A traversing thread guide for winding a thread, comprising an elongated cam engaging portion which meshes with a helically extending endless cam groove of a traverse cylinder. A gliding member for linear to-and-fro guiding of the traversing thread guide along a rigid guide device extends parallel to the rotational axis of the traverse cylinder, said guiding member being arranged offset with respect to the center of the cam engaging portion. A thread guide member is rigidly arranged on the gliding member. The cam engaging portion comprises a base for inner radial guidance of the traversing thread guide, said base being provided with a curvature which at least approximates the curvature of the cam groove base or bottom and comprises an upper surface designed for outer radial guidance of the thread guide on an inside surface of the extended guide device. The gliding member which is rigidly connected with the cam engaging portion is provided with at least one gliding section for contacting a guide edge of the extended guide device, and which gliding section encloses an angle with the upper surface of the cam engaging portion.
