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.

Abstract translation: 一种控制狭槽模头的方法包括：在连续地将挤出物通过流体流动路径并从施加器槽中通过的同时，改变致动器与控制器的位置，以增加流体流动路径的横向厚度 或者基本上关闭与致动器相邻的流体流动路径，并且在改变与每个致动器相邻的流体流动路径的横向厚度的同时，继续使挤出物通过流体流动路径并且从施加器狭槽出来， 根据一组离散设置，使用控制器重新定位每个致动器，以根据一组离散设置使致动器定位，以恢复操作槽模。
