ABSTRACT OF THE DISCLOSURE Finely divided fiber material is treated in a continuously fed verti- cal treatment vessel. The fiber material is passed through the vessel in the form of a column of material , which is interrupted between successive treat- ment stages, for example, between impregnaiton and cooking or between cooking and washing. The interruption(s) break up the fiber material column and at this point the fiber material moves through a liquid layer and thereafter re- forms the column with a degree of compaction which is not influenced by the weight of the fiber material above the liquid layer.
