Abstract

The method of manufacturing a flattened curled paper with smooth surfaces on which it can be printed, and endowed with a high degree of deformability without entrusting it to the unfolding of curled folds or folds, a method comprising the steps of: forming a fibrilous tangle wet afeltration of approximately 15% to 25% absolute dryness; passing the tangle through a first squeeze against a curling roller; detach the tangle of the curling roller with a regulating sheet, forming a curled tangle of approximately 25% to 30% absolute dryness; to pass the curled tangle, still approximately 25% or 30% dry only, through a second pressure zone to remove more water from it and reorient the fibers, while smoothing the faces of the tangle producing a flattened tangle of approximately 30% to 40% absolute dryness; heat the tangle from the second press and simultaneously remove more moisture from it forming a tangle of approximately 50% to 60% absolute dryness; to subject the heated tangle to a high pressure to stick its fibers together and to smooth the surfaces of it even more; and continue drying the resulting web until dry commercial paper.
