Abstract

An extrusion apparatus including a flex lip and a reciprocally movable actuator bar for adjusting the lip gap, is disclosed. Axial movement of the actuator bar advantageously results in control across the full width of the lip gap. In one aspect of the invention, a handwheel or motor is positioned opposite the output end of the extrusion apparatus. In another aspect of the invention, a rotatable shaft of a control assembly is beneficially disposed generally perpendicular to direction of movement of the actuator bar, and advantageously a portion of the shaft is received within an endplate of the extrusion apparatus. In a variation, a control assembly simultaneously exerts a pulling force on one end of the actuator bar and a pushing force on the opposite end of the actuator bar.
