NON-UNTWISTING COILED ARTICLES MANUFACTURE METHOD Russian patent published in 2004 - IPC

FIELD: hardware and cable industry, in particular, manufacture of non-untwisting coiled articles, such as cables, ropes etc. SUBSTANCE: method involves tightening members to be coiled; coiling and squeezing said members. Members to be coiled are tightened within wire flexible zone at load making 10-20% of tensile force for each wire. After coiling and squeezing processes, article is subjected to flexure, with flexure radius being determined from formula: , where δ is diameter of wire, mm; rar is average radius of cable layer, mm; α is angle of coiling of wire into cable, deg; ε is wire tensile elongation. EFFECT: improved quality of coiled articles. 3 cl, 2 dwg
