Abstract:
1. An apparatus, comprising: a die having at least one applicator slot in fluid communication with a die cavity, wherein the die cavity exhibits a length, a width and a volume; and an expansible chamber device disposed within the die cavity, wherein the expansible chamber device exhibits an initial volume less than the volume of the die cavity when an applicator liquid is introduced into the die cavity, and wherein the volume of the expansible chamber device increases from the initial volume to an expanded volume less than the volume of the die cavity in response to an increase in pressure of an incompressible liquid within the expansible chamber device, and decreases from the expanded volume in response to a decrease in pressure of the incompressible liquid within the expansible chamber device; and control means for controlling the volume of the expansible chamber device by increasing and decreasing the incompressible liquid pressure within the expansible chamber device.
