This document summarizes a patent for improvements in the manufacture of viscose. Specifically, it describes an apparatus that uses a rotating perforated plate and roller to break up lumps of cellulose xanthate in a slurry with caustic soda solution. The lumps are deposited on the plate and squeezed through the perforations by the roller to more finely divide the cellulose xanthate. This facilitates faster dissolution and yields viscose free of lumps. Diagrams of the apparatus are provided showing its components and operation.
