Spinning and winding of yarns

An apparatus for continuously spinning and subsequently winding yarn which comprises at least one yarn-spinning means, yarn-winding means for receiving and winding the spun yarn, yarn storage means located between said spinning means and said winding means, means adapted to selectively feed yarn to and from said storage means, adjustable control means located between said spinning means and said winding means adapted to govern the rate of removal of yarn from said yarn storage means, means for detecting a fault in the yarn disposed in the path of said yarn passing from said yarn-spinning means to said storage means, yarn-marking means actuated by the fault-detecting means and located adjacent said yarn path and adapted to mark the yarn adjacent the detected fault, means sensitive to the mark made by said fault-detecting means disposed adjacent said yarn path, a yarn knotter and cooperating thread clamp actuated by the sensitive means upon sensing a mark made by said fault-detecting means, said knotter and clamp joining yarn portions adjacent the yarn portion containing said fault, and means for engaging and removing the yarn fault-containing portion from the joined yarn portions after actuation of said knotter and clamp.
