Improvements in 1995 and devices to give the lengths that are identical to the various constituent strands of the stays.

摘要

In order to give identical lengths to the various strands (4) constituting a stay cable, a first "control" strand is put in place by unwinding from a roll (5), so as to extend obliquely between a raised point A and a low point B near to the roller, with a low tension; the relative level HO, with respect to the level of the point B, of a point M on the said strand is measured, which point M is situated at a given horizontal distance from the point B; the end of the said strand, located next to the roller, is cut at a well-determined point C close to the point B; then successive unwound strands are tensioned turn by turn between the two points A and B until the relative level of the point M corresponding to each of the strands is equal to the value HO of the point M of the control strand; and these successive strands are cut in turn at the point C when the above equality is satisfied. … IMAGE …
