Abstract

The material web (15) is guided through a treatment zone which is formed by numerous collector tubes (33, 34, 35) and by a shaft. Each collector tube is provided with a separate connection (36, 37, 38) and can be fed with its own treatment medium. The collector tubes preferably form a unit which is adjustable through a limited range in relation to the fabric web (15). Through the combined use of liquid and gaseous treatment mediums (44, 45, 46) an intense effect can be achieved, for example for washing, impregnating or similar.
