ABSTRACT:
Means for applying foamed treating liquor to a flat width traveling textile substrate using a cylindrical supporting member extending axially transversely across the width of the substrate and supporting a projecting applicator nozzle. A circumferentially extending distribution chamber is formed on the cylindrical supporting member by a cover plate mounted in spaced relation on the cylindrical supporting member by resilient side strips to which the cover plate is tightened circumferentially in sealing disposition. The distribution chamber diverges from an inlet port adjacent the nozzle circumferentially around a major extent of the cylindrical supporting member to the full width of the nozzle. End closures are slidably manipulated in the ends of the nozzle to limit the transverse extent of the nozzle opening in following relation to variations in the transverse positions of the edges of the traveling substrate in response to a sensing device. A plate-like projection may be provided across the distribution chamber adjacent the nozzle to restrict flow of the foamed treating liquor and thereby assure proper uniform distribution of the liquor across the distribution chamber to the nozzle. The projection preferably tapers from a maximum circumferential extent at the center to minimum extents at the outer ends for further assurance of proper transverse distribution of the foamed treating liquor across the distribution chamber to the nozzle.
