Abstract
A traversing yarn guide ( ) that is moved back and forth produces cross winding of yarn on a bobbin at each winding head of a textile spinning or winding machine in order to wind cross-wound bobbins. After a yarn interruption, an auxiliary yarn guide ( ) in an active position keeps the yarn in a position that is raised out of the traversing yarn guide ( ). In a rest position ( ), the auxiliary yarn guide ( ) does not influence the yarn and the traversing yarn guide ( ) can grasp and take the yarn to be wound from the auxiliary yarn guide ( ). In order to assure a reliable insertion of the yarn ( ) into the traversing yarn guide ( ) and to assure its correct grasping of the yarn ( ), the yarn ( ) assumes an initial position within the traversing range after the yarn interruption, which position is set by the auxiliary yarn guide ( ) in the active position, before the yarn ( ) is lowered into the stationary traversing yarn guide ( ) by a position change of the auxiliary yarn guide ( ) into the rest position ( ).
