摘要： The invention relates to a method and a device for drying a pulp web, with dewatering of the pulp web by pressing and the pulp web being guided directly on the press belt to a first transfer area for transfer of the pulp web to a transfer clothing and transfer of the pulp web in a second transfer area to a dryer. It is characterized in that the pulp web undergoes thermal drying between the first transfer area and the second transfer area. This enables production of a pulp web with improved quality characteristics and low energy consumption at the same time.

摘要： A device and a method for producing a pulp web in which the first clothing and the second clothing are wrapped partly round the forming roll and another roll. The pulp web formed is guided between the forming roll and the other roll on the first clothing and the second clothing is guided separately from the first clothing, at least in one section. This enables the pulp web to be produced with low energy consumption and operating costs.
