Abstract: A service carriage for use with a spinning, twisting or winding frame which has a plurality of equally spaced spindles and a plurality of equally spaced work stations thereon. A compressed air system on the carriage is supplied with compressed air from a source of compressed air via a compressed air duct. The compressed air duct is fixedly arranged at each side of the frame and extends in the longitudinal direction of the frame and is connected to the compressed air source. The air duct has a plurality of automatically closing button-actuated valves which are connected in circuit therewith. Each of the valves has a closure member associated therewith. The spacing between the valves corresponds to a whole integer multiple of the spindle spacing. A plurality of coupling heads are arranged one behind the other in the direction of movement of the carriage and are mounted on a common slide member.
