<p>The invention relates to a device (3) for drainage of a pulp web (10), particularly a tissue web, having a first pressing zone (15.1) having a pressing zone length of L1 through which the pulp web (10) is fed horizontally between a circulating, permeable band (8) and a circulating, permeable support band (9), wherein the first pressing zone (15.1) is designed such that a fluid can flow through the band (8), the pulp web (10) and the support band (9) at least on one part of the pressing zone length L1. In addition, the device has a subsequent second pressing zone (15.2) having a pressing zone length of L2. The invention is characterized in that the pulp web (10) is guided through the second pressing zone (15.2) between two bands (8, 9) having differing compressibility.</p> |
