摘要：In replacing a completed yarn package by an empty bobbin tube in a yarn processing machine, the running yarn delivered to the completed yarn package is severed, the severed yarn is delivered to a yarn collection zone, the running yarn is engaged with an empty bobbin tube without halting delivery of the yarn from the yarn collection zone, the completed yarn package is removed from a bobbin tube support and replaced by the yarn engaged with the empty bobbin tube while the yarn continues to be delivered to the yarn collection zone, and the empty bobbin is rotated to wind on yarn delivered to it to form a package thereon. While the running yarn is delivered to the yarn collection zone and before the empty bobbin tube is placed on the support, the yarn is so engaged with the bobbin tube that the running yarn is permitted to continue to pass to the yarn collection zone before and after the bobbin tube has been placed on the support and without rotation thereof and is so engaged that when the bobbin tube rotates the running yarn is constrained to rotate therewith to commence winding of the running on the tube. A reserve winding may be formed at one end of the empty bobbin from yarn withdrawn from the yarn collection zone.
