Thread Traversing Device for a Winding Device of a Textile Machine Producing Cross-Wound Bobbins

Abstract

This invention relates to a thread traversing device for a winding device of a cross-wound bobbin producing textile machine. Said thread traversing device has a thread guide which is guided in a thread guide rod in the working area and is connected to an individual drive mechanism by a continuous traction mechanism. According to the invention, the thread traversing device ( 11 ) has a substantially closed housing ( 23 ,) whose inner space ( 37 ) in the traversing area (B) of the thread guide ( 25 ) is sealed by the continuous traction mechanism ( 30 ).
