Abstract:
1. A method comprising: receiving, via an interface, a measurement of an anisotropy of a first surface and a measurement of an anisotropy of a second surface of a sheet of material; determining, using a processing unit, whether a curling potential of the sheet being manufactured is within target values for curl based on a difference between the measured anisotropy of the first surface and the measured anisotropy of the second surface; and in response to determining that the curling potential of sheet being manufactured is outside the target values for curl, adjusting, using the processing unit, at least one operating parameter associated with a headbox based on the difference, the headbox associated with manufacture of the sheet; wherein adjusting the at least one operating parameter comprises adjusting a projection of a slice apron in the headbox to thereby alter a point of impingement and an angle of impingement associated with a jet of material in the headbox.
