ABSTRACT:
An apparatus for the production of a fibrous web, especially a tissue or hygienic web, the fibrous web runs through a press nip which is formed by a press unit and a backing roll and the web is subsequently run through a creping nip which is formed by the backing roll and a creping roll around which a textured belt is looped. Moreover, the creping roll is equipped with its own drive. The creping roll can be pressed against the backing roll through a pivoted lever whose pivoting axis which is parallel with the axes of the creping roll and is positioned such that the connecting line between the pivoting axis and the creping roll axis forms an angle of approximately 90° with the connecting line between the creping roll axis and the backing roll axis, when viewed in a vertical plane relative to these axes.
