Abstract: Process for the transformation of comminuted cellulose ether, which has been rendered at least largely water-insoluble by modification but is still highly swellable with water, into an easily workable material, comprising wetting a hydrophilic support web, applying the comminuted modified cellulose ether to the wetted web, and drying. This invention also relates to an apparatus for performing the process.
