ABSTRACT:
A method and apparatus for automatically adjusting the tensile force ratio between axially moving outer and inner threads of cabled yarn during manufacture of such yarn in a cabling machine in which the actual tensile force ratio is measured in the region of the thread guide eye of the cabling machine, such measured tensile force ratio is compared with a desired tensile force ratio and the thread guide eye of the cabling machine is axially adjusted to provide a desired height of the thread balloon in the yarn cabling machine to provide a desired outer and inner thread tensile force ratio. Suitable apparatus, preferably in the form of a hand held instrument is provided for automatically performing such adjustment of the tensile force ratio.
