Abstract

In connection with a device for retracting and advancing a thread processing element in relation to a threadline it is provided that the retracting and renewed advancing is caused solely by switching on a drive motor in a direction opposite its normal operational direction of rotation. For this purpose a drive member, which is maintained fixed against relative rotation in this direction of rotation, and another drive member which can be rotated in this direction of rotation in relation to the first by way of a drive motor, are provided, which change a rotating movement into an axial movement.
