Press section and press section/frame construction combination in a paper machine

A press section-frame construction combination in a paper machine, said paper machine including a forming section having a forming wire, comprising:

• a first upper fabric;
• a pick-up press-suction roll within a loop of said first upper fabric situated proximate to a run of the forming wire for transferring a web from the forming wire onto said first upper fabric;
• a first lower fabric;
• a first lower press roll within a loop of said first lower fabric situated in nip-defining relationship with said pick-up suction roll to form a first double-felted press nip;
• a smooth-surfaced center roll;
• a second press roll situated within the loop of said first upper fabric situated in nip-defining relationship with said center roll to form a second single-felted nip directly, consecutively following said first double-felted nip and through which only said first upper fabric passes;
• said upper fabric having a substantially straight upwardly inclined run between said first double-felted nip and said second single-felted nip;
• a frame construction on which said pick-up press-suction roll, said first and second press rolls, and said center roll are mounted, and wherein
• the web is transferred by said pick-up press-suction roll from the forming wire onto said first upper fabric and is carried on lower surface of said first upper fabric into said first double-felted nip wherein the web is dewatered through both of its faces, whereupon the web is carried supported on said first upper fabric over said substantially straight run into said second, single-felted nip whereupon the web separates from said first upper fabric and is carried on the surface of said smooth-surfaced center roll,
• a third press roll mounted on said frame construction and situated in nip-defining relationship with said center roll to form a third single-felted nip;
• a second upper fabric passing through said third single-felted nip, wherein
• after separation from said first upper fabric, the web is carried on the surface of said smooth-surfaced center roll into said third single-felted nip, and
• wherein said second nip is located at a point above a horizontal plane passing through an axis of rotation of said center roll and on a side of a vertical plane passing through an axis of rotation of said center roll closer to said first nip, and wherein said third nip is located on the opposite side of said vertical plane.
