A method and apparatus for forming a paper web from a fiber suspension are disclosed. These include injecting a fiber suspension stream through a slice opening onto the upper surface of a travelling paper web-forming surface, maintaining that surface free of support for a predetermined distance downstream of the slice opening, maintaining a flexible lip near the upper surface of the web-forming surface for a portion of that predetermined distance, and applying a vacuum to the lower surface of the web-forming surface throughout the predetermined distance. In this manner, both the method and apparatus can produce a paper web and substantially dewater the fiber suspension within the space between the flexible lip and the web-forming suspension and substantially reduce disturbances during formation of the web and throughout the predetermined distance.
