Abstract
Abstract One or more liquids may be applied to a running textile web in flat tubular or open width form by three different cooperative and integrated systems. A drying chamber is associated with the apparatus for recovering solvent which may be included in certain liquid chemicals. The chemical applicating apparatus includes spray nozzles spaced transversely adjacent the path of travel of the web for spraying chemicals on the moving web. Guiding means are provided for selectively positioning the web with respect to the nozzles for optimum spraying position. A padding tank is also provided for passing the web directly through a bath of the chemical and a metering system including an applicator roll and an adjustable blade in different configurations is provided for applying precisely controlled amounts of chemicals to the web.

Total Claims: 11
Claim 1
Independent Claim
171 words
Apparatus for treating a running web, comprising a. a housing, b. a spray station in said housing adapted to spray liquid therefrom, c. first guide means for guiding said web through said spray station to receive a spray of liquid, d. a padding station in said housing including a tank adapted to contain a quantity of liquid, e. second guide means for guiding said web into and out of said tank, f. a metering station in said housing including an applicator roll, a blade adjustably mounted in cooperative spaced parallel relation to said roll and feed means for delivering a flow of liquid between said roll and said blade whereby a film of liquid will be formed on said roll, g. third guide means for guiding said web into and out of contact with said roll, h. a drying and condensing stage in said housing for drying said web and condensing vaporized liquid from said web, and, i. fourth guide means for guiding said web through said drying and condensing stage.
