Paper making machine and process

A process for production of paper comprising a formation step in which a layer of fibrous material is formed, a step of forced removal of water from the layer of fibrous material downstream of the formation step, a drying step downstream of the forced water removal step, and a paper collection step downstream of the drying step, wherein the transport of the layer of fibrous material along a path that follows a predetermined transport direction (MD) is executed by means for transporting the layer of fibrous material, along said path said operating steps are executed in succession, characterized in that the forced removal of the water step includes, in turn, two consecutive steps in which the layer of fibrous material passes over a capillary roller (44) and a pressure element (4S) with a respective counter-roller (4C) acting consecutively on the layer of fibrous material upstream of the drying step, the two consecutive steps being performed in two consecutive zones (Z1, Z2) along said transport direction (MD), in which are respectively arranged the capillary roller (44) and the pressure element (4S) with the respective counter-roller (4C) such that the capillary roller (44) and the pressure element (4S) with the respective counter-roller (4C) act consecutively on the layer of fibrous material.
