Abstract
The disclosure relates to a method for forming a die having an applicator slot for translating an applicator liquid through the die. The slot is in fluid communication with a die cavity. An expansible chamber device is disposed within the die cavity and changes volume in response to changes in fluid pressure within the expansible chamber device, which may be regulated by a means for controlling the volume of the expansible chamber device. In some embodiments, the die has a single rectangular applicator slot, and the expansible chamber device is an expandable cylindrical tube disposed within the die cavity. In other embodiments, the fluid within the expansible chamber device may be selected to be a compressible gas. In further embodiments, the fluid within the expansible chamber device may be selected to be an incompressible liquid.
