Abstract

A yarn winding machine for winding a continuously advancing yarn into packages, the yarn being guided in a yarn traversing mechanism which includes a traversing unit and a grooved roll downstream thereof in the direction of the advance of the yarn. To transfer the yarn from a full package mounted on one winding spindle to an empty tube mounted on another winding spindle, the spindle mounting the full yarn package is moved to a doffing position and the spindle mounting the empty winding tube is moved to the winding position. The machine is provided with a yarn deflection device, which comprises a guide plate extending parallel to the circumference of the grooved roll, and a yarn guide adapted for movement in a direction parallel to the winding spindles. By rotating the guide plate, the yarn can be removed from the traversing mechanism without significantly changing its looping, and the yarn guide is then adapted to engage the advancing yarn and move the yarn into engagement with a yarn catching slot on the empty winding tube.
