"8, 9, 14-18 (German Federal Republic) The invention relates to a spindle for a ballless passage or twisting threads on ring and twisting machines equipped with spindle heads. After developing the method of balloonless threading or twisting , various proposals have been made to improve this method, which offers significant advantages over the conventional method, in which only slight improvements can be made by the use of anti-balloon rims to limit the diameter of the balloon. The main problem in extending and twisting it is closely related to the tension in the yarn, or to the place where it occurs. It sets the limits for the increase in the capacity of the commonly used slitting or twisting machines, the exceeding of which has so far been practically possible only to a slight extent. At present, in practice, spindles with specially shaped heads are recommended, or spindles with attached guide bars, the purpose of which is to improve the conditions of extending or twisting, in particular as regards the tension between the feeder and runner. The already known spindle for punching and twisting machines, equipped with heads, where the thread is guided along a screw line by means of a system of drivers, equipped with protrusions of the shape of prisms, cones, structures similar to pyramids or other, mounted in the most various ways on the spindle head. The spindle head is usually made in such a way that the thread coming out of the guide eye makes the way without being blocked and enters on it along the tangent and that the head is as rounded as possible, so that the thread runs along it without disturbances. Since the above-mentioned head protrusions are designed to take the thread and have to be shaped accordingly, they are referred to as drivers to prevent the thread from falling off the spindle head and forming a balloon. A common feature of these elements is that they are permanently installed on the spindle head and give it a strictly defined shape. The known spindle attachments, however, have the disadvantage that the lever arm protrudes relatively far,
