CA 2399322

A paper former comprises two wires which converge for defining a paper production gap and dewatering blades arranged in the paper production gap area in a paper producing direction and brought into sliding contact with one of the two wires so that a stock is dehydrated while being conveyed in a state put in the paper production gap. Each of the dewatering blades is shaped into a convexly curved surface configuration bent along a traveling direction of the wires and equipped with a wire sliding contact surface brought into sliding contact with the wire for guiding the traveling of the wire. Grooves are made in the wire sliding contact surfaces as a moisture run-off opening for running off moisture developing through the dewatering from the wire side.
