Abstract

Filled paper is made by providing an aqueous feed suspension containing filler and cellulosic fibre, coagulating the fibre and filler in the suspension by adding cationic coagulating agent, making an aqueous thinstock suspension by diluting a thickstock consisting of or formed from the coagulated feed suspension, adding anionic particulate material to the thinstock or to the thickstock from which the thinstock is formed, subsequently adding polymeric retention aid to the thinstock and draining the thinstock for form a sheet and drying the sheet.
