ABSTRACT:
A method an apparatus for manufacturing a fiber web, in particular a web of tissue or hygiene material, provided with a three-dimensional surface structure, whereby the fiber web is pressed at a dry content of <25% onto an imprinting fabric by way of a first pressure field and is thereby pre-imprinted and is subsequently once more pressed onto an imprinting fabric by way of a further pressure field for further dewatering and drying in order to fix the three-dimensional surface structure and strength. Moreover, the dry content is achieved by a favorably priced apparatus instead of by a TAD drying apparatus.
