Beschreibung
Zusammenfassung:	The present invention relates to processes and apparatuses for producing hydrophobized fiber cement sheets as well as fiber cement sheets obtainable therewith. In particular, the present invention provides processes for manufacturing a hydrophobized fiber cement product, said process at least comprising the steps of: (i)forming at least one fiber cement film on a rotating sieve (17) in contact with a fiber cement slurry in a vat (16); (ii)transferring said at least one fiber cement film from said sieve (17) to a felt transport belt (3), (iii)applying a hydrophobizing agent to said at least one fiber cement film, and (iv)accumulating the fiber cement film on an accumulator roll (1) via the felt transport belt (3), so as to form a hydrophobized fiber cement product. The present invention further relates to various uses of the fiber cement sheets obtainable by the processes of the invention in the building industry.
