Abstract
Improper actuation of a hanger for bobbins and bobbin core sleeves on a yarn-producing machine as a result of failure of the sleeve to seat properly at a spindle, is prevented by providing hangers with switching sleeves so that these can only be operated by a spindle shaft upon full insertion of the spindle into the roving sleeve.
