Abstract
This invention involves the use of a positive pulse blade to precondition a wet web of material carried on a wire mesh. The blade (22) is removably mounted in fixed position relative to a wet web of material (28) and mesh to be passed thereover. An upper wear surface (52) is on the blade for engagement with the mesh. Force is applied to entrain water from the web on the underside of the mesh. The blade has a leading edge (48) with a configuration tending to direct all of the water entrained on the underside of the mesh when it is moved toward the blade up through the web to apply a positive pulse to the wet web and precondition the web for facilitating later dewatering of the web. <IMAGE>
