MACHINE AND PROCESS FOR THE PRODUCTION OF STRUCTURED PAPER

Paper making machine comprising a forming zone in which a layer of fibrous material is formed, a zone for forced removal of water from the fibrous web downstream of the forming zone, and a drying zone downstream of the forced water removal, wherein a structured wire (4) configured to support and transport the layer of fibrous material through the forced water removal zone is arranged, and the structured wire (4) has an inlet section of entrance in the forced water removal area and an exit section from the same zone. In the forced water removal zone there is a pressing zone (ZP) for the layer of fibrous material supported by the structured wire (4) in proximity of said entrance section, in the pressing zone (ZP) being arranged and acting pressing means configured to compress the layer of fibrous material supported by the structured wire (4). Downstream of the pressing zone (ZP), with respect to a direction (MD) followed by the fibrous web inside the machine, there are additional devices for forced removal of the water from the fibrous web.
