Abstract

The invention relates to a process for the production of paper on a paper machine containing a dilution headbox in which a main aqueous flow containing cellulosic fibres and filler is mixed in said headbox with a diluting aqueous flow to form a resulting aqueous flow which is ejected onto a wire and dewatered to form a web of paper, wherein one or more components providing improved retention are introduced into the main aqueous flow and an additive resulting in slower dewatering and/or being selected from non-ionic and anionic organic polymers is introduced into the diluting aqueous flow.
