Abstract
An easily controllable method to adjust the die slot exit gap to produce an accurately controlled flow from the slot exit across the width of a die provides movable back seats at the back of the die that cause the front and back portions of the die plates to move simultaneously to produce a change in the die slot exit gap. At least one actuator is located between the front and back seats of the die to increase or reduce its length to bend the first plate around the front seat thereby to increase or decrease the first exit gap.
