A method of preventing an over-adhesion of paper on the surface of a press roll of a paper machine for long period and also preventing wear and contamination, the press roll being in a state of being supplied with paper by the operation of the paper machine, the method comprising the step of continuously supplying a wax having a melting point lower than the surface temperature of the press roll at 0.01 to 10 mg/m2 on a passing paper basis directly onto the surface of the rotating press roll.

La présente invention concerne un procédé visant à empêcher une adhérence excessive de papier à la surface d'un rouleau de presse d'une machine à papier pour une longue durée et aussi d'empêcher l'usure et la contamination, le rouleau de pression étant dans un état d'être alimenté en papier par le fonctionnement de la machine à papier, le procédé comportant une étape d'alimentation en continu d'une cire présentant une point de fusion inférieur à la température de surface du rouleau de pression entre 0.01 et 10 mg/m?2¿ sur la base d'un papier passant directement sur la surface d'un rouleau de pression en rotation.
