An extrusion apparatus including a flexible lip for adjusting the lip gap, and including reciprocally movable members in operative contact with the flexible lip is described. Beneficially, a generally laterally movable actuator bar is connected to angled slots of the reciprocally movable members by pin members rotatably mounted in bores of the actuator bar. Lateral movement of the actuator bar advantageously results in lip gap control across the full width of the lip gap. Use of reciprocally movable members with slots of selected angles provides for profiling the lip gap. Also provided is an advantageous mechanism for controlling movement of the actuator bar and reciprocally movable members.
