Sounds correct. It's where the pellet gets it's shape.
It's also the large ring on the ring pelleter.

This is a form of pelleting. Think it's called the hydraulic ram pelleter. 
It's mainly used for metal shavings from lathes and mills. Kind of slow. 

There is also the mechanical piston pelleter and some people have made them 
from a hay balers. But in regards to biomas fuel, this pelleter suffer from 
variations in copact density and the fuel is not as good as from a screw 
press or I would think ring pelleter.
