The headbox is a key tool for quality and economy improvement in paper production. Main areas of development in recent years have been the multi-layer headbox as well as independent control of the CD profiles of basis weight and main fiber orientation (MFO).
Up to now, the CD basis weight profile had been controlled by local adjustment of the slice gap. This can, however, lead to an uneven CD profile of main fiber orientation. A new type of CD basis weight control is gaining popularity based on local dilution of the suspension in the headbox. With the dilution principle, there are two different solutions for influencing the CD profile of MFO independently from that of basis weight.
