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 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 rotating a finished package of twisted yarn, a yarn twister for twisting the yarn together, and a drive for the yarn twister. Each drive includes a motor which may be a servo motor or a controllable a.c. motor so that the product package drive and the yarn twisting drive may be controlled to selected speed ratios, and also includes a programmable controller for controlling this ratio and for varying the time that each selected ratio is maintained.
