Abstract

A process for making paper of the type in which pulp pulp is supplied to a collection box from where it flows to a mixing point where it is diluted with return water from the paper machine, the resulting pulp being pumped to a head tub of machine, characterized said process by the fact that to make paper containing a reagent reactive to acids and prepared by using rosin and paper industry alum, the filler is added to the paper pulp already treated with rosin sizing and enough alum to fix the sizing, incorporating then the alum to the diluted pulp before proceeding to the application of the pulp to the paper machine.
