Abstract: A method of operating a tufting machine including a sliding needle bar with a plurality of needles, a presser foot mounted slidable with the needle bar, an end yarn feed, a needle selection mechanism, a plurality of loopers, a plurality of knives to cut a loop of yarn on a respective looper, and a dislodge mechanism to selectively dislodge a loop of yarn from the looper before the yarn is cut. The method controls the feed of yarn to the needles and, when a cut end is required, a determination is made whether a predetermined yarn condition is present in the yarn at its cut end and, in response to such a determination, an additional loop of yarn, not required by the pattern data is formed, such that the additional loop of yarn forms a yarn buffer that can be pulled back through the backing medium.
