Abstract
The thread guide arrangement for ring spinning and ring twisting machines comprises a thread guide lappet (6) and a wire-shaped thread guide eyelet (3), defining the thread balloon point, and mounted using a screw (13), which screw (13) is provided with an extension (13a) acting as a thread catching device, and which thus prevents the occurrence of multiple end breakages in a row. For easier removal of thread remnants, the extension (13a) can be smooth. The screw (13) furthermore is used for centerably mounting the thread guide eyelet (3) with respect to the spindle axis (a).
