Dewatering arrangement on the press section of a web-forming machine

A dewatering apparatus in a press section of a web-forming machine, the web-forming machine having a cross machine direction width, the dewatering apparatus comprising:

• a press suction roll mounted for rotation in a first direction and having a circumferential surface, the press suction roll being engaged with a second roll of the press section to form a press nip;
• and
• a press fabric forming an endless loop to contain the press suction roll and to wrap about a portion of the press suction roll, and to travel in the first direction, wherein the press fabric forms a closing gap defined between the press suction roll and the press fabric as the press fabric comes into engagement with the press suction roll, and wherein the press fabric forms an opening gap defined between the press suction roll and the press fabric where the press fabric leaves engagement with the press suction roll;
• a saveall installed within the press fabric endless loop in an area between the opening gap and the closing gap extending essentially over the entire width of the web-forming machine;
• a concave guide surface forming part of the saveall which extends from the opening gap closely spaced from the circumference of the press suction roll and is arranged to produce a vacuum effect to remove water from the press suction roll;
• and
• wherein the saveall has a first part hingedly connected to a second part by a joint, the first part being closer to the opening gap than the second part, and wherein the concave guide surface is part of the first part.
