Japanese Patent JPH0726354

B2

A forming apparatus (10) is disclosed for forming a web (W) from stock (S) ejected through a slice lip (12) of a headbox (14). The apparatus (10) includes a first wire (16) which extends in an endless loop (18) past the slice lip (12) such that the stock (S) is ejected through the slice lip (12) onto the first wire (16). A second wire (20) extends in a further endless loop (22) with the second wire (20) cooperating with the first wire (16) for defining therebetween a forming section (24) having a first and a second end (26, 28) such that the web (W) is formed during passage of the stock (S) through the forming section (24). A first and a second turning bar (30, 32) are disposed respectively within the endless loop (18) and the further endless loop (22) adjacent to the first end (26) of the forming section (24) such that the slice lip (12) is disposed in close proximity to the first end (26) of the forming section (24). The apparatus (10) also includes a curved drainage device (34), a first slot (36), a box (38), a second slot (42) and a further curved drainage device (44). The curvature of the curved drainage device (34) and the box (38) is opposite to the curvature of the further curved drainage device (44) such that the stock (S) is progressively drained through both wires (16, 20) during passage through the forming section (24) from the first (26) towards the second end (28) thereof.
