Abstract (en)
[origin: WO2019122698A1] The present invention relates to a method for producing a wire element (1) by interlacing at least a first strand (2) and a second strand (3), during which strand tension control is effected by: defining an assembly tension set point (T set), representative of a state of longitudinal tension to be obtained in the first strand (2) when said first strand reaches the assembly point (4); measuring the actual assembly tension (T actual) applied in the first strand, said measurement being taken at a first tension measurement point (PT1) located along the first strand and upstream of the assembly point (4); and operating a tension regulating member (34), such as a capstan, which acts on the first strand (2) upstream of the assembly point (4) such as to cause the actual assembly tension (T_actual) within said first strand to converge automatically towards the assembly tension set point (T_set).
