ABSTRACT:
The invention relates to a method and apparatus for continuous wet-in-wet processing of a length of material in which a continuously regulated additional dosaging occurs using a treatment both of low content, the quantity of treatment liquor added being always exactly the quantity which has just been carried off by the outgoing length of material. In this way the bath concentration can be kept constant with a high degree of accuracy and the balance in the bath is also achieved quickly.
