towing warp, trawl warp, deep sea lowering and lifting rope, powered block rigged mooring rope, powered block rigged oil derrick anchoring rope used with blocks and also with powered block, superwide and paravane line used in seismic surveillance used with towed array, yachting rope, rigging rope for pleasure craft, sail craft, running rigging, powered block rigged anchor rope and drag line.    ADVANTAGE - In the case of increased strength, the increase in strength is important both to decrease costs of raw materials and production process, costs of rigging equipment needed to carry, lift, stabilize and stably float and sustain and support the weight of the ropes, as well to decrease drag in water and drag in air of such ropes. The process provides for a high strength synthetic strength element containing rope capable of being used with powered blocks that exhibits both improved strength as well as improved strength retention over time and improved longevity. The synthetic rope for use with powered blocks light weight compared to steel wire cable coupled with its improved strength, improved strength retention over time and improved longevity, it possesses the advantages of being more buoyant in water than steel wire cable while also being capable of enduring the rigors of use in any of the mentioned applications of use for a longer duration than steel wire cable. The use of a long oven having many capstans accommodates a very long length of the strength element and turning at varying speeds and rates of rotation so as to maintain the tension on differing portions of the strength element located between different capstans, and thus by extension on the filaments forming the strength element as well as on the thermoplastic core also forming the strength element is highly useful, especially for permitting an endless flow production process.
