Abstract
A die for dispensing a fluid onto a substrate, wherein the die has an movable lip adjacent a fixed lip to form a die opening therebetween. An actuator is mechanically connected to the movable lip and is operable to automatically move the movable lip with respect to the fixed lip in association with a fluid dispensing process, thereby changing a volume of the die opening. The adjustable die is often a slot die and is used with a fluid dispensing valve having an upstream valve ball. The actuator can be an electromechanical actuator such as a piezoelectric actuator or a fluid operated actuator.
