Abstract
An intermittent drive for a backing fabric feed is applied to a tufting machine together with a needle select apparatus, a pattern control, and a mechanism for laterally shifting a needle or the backing fabric. The intermittent drive moves the backing fabric feed in such a manner as to continuously stop the feed roller and the take-up roller over several needle stroke cycles, and to drive those rollers while the needle is not yet in the backing fabric in the first needle stroke cycle just after the stop. The pattern control provides the needle select apparatus with a signal so that of the needles can be selected and brought into the tufting engagement with the looper disposed under the laterally shifted needles to seize only one loop of pile yarn in any one of the needle stroke cycles of each periodic time of a stop and feed motion of the intermittent drive feed for the backing fabric.
