Abstract
The disclosure relates to an apparatus including a die having at least one applicator slot for translating an applicator liquid through the die. The slot is in flow 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. The applicator liquid is translated through the die and delivered from the applicator slot at intervals corresponding to actuation 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 is an incompressible liquid.
