Abstract: In a traveling wire take-up method and machine of a wire coating line, a wire shifting guide lever of a take-up machine shifts a traveling wire toward a snagger of a bobbin holder to change over from a presently take-up bobbin to an empty bobbin. A take-up tension of the traveling wire is increased before the changeover operation, and the take-up tension of the traveling wire is reduced to a predetermined take-up tension after the changeover operation has been finished. Furthermore, increase and decrease of the take-up tension is preferably controlled by adjusting an output of a sheave motor in a dancer roller disposed in front of the take-up machine.
