Abstract
A method of controlling a slot die comprises positioning actuators of the slot die with a controller according to a first set of discrete settings, operating the slot die by passing an extrudate through the fluid flow path and out the applicator slot with the actuators positioned according to the first set of discrete settings, and while passing the extrudate through the fluid flow path and out the applicator slot, changing the positions of the actuators with the controller to create patterned features in the extrudate.
