摘要: A method includes generating a model associated with cross-directional fiber orientation of web, which identifying spatial frequency characteristics (FO) process. The also providing the for control FO Generating could include performing impulse test process, and long wavelength responses process can be identified by or retrieving information from historical database. Actuator edge padding applied to in order generate controller model. used based on At least one parameter dynamically adjusted during operation controller. change average angle profiles twist only adjusting slice lip actuators headbox.
