Abstract
Apparatus particularly adapted for applying foamed treating liquor to a flat width of a traveling non-woven textile substrate includes a longitudinal tubular foam distribution nozzle one side of which has a plurality of closely-spaced staggered apertures for engaging and applying pressurized foam widthwise across the substrate and a driven drum opposed to the nozzle engaging widthwise the opposite side of the substrate for imparting traveling movement to the substrate. The drum and nozzle cooperate to compress the substrate therebetween in covering relation over the apertures to prevent lateral escape of the foam therefrom and to confine the emission of foam therethrough, thereby to uniformly control foam application across the substrate width as it travels by the nozzle. Limited contact of the apparatus with the substrate prevents frictional pulling and structural damage thereto. The drum is perforated for escape of the air component of the foam and to enhance foam penetration of the substrate. If desired, one apparatus may be employed to achieve full substrate penetration or two serial apparatus may be arranged to treat respectively opposite substrate sides for full penetration.
