Abstract:
A multiply former apparatus is disclosed for forming a base, top and intermediate ply. The apparatus includes a fourdrinier wire for receiving thereon the base ply. A first twin wire former is provided for forming the intermediate ply, the first former cooperating with the fourdrinier wire. A second twin wire former forms the top ply, the second former cooperating with the fourdrinier wire. The second former includes a third looped wire which cooperates with a fourth looped wire for defining therebetween a second forming section for forming the top ply. A vacuum box is disposed upstream relative to a further vacuum device such that the fourth wire is disposed between the vacuum box and the third wire. The vacuum box assists in removing water from the second forming section for increasing a capacity of the apparatus.
