Abstract
Abstract Apparatus for washing, drying and fixing a textile web having endless, driven means for moving a textile web successively through washing, drying and fixing zones and wherein the web is partially dried prior to the drying zone by causing an airstream to pass through the web. Partial drying of the web is facilitated by vibrating the web and means is provided for recovering the washing solvent. Means is provided for condensing or preventing condensation of vaporized washing solvent depending upon whether the washing liquid is cold or hot, respectively.
