<PICT:0753615/IV(a)/1> <PICT:0753615/IV(a)/2> <PICT:0753615/IV(a)/3> <PICT:0753615/IV(a)/4> <PICT:0753615/IV(a)/5> A series of spun threads emerging fro separate and parallel discharge points are discharged into a transverse stream of liquid which carries all the threads to a place beyond the last of the discharge points, where they are drawnoff. After spinning-in and drawing off the resultant warp, the running threads may be separated and placed between individual guides above and clear of the liquid stream. Fig. 1 shows a plant for producing 72 threads, each of which passes through a group of tubes 11 containing treating liquid, as described in Specification 686,339, and emerges from one of the inclined delivery tubes 17 into the trough 16, which also receives the treating liquid issuing from tubes 17. As shown in Figs. 2 and 3, liquid is discharged into one end of trough 16 from pipe 24 and carries all the threads down the trough. The trough 16 gets wider and deeper towards the discharge end, where the threads are drawn off in warp form and pass to drying rollers 48. To prevent entanglement of the threads in the tough 16 during spinning-in, it is arranged that the threads follow parallel paths in side-by-side formation. This is achieved by making the delivery tubes 17 of progressively shorter lengths so that successive threads are laid in the trough side-by-side. This is illustrated in Fig. 2, which shows ten delivery tubes 17 laying ten threads side-by-side in the trough 16, which gets progressively wider. When the threads are all spun in and being drawn off in warp form, the running threads are lifted out of the trough and placed in comb guides 29 which are detachably mounted across the trough at intervals, after every sixth delivery tube 17. The first comb guide, which accommodates 6 threads only, is shown in Figs. 7 and 8. It comprises a tube 35 detachably mounted in brackets 31, 33 across the trough 16. At one end a series of vertical guide-rods 38 are fixed in the tube, one thread passing between each pair of adjacent rods, and rest on a tubular support 39, fixed at its ends by clips 42, 43 to tube 35. Successive comb guides are similar in construction except that the number of guide rods increases by increments of 6 until the last guide-rod accommodates all 72 threads. In operation, the first comb guide is lifted from its mounting bracket, the first six running threads are manually lifted out of the trough, the comb guide is inserted under them, each thread is positioned and the comb guide is replaced in its brackets. This is repeated with the second guide, which accommodates twelve threads, and so on until all threads are running clear of the trough.
