Title: Apparatus for treating a tow of filaments with a liquid

Abstract: An apparatus for treating a tow of filaments with a fluid, the apparatus forming a tow path therethrough and having a pair of guide surfaces positioned on opposite sides of the tow in series with each other in such a manner that the two path has at least two bends. Fluid nozzles associated with each of the guide surfaces are positioned in such a manner that fluid from these nozzles flows in layers along the guide surfaces and passes through the tow at the bends in the two path. This apparatus is capable of treating a tow under little or no tension, so that it can be used to anneal and shrink tows of certain filaments. The moving fluid advances the tow through the apparatus.
