fig1 the forming belt 16 travels around a path defined by a series of guide rollers the forming belt 16 travels from an upper guide roller 20 positioned below and proximate to the headbox nozzle 14 horizontally and away from the headbox nozzle to another upper guide roller 22 passes through the upper guide roller 22 and diagonally and downwardly to a lower guide roller 24 passes under the lower guide roller 24 and diagonally and upwardly toward the nozzle 14 to a lower guide roller 26 passes over lower guide roller 26 and diagonally and downwardly to lower guide roller 28 passes under lower guide roller 28 and turns upwardly and slightly inwardly to a guide roller 32 passes behind the guide roller 32 and upwardly and outwardly returns to upper guide roller 20 a vacuum forming box 34 positioned beneath the forming belt 16 proximate to the opening 36 of the headbox nozzle 14 immediately extracts water from the moist fibrous web 38 deposited on top of the forming belt by the headbox nozzle the partially dewatered fibrous web is carried by the forming belt 16 in the clockwise direction as shown in fig1 towards the upper guide roller 22 the fibrous web 38 as it moves away from the vacuum forming box 34 in one embodiment may comprise from about 19 percent to about 30 percent cellulosic fiber by weight an edge.
