ABSTRACT:
A method and apparatus for twisting two or more strands of yarn together in accordance with a pre-selected and changeable pattern so as to obtain twisted yarn with a selected twist level extending for a selected length of the yarn and other selected twist levels and/or twist directions extending for various other lengths of the yarn so that a package of finished yarn has a variable twist pattern which is reproducible and changeable. The yarn twisting apparatus has a drive for pulling the yarn through the twist inserting apparatus, and controllable fluid twisting devices for twisting the yarn together. A programmable controller controls ratios of the speeds at which the product package drive is operated and pressures or other parameters of fluid jets effecting fluid twisting of the yarn. The programmable controller can also vary the time that each selected ratio is maintained.
