Abstract
The apparatus for introducing a yarn or the like into the yarn catch slot of an empty bobbin tube during the changeover operation from a full bobbin to an empty bobbin at an automatic yarn winder, comprises a yarn deflector, formed of sheet metal for instance, which is provided with cutouts. Each cutout serves for deflecting an associated yarn out of an imaginary plane extending through a yarn ridge. In order to ensure that the yarn, which is still arriving at the yarn ridge of the full bobbin during the changeover operation can be infed within the imaginary plane through the yarn ridge and at the same time can extend in the plane through the yarn catch slot, the yarn is pulled by a displaceable yarn entrainment member over a curved portion of the associated cutout and deviated or deflected at the associated yarn entrainment hook.
