摘要
An apparatus and process for depositing slurry upon a moving forming web. The apparatus includes a pivotally mounted headbox for depositing slurry from the inner bottom surface of the headbox down an inclined spillway as a continuous curtain onto a moving web. The headbox is mounted transverse to the direction of travel of the moving web. The headbox also has vertical edge boards, including a headbox back edge board and two opposed headbox side edgeboards, on three respective sides of the headbox to prevent slurry from spilling over the sides and back of the headbox. The headbox is supplied with slurry from a slurry mixer by a feed line mounted on a reciprocating trolley which moves, transverse to the direction of travel of the moving web, back and forth along the length of the headbox.
