摘要： A process for the production of a multilayer fiber web from cellulose fibers by separately feeding at least two different fiber suspensions and water into a multilayer headbox, in which they are separated by separating elements from one another and from water and, after leaving the nozzle mouth of the headbox, reach an apparatus on which a web is formed, the water being transported in such a way that, after emerging from the nozzle mouth, it reaches the web-forming apparatus in the form of a layer between two layers of fiber suspensions and thus counteracts mixing of the different fiber suspensions, wherein, for improving the retention, drainage and formation, at least one retention aid and/or at least one drainage aid are metered into the fiber suspensions and/or into the water fed in.
