Abstract (en)

[origin: WO2022123294A1] A method of adjusting a slot die is provided, the slot die having an applicator slot extending across a width of the slot die, wherein the slot die comprises opposed first and second slot die surfaces, and wherein the applicator slot is in fluid communication with a fluid flow path through the slot die. The slot die includes first and second adjustment mechanisms operatively coupled to the first and second slot die surfaces, respectively. The method includes assigning a target setting for the first adjustment mechanism based on a pre-selected cross-web profile for an extrudate; with that target setting, determining a slot height profile corresponding to a plurality of locations along the opposed first and second slot die surfaces; predicting, with a controller, a set of discrete settings from a plurality of discrete settings based on both the slot height profile and the pre-selected cross-web profile, the prediction based on a known correlation between the set of discrete settings and a cross-web profile of the extrudate; and setting a position for each of a plurality of actuators coupled to the second adjustment mechanism according to the predicted set of discrete settings.
