Method & Apparatus For Web Treatment Abstract of the Disclosure A running textile web that has been subjected to soaking by a liquid such as a scouring solvent is carried between a suction box located adjacent one face of the web and a source of pressurized and relatively dry heated gas adjacent the other face thereof and opposite the suction box. The heated gas passes through the web and is drawn into the suction box, en- hancing the amount of liquid removed at this stage and present- ing the web into a drying stage with less entrained liquid than if the web were subject to the action of the suction box only. The amount of mechanical mist is kept to a minimum within a closed scouring range by means of a closed loop between the suction box and a return conduit provided with a trap contain- ing a batt of metallic wool. The liquid discharge from nozzles employed to uncurl the edges of the web is directed against shields also containing a batt of metallic wool to reduce bounc- ing, noise and mist generation.
