ABSTRACT:
Apparatus for continuous wet treatment of elongated materials, such as travelling textile webs and the like, namely for soaking the webs with liquids, applying chemicals thereto, dyeing, washing and rinsing them. The web is passed through a closed space, preferably in an upward direction, between two rows of vertically spaced-apart rollers. The travelling web is subjected to a short-duration action of a hot liquid in at least two separate, consecutive stages which can be in the form of dish-shaped containers that hold the liquid underneath some of in a hot gaseous medium for a longer time than the liquid exposure; and the liquid adhering to the travelling web is squeezed out between at least two consecutive liquid stages, and preferably returned to a container of a stage through which the web was previously guided.
