Title (EN) HEADBOX AND STOCK DELIVERY SYSTEM FOR A PAPERMAKING MACHINE
(FR) CAISSE DE TETE ET SYSTEME D'ALIMENTATION EN PATE DE MACHINE A PAPIER
Abstract: front page image
(EN)A headbox including a stock dilution profiling arrangement and associated stock delivery systems are provided, which together deliver to the forming section of a papermaking machine a uniform stock flow with more consistent basis weight and fiber orientation profiles than has previously been possible. These improvements in basis weight uniformity and fiber orientation profile provide benefits in paper sheet formation and related paper properties.
(FR)La présente invention concerne une caisse de tête comprenant un dispositif de profilage de dilution de pâte et des systèmes d'alimentation en pâte associés, qui agissent de concert pour alimenter l'unité de formage d'une machine à papier en un flux de pâte uniforme avec des profils de force du papier et d'orientation des fibres plus homogènes que ceux possibles auparavant. Ces améliorations en termes d'uniformité de force du papier et de profil d'orientation des fibres se traduisent par une meilleure formation d'une feuille de papier et de meilleures propriétés de papier connexes.
