IN ORDER TO GIVE IDENTICAL LENGTHS TO THE VARIOUS STRANDS (4) CONSTITUTING A STAY, BY UNWINDING FROM A COIL (6), A FIRST "REFERENCE" STRAND IS PUT INTO PLACE, EXTENDING OBLIQUELY BETWEEN A HIGH POINT A AND A LOW POINT B CLOSE TO THE COIL, WITH A REDUCED TENSION; THE RELATIVE LEVEL H0, WITH RESPECT TO THE LEVEL OF THE POINT B, OF A POINT M, OF THE SAID STRAND, LOCATED AT A GIVEN HORIZONTAL DISTANCE FROM THE POINT B, IS MEASURED; THE END, OF THE SAID STRAND, WHICH IS DISPOSED NEAR THE COIL, IS CUT AT A WELL DETERMINED POINT C CLOSE TO THE POINT B; THEN SUCCESSIVE UNWOUND STRANDS ARE STRETCHED TURN BY TURN BETWEEN THE TWO POINTS A AND B UNTIL THE RELATIVE LEVEL OF THE POINT M CORRESPONDING TO EACH OF THESE STRANDS IS EQUAL TO THE VALUE H0 OF THE POINT M OF THE REFERENCE STRAND; AND THESE SUCCESSIVE STRANDS ARE CUT IN TURN AT THE POINT C WHEN THE ABOVEMENTIONED EQUALITY IS REALIZED.(FIG. 2)
