Abstract

The present invention relates to a method for manufacturing paper board which contains no inorganic filler. Pulp fines from the white water system and retention agents are mixed and then fed to the stock upstream of the paper machine prior to blending with the long fiber stock. Once flocculation takes place, the stick is drained to form a sheet and the sheet is dried.
