A forming apparatus (10) for forming a web from stock. The apparatus (10) includes a frame (14) and a first and second plurality of guide rolls (16-26 and 30-34) rotatably connected to the frame (14). A first and second forming wire (28, 36) extend respectively around the first and second plurality of guide rolls. With the first and second wires (28, 36) cooperating together to define therebetween, a forming section (38) having a first and second (40, 42) end. A headbox (12) is disposed adjacent to the first end (40) of the forming section (38). A suction shoe (44) is disposed adjacent to the first end (40) of the forming section for effecting an initial dewatering of the web. The suction shoe (44) has a curved surface (46) which abuts against the first wire (28) for removing a first portion of the water through the first wire (28) and a second portion of the water through the second wire (36). A vacuum slot (52) collects the second portion of water and a roll (17) is disposed between the vacuum slot (52) and the second end (42) of the forming section (38) for removing a third portion of the water from the formed web thereby resulting in a gradual increase in dewatering from the first to the second end of the forming section (38) thereby minimizing removal of fines from the stock and inhibiting two-sidedness of the resultant web. |
