The upward movements of the ring rail 7 of a spinning machine are effected by hydraulic pressure in a single-acting motor 17 acting through belts 12, 9 under control of a valve 24 which controls the pressure in the outlet 23 of a constant delivery pump 20 by the relief of pressure through a return pipe 22. The downward movements are effected by gravity. The normal reciprocating movement of the rail is obtained by a cam 37 acting on valve 24 through belts 27a, 27b, with a follow-up from the rail via a roller 32 acting on one end of the belts. The successive offsets of height of the rail is obtained by a drum 28 acting upon the end of belt 27a. The hydraulic control circuit also includes electromagnetic valves 40, 41 and 43, a pressure relief valve 46 and a check valve 48. The valve 40 is adapted to close outlet 23 to valve 24 so that a rapid build-up of pressure in motor 17 can be obtained for a quick upward movement of the rail. Valve 43 supplies pressure to a motor 39 to release the machine brake F. Valve 41 is opened for a quick release of pressure and a quick downward movement of the rail. These valves are operated for initial and final larger movements of the ring rail in the build-up of a cop.
