Abstract (en)
[origin: WO0012819A1] A process for making paper on a paper-making machine comprising providing a cellulosic thin stock-suspension, flocculating the suspension by adding an aqueous solution of a polymeric retension aid selected from natural and synthetic polymer and thereby forming a flocculated suspension, shearing the flocculated suspension, reflocculating the sheared suspension by adding an aqueous reflocculating suspension, draining the reflocculated suspension through a wire to form a sheet, and drying the sheet, characterised in that substantially fully cooked starch is added to the suspension after the shearing and before the draining.
