Abstract (en)
[origin: WO2008069728A1] The invention relates to a drying box for drying a cellulose pulp web. The box has a plurality of fans (3, 5), each fan being driven by a motor (9, 11) and contributing to generate a positive pressure in the drying box interior (7). The shaft between a motor (9) and a fan (3) is provided with a reverse blocking arrangement (19) which prevents the fan from being driven in the reverse direction by the positive pressure in the drying box, in case its motor is not operating.
