Abstract

Paper machine for manufacturing a fiber web of paper without through air drying (TAD) or pressing, comprising: a wet end, having a wire section with at least one forming wire, a clothing, being air and water permeable, and a dewatering unit for dewatering the fiber web; and a drying section, comprising a drying surface for the fiber web; and also a transfer roll for transferring the fiber web to the drying section, wherein the fiber web is supported by said clothing from the wire section all the way to and over the transfer roll. The clothing has a three dimensional structure for structuring the fiber web.
