The latest headboxes for board and packaging grades

Abstract

The one of the most important parameter for product quality in board and packaging (B & P) grade is still its strength basically. But new trend in B & P grade is reduction of basis weight, and requirement in product is not only its strength but also the fineness of the surface quality, which influence printability. Due to these tendencies, better quality and higher performance must be required for the headboxes for B & P grade compared with those in the past. VOITH Paper had developed Masterjet headboxes. based on the well-known technology of the high-turbulence W-type headbox and Modulejet dilution control, to meet the higher demands from the paper industry. On the other hand, VOITH Paper also considers economical solutions for the B & P grades.
