Abstract: A spinning machine has a third guide eye rail, a third balloon-confining ring rail and a traveller ring rail each of which may be operated by a flexible member from a windless drum and the latter can have an electric motor drive. According to the invention, instead of storing all of the points defining the time course of the movement of the rail, a selected number of points such as starting points for the mean path and amplitude, one or more envelopes, and the amplitude or double amplitude of the oscillation superimposed upon the mean path are determined and a corresponding time course is generated. From the time course at given times determined by the oscillation, the maxima and minima of the path is produced by the evaluation and control unit and used to reverse the motor which raises and lowers the respective rail.

Abstract: A ring-spinning or ring-twisting machine with a ring rail having rings and travelers for each spinning or twisting spindle. The horizontal ring rail is displaceable on rigid vertical rods, the lower ends of which are connected to vertical stretches of flexible traction elements which lie substantially in the vertical plane of the weight axis of the ring rail.
