Zusammenfassung:	To provide a method for processing a paper excellent in application efficiency and capable of sufficiently exhibiting the effect of a chemical for a papermaking stage.SOLUTION: A method for processing a paper X1 applies a chemical for a papermaking stage to a wet paper X in a papermaking stage, and has: a first step in which a chemical for a papermaking stage is applied to the wet paper X running through a press part P2 after being pressed by press rolls Pr or through a dry part P3 and having a moisture percentage of 10 to 60%; and a second step in which the wet paper X applied with the chemical for a papermaking stage is dried in the dry part P3 so as to be a paper.SELECTED DRAWING: Figure 1 【課題】付与効率に優れ、抄紙工程用薬品の効果を十分に発揮することができる紙の加工方法を提供すること。【解決手段】本発明は、抄紙工程における湿紙Ｘに抄紙工程用薬品を付与する紙の加工方法であって、プレスロールＰｒでプレスされた後のプレスパートＰ２、又は、ドライパートＰ３、を走行する湿紙Ｘであり、且つ、水分率を１０～６０％とした湿紙Ｘに対し、抄紙工程用薬品を付与する第１ステップと、該抄紙工程用薬品が付与された湿紙ＸをドライパートＰ３で乾燥させ紙とする第２ステップと、を有する紙Ｘ１の加工方法である。【選択図】図１
