An apparatus and method for continuously winding a high speed running yarn are provided, and wherein empty bobbins are serially delivered to a winding position and the full bobbins are laterally moved from the winding position to a doffing position. An automatic yarn changeover mechanism is provided for transferring the running yarn from the full bobbin onto an empty bobbin which is brought to the winding position, and such that there is no yarn stoppage or loss of yarn during the changeover procedure. As part of the changeover procedure, the yarn is severed, with the severed end running onto the rotating full bobbin. In order to prevent this severed yarn end from contacting and becoming entangled in the closely adjacent empty bobbin then being wound at the winding position, there is provided air jet means which is operative during the changeover procedure to direct an airstream onto the surface of the rotating full bobbin to restrain the outward radial movement of the severed yarn end, with the airstream continuing until the full bobbin ceases to rotate.
