Abstract

A cylinder-type papermaking machine for forming a paper web such as grades of board including a pressure headbox on the uprunning side of the porous cylinder having a plurality of flexible upstream anchored trailing self-positionable members in the headbox with the headbox having a lower slice wall, an upper slice wall, and a forming zone roof member extending from the upper slice wall along the uprunning side of the cylinder. The forming zone roof member is flexible and tapers in thickness in the downstream direction. Hinges and jacks operate to adjust the positioning of the upper slice wall as well as the curvature of the forming zone roof member.
