摘要: A method includes receiving a measurement associated with an anisotropy of first surface and second sheet material (108, 215). The also adjusting operating parameter headbox (112, 240-250) based on the measurements. is manufacture sheet. could include jet speed (144), impingement angle (148), thickness, slice opening, and/or apron projection (142). Adjusting be difference between measured surface. For example, adjusted to achieve desired Multiple headboxes (240-245) controlled, such as when different are used produce layers multi-layer (215).
