Summary:A method and apparatus for piecing up a broken entwined yarn being produced on a machine from a bundle of spinning fibers and a binding thread. The bundle of spinning fibers are fed through a pair of delivery rollers into a rotating hollow spindle. The binding thread is carried on a bobbin that is, in turn, carried on the hollow spindle for being wrapped around the bundle of fibers as it passes through the hollow spindle producing an entwined yarn. Upon breaking of the entwined yarn the bundle of spinning fibers is deflected between the delivery rollers and the hollow spindle out of its normal path by a stream of suction air. An end of the entwined yarn is drawn off of a takeup bobbin and fed back through the hollow spindle and is united with an end of the binding thread. The ends of the binding thread and the entwined yarn are then twisted together with the bundle of spinning fibers and the production of the yarn is re-initiated.
