ABSTRACT:
A tooling assembly (10) having complementary die sections. Die section (12) includes a face portion (14) having a tooling insert (16) mounted therein. Insert (16) includes an impression configuration (20) formed therein. Flow device assemblies (40) are in communication with impression configuration (20). Flow device assemblies (40) are variably rotatably mounted in die section (12) and are operatively connected to respective flow device actuation assemblies (60). Activation of flow device assemblies (60) can be performed manually, or automatically by, for example, respective conventional motors (90). Motors (90) may be electrical motors each with a driving mechanism attached to a respective flow control device (60). Activation of a flow device actuation assembly (60) causes a respective flow device assembly (40) to rotate and to thereby change its posture of communication with respect to impression configuration (20).
