Abstract
Traversing device in a thread winding apparatus having a housing encircling a rotatably driven cam roller which operates a traversing thread guide means mounted to project outwardly through a traverse slot or opening in the housing, with means to generate and direct an air stream to flow outwardly from said traverse slot in order to prevent the thread being wound or broken filaments thereof from entering the housing and being wrapped around the cam roller or interfering with the traversing thread guide.
