发明名称 Method and apparatus for winding cross-wound bobbins driven in a rotary manner
摘要 A traversing yarn guide (5) 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 (4) in an active position keeps the yarn in a position that is raised out of the traversing yarn guide (5). In a rest position (40'), the auxiliary yarn guide (4) does not influence the yarn and the traversing yarn guide (5) can grasp and take the yarn to be wound from the auxiliary yarn guide (4). In order to assure a reliable insertion of the yarn (3) into the traversing yarn guide (5) and to assure its correct grasping of the yarn (3), the yarn (3) assumes an initial position within the traversing range after the yarn interruption, which position is set by the auxiliary yarn guide (4) in the active position, before the yarn (3) is lowered into the stationary traversing yarn guide (5) by a position change of the auxiliary yarn guide (4) into the rest position (4').
