<PICT:0696365/IV (a)/1> <PICT:0696365/IV (a)/2> <PICT:0696365/IV (a)/3> <PICT:0696365/IV (a)/4> <PICT:0696365/IV (a)/5> In a spinning machine for artificial fibres in which liquid is played on to a thread passing along a thread-advancing device from a liquid outlet tube projecting from a supply pipe through a gland, the outlet tube has an inlet which can, when required, be sealed temporarily by moving the tube relatively to the gland. The outlet tube preferably consists of a straight horizontal tube which may be moved lengthwise in relation to the gland in order to control the flow of liquid through the tube, and in one of these forms the tube is pulled outward, when the liquid is required to flow. The outlet tube in this case is so located that, even when it is in its outward position, it does not project into the zone vertically above the thread in the thread-advancing device, the liquid issuing from the end of the outlet tube under sufficient pressure to enter the zone in question and thus play on to the thread passing along the thread-advancing device. In one modification an outlet tube 5 (Fig. 2) having an outlet 10 and permanently closed at its inner end 11 fits snugly but slidably in the central hole 9 of the solid rubber gland 7 inserted in a supply pipe 8. The tube 5 has a side inlet 12 which is normally exposed within the supply pipe 8 but which is temporarily sealed when the outlet tube 5 is moved lengthwise to the right in the gland 7. In an alternative construction the flanged gland 23 (Figs. 3, 4 and 5) has an axial hole 25 in which a flanged outlet tube 26 fits snugly. The inner end 30 of the tube 26 projects into the supply pipe and is permanently closed. The tube 26 has a side inlet 31 which, when the outer portion 27 of the tube is vertically down, communicates with the channel 32, the inner end of which communicates with the supply pipe. The side inlet 31 is sealed temporarily by rotating the tube 26 relative to the gland 23. More than one side inlet can be provided in the tube 26 so that by rotating the latter one or more of the inlets can be brought into communication with the channel 32 or with additional channels cut in the gland 23. In a third alternative construction a hole 22 (Fig. 8) in the wall 21 of a supply pipe is fitted with a gland 23 which has a central bore 33 open at the outer end 34 but closed at the inner end 35. The bore 33 communicates with the supply pipe via a longitudinal channel 37 cut in the circumference of the gland 23 and a radial channel 36, which with the bore 33 forms a T-shaped channel. An outlet tube 38 open at both its inner end 39 and its outer end fits snugly but slidably in the bore 33. As shown, liquid from the supply pipe is free to flow through channels 37 and 36, bore 33 and outlet tube 38, but the flow can be stopped by pushing tube 38 into the bore 33 until its inner end 39 has passed beyond the channel 36.
