Abstract
A method and apparatus for feeding yarn to a knitting machine having needle selecting means so that the length of yarn required to be knitted into each sequence of a small number of stitches is not constant. The length of yarn as actually fed to the knitting machine during each sequence of a small number of stitches is measured, and a value or signal representing the actual measured length of yarn is then compared to a predetermined length value which represents or is a function of a predetermined stitch length. The tension in the yarn as fed to the knitting machine is continuously adjusted in response to deviations or differences detected by the comparison of the predetermined and measured length values.
