Paper machine twin-wire former |
(57) A paper machine twin-wire former of the type that paper stock jetted from a head-box
(5) is immediately pinched between the first (3) and the second (4) dewatering wires
respectively forming loops, and formation of a wet paper sheet is performed between
these dewatering wires, is improved. The improvements reside in that a stationary
shoe (40) is disposed within the loop of the first wire (3) as supporting the first
wire for performing dewatering to the side of the second wire (4) and suppresses a
dewatering effect to the side of the first wire. A dewatering instrument (10) is disposed
within the loop of the second wire (4) as opposed to the loop of the first wire (3)
and as supporting the second wire, and performs a suction dewatering effect to the
side of the second wire.
