ABSTRACT OF THE DISCLOSURE A twin-wire former for a paper machine which can produce paper of good formation over a wide range of basis weight and at a speed of wide variation essentially consist- ing of a top wire and a bottom wire. The bottom wire with a wet material thereon substantially horizontally travels. The top wire approaches the material from above and travels downward together with the bottom wire on the circumference of a supporting member provided in the loop of the bottom wire while pressing the material between the pair of wires. At the position of a force roll provided in the loop of the top wire, the pair of wires commence travelling upwardly through a suction box to a couch roll, where the pair of wires separate from each other. To adjust the wire contact- ing angle of the supporting member, and hence, to improve the formation of paper, each of a water receiver, the force roll and suction boxes are made movable.
