ABSTRACT:
The invention relates to an arrangement for a drying section of a paper machine, the arrangement comprising a fine wire (5a) and a coarse wire (5b) that are arranged to pass between metal bands (2, 3) of a band dryer (1) together with a web (4) to be dried. The fine wire (5a) comprises at least three interwoven textural layers, wherein the outermost layers, in other words a surface (10) and a bottom (11), have a finer texture than the middle section (12) situated between them. According to a preferred embodiment, the surface layer (10) is provided with a denser texture than the bottom (11), which, in turn, has a denser texture than the middle section (12).
