My take:
As with most Carrara users some times you can stubbornly spend more
time than is profitable just to figure out how to do it in C - even
when a faster solution could be had using something else.
Harvey's formula idea sounds like an elegant way to get what you need.
With my math skills I have to rely on brute force animation to get it
done.
With that in mind here is one way to crack that nut that might be
more trouble than its worth.
But... once you've got all the issues worked out it could be a fast
way to do future projects that need a similar effect.
Feed an animated height map to an Anything Grooves modifier applied
to your conveyer belt.
You can even use Carrara to make the map.
I hacked out this sample in about 30 minutes (from making the map to
rendering the moving belt).

(I think I flipped the normals on one section but the over all effect
is still there)
Timing could be tricky but since you are making your own height map
you would have a lot of options for control.

could be used for animated tank or dozer tread too.
