water is drained from the stock and a very thin wet sheet is carried over to various other dewatering devices such as foil blades in hydrofoil section 20 until a sheet paper dryness of around 1 to 1 5 is achieved following this the paper dryness is increased by the foil blades in the varioline and vaculine in the low vacuum section 20 to a dryness level of 5 next a paper dryness of 8 to 10 is achieved in the elements of the low vacuum section 30 and the sheet is transferred to the high vacuum section 40 to achieve a paper dryness of 18 or greater finally the sheet is transferred over the couch roll where additional dryness level is achieved a fourdrinier composed of the previously described equipment is fitted with a plurality of adjustable angle and height foil blades starting from the forming board section 10 and partially through the low vacuum section 30 as the stock travels with the forming fabric 105 it encounters the adjustable angle and height foil blades at various points along the dewatering table to manipulate the paper web and orient more fibers in a desired direction on the forming board section 10 and the hydrofoil or gravity section 20 the adjustable angle foil blades generate a vacuum pulse that dewaters the.
