How Do Pringles Potato Chips Get Their Shape?

Last night before bed, consuming Pringles brand potato crisps (explanation in a moment) while watching some late night TV, I wondered to myself, "How do they make them all perfect?"

The process is somewhat complicated.  In fact, competitors once argued successfully that their high amount of processing and low potato content actually made Pringles technically not potato chips. In 1975, they adopted the name potato crisps, which sounded better than the alternative, 'potato chips made from dried potatoes'.

So how do they actually get their shape?  Instead of trying to explain it in words, I did find one, and only one, video that is a bit strange but does indeed show how Pringles get their shape and how they are packaged.
