Corrugator/extrusion die dead to mold continuous corrugated tubing

A semi-liquid tube extrudes into a moving set of mating mold blocks on 'caterpillar tracks' guiding the mold blocks and continuous air pressure down the center of the die's mandrel blows the tube in the corrugations which chills the tube. The mold blocks separate as they move around their track producing continuous corrugated tubing that you will see in a variety of products including the emergency room and surgery documentaries seen on TV.

And here's a close-up view of the drawing.
