Abstract
A wire section in a machine for the production of a fiber web including at least one twin wire former including a revolving continuous inner wire and a revolving continuous outer wire that converge in the area of a forming roll. After the forming roll, viewed in the direction of web travel, and inside the loop of the inner wire and inside the loop of the outer wire at least one additional strip element is located.
Claims13
A wire section in a machine for the production of a fiber web, comprising:
- at least one twin wire former, including:
- a revolving continuous inner wire and a revolving continuous outer wire that each include a loop and converge in the area of a first forming element;
- a first strip element located opposite said first forming element and proximate to at least one of said inside inner wire and said outer wire;
- and
- at least one additional strip element located after said first forming element, viewed in direction of web travel, inside another of the loop of said outer wire and the loop of said inner wire, at least one said additional strip element including at least one suction element, said at least one suction element being an integral unit that is structured and arranged for providing a vacuum that increases in the direction of wire travel, at least one said suction element being a suction box, said suction box having an essentially flat surface.
