A yarn transfer device for use with a yarn windup of the type which is provided with rotatable package supports carried on chucks alternately movable into surface driven engagement with a drive roll on the windup. When actuated, the transfer device swings into engagement with a driven chuck carrying an empty support, cuts the yarn advancing to the package being doffed and threads the severed end of the feed yarn through a hollow shaft in the chuck by means of an air transport system. The severed end of yarn is centrifugally clamped in the driven chuck shaft until the centrifugal force applied drops low enough to release it to the end of the package support forming a readily accessible transfer tail thereon.
