Abstract
A papermaking process of the type in which prepared thick pulp stock is supplied to a head box from which it flows down to a mixing point where it is diluted with paper machine backwater, the resultant thin stock being pumped to a breast box on the paper machine, characterised in that, for manufacturing paper containing acid-reactive filler and sized by employing rosin and papermakers' alum, the filler is added to paper pulp which has already been treated with rosin size and sufficient alum for fixing the size, and further alum is subsequently incorporated in the diluted pulp before application of the pulp to the papermaking machine.
