摘要： The invention relates to a method for producing paper with a high substance weight. According to said method, a paper material is dewatered on a screen in the presence of a combination of at least two polymers that act as a retention and dewatering agent system, forming sheets, which are then dried. The sheet formation takes place without the use of fine-particled inorganic flocculants and (a) at least one polymer containing amino groups and (b) at least one branched cationic polyacrylamide are used as the retention and dewatering agent.
