Abstract

<PICT:0481777/IV/1> Artificial filaments and the like are produced by extruding viscous material, such as viscose, into a precipitating bath and leading the thread or bundle of threads from the nozzles over a guide, round two or more godets successively, each of which is rotating with a greater peripheral speed than the previous one, and then into a centrifugal box or other collecting device. One or more of the godets is partly immersed in a hot liquid; those godets so immersed are substantially cylindrical for only a portion of their length and conical or tapered for the remainder, and they are so arranged that at least a part of the conical or tapered portion projects from the surface of the hot liquid. Thus in the Figure, viscous material is extruded from a nozzle 2 into a coagulating bath 3, and the bundle of filaments 4 so formed is led over the guide 5 to the cylindrical part 13 of the rotating godet 7 round which it is passed twice, the guide 8 being used for this purpose; from the godet 7, which is partly immersed in hot water, &c., the filaments are passed twice round the second godet 10 with its accompanying guide 9, which is rotating at a greater peripheral speed than the godet 7, to a collecting box 11. At starting, the operator then passes the filaments round the conical portion 4 of the godet 7, such portion being clear of the hot liquid.
