摘要：A method includes receiving a measurement associated with an anisotropy of a first surface and a measurement associated with an anisotropy of a second surface of a sheet of material. The method also includes adjusting an operating parameter associated with a headbox based on the measurements. The headbox is associated with manufacture of the sheet. The operating parameter could include a jet speed, a jet impingement angle, a jet thickness, a slice opening, and/or a slice apron projection. Adjusting the operating parameter could be based on a difference between a measured anisotropy of the first surface and a measured anisotropy of the second surface. For example, the operating parameter could be adjusted to achieve a desired difference between the measured anisotropy of the first surface and the measured anisotropy of the second surface. Multiple headboxes could be controlled, such as when different headboxes are used to produce different layers of a multi-layer sheet.
