Abstract
A method of controlling a slot die comprises, while continuing to pass the extrudate through the fluid flow path and out the applicator slot, changing the position of the actuators with the controller to either increase the cross-directional thickness of the fluid flow path adjacent each of the actuators or substantially close the fluid flow path adjacent the actuators, and after changing the cross-directional thickness of the fluid flow path adjacent each of the actuators, while continuing to pass the extrudate through the fluid flow path and out the applicator slot, repositioning each of the actuators with the controller according to the set of discrete settings to resume operating the slot die with the actuators positioned according to the set of discrete settings.
