In a yarn winding textile machine, with a main hydraulic control circuit that causes reciprocation of a ring rail, there is associated a hydraulic emergency resetting circuit which includes a solenoid valve also forming part of the main circuit and a hydraulic pressure accumulator. The resetting circuit is connected in such a manner to the hydraulic motor of the main control circuit that upon electric power failure the solenoid valve is automatically switched, causing the hydraulic pressure from the pressure accumulator to rapidly move said hydraulic motor and thus said rail into a position where no normal yarn winding may take place.
