Claim:
A pulp processing apparatus comprising a first endless wire, a second endless wire opposed to said first endless wire, said first and second endless wires being conveyed in the same conveying direction to define a web-forming space therebetween for dewatering a web pulp, first and second perforated dewatering tables supporting said first and second endless wires, respectively, for pressing said first and second endless wires towards said web, said first and second perforated dewatering tables including a front end and a back end with respect to said conveying direction of said first and second endless wires, said back end of said first perforated dewatering table being upstream of said back end of said second perforated dewatering table, and a press roll downstream of said back end of said first perforated dewatering table, said press roll being opposed to said back end of said second perforated dewatering table so as to form a nip between said press roll and said back end of said second perforated dewatering table, said back end of said second perforated dewatering table including a profiled surface that interacts with said press roll so as to prolong said nip between said press roll and said back end of said second perforated dewatering table wherein said profiled surface is located upstream of said press roll with respect to said conveying direction of said first and second endless wires includes a slope away from said opposed press roll and having substantially at least the same curvature as the surface of said press roll.
