Abstract (en)
[origin: WO2022123295A1] Provided are methods of operating a slot die having an applicator slot extending along a width of the slot die, wherein the applicator slot is in fluid communication with a fluid flow path through the slot die, and at least one of a group consisting of: a choker bar and a flexible die lip. The choker bar or the flexible die lip shape can be manipulated by applying, with a force application mechanism, forces that are generally parallel to the width of the slot die. Further provided are methods of operating and purging a slot die, where at least a portion of the applicator slot is blocked with one or more deckles to reduce an effective width of the applicator slot.
