    摘要: Twin-wire former for producing a fibrous web. The former includes two endless wire belts arranged to form a twin-wire zone, a dewatering element, and a headbox positioned at an angle relative to an imaginary first horizontal plane. The twin-wire zone includes a first section in which the two wire belts are arranged to run over the dewatering element. The two wire belts are further positioned to form a wedge-like inlet gap that is structured and arranged to receive a fibrous stock suspension directly from the headbox. Additional dewatering elements are utilized. The twin-wire zone includes a second section in which the two wire belts along with the fibrous web formed between the two wire belts are arranged to run downward over the additional dewatering elements. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
