There is a good hint in the Generic_Kit_Usage_Guide_v2.pdf.

Find it at http://www.bestinc.org, under Participants > File Manager

Then navigate to:
MAIN / Public Resources & Training / Kits

We use them when we want to have a motion that will not perform a complete rotation like an arm that just rotates 180 degrees. You will usually want to use a tensioner to make sure it is good and tight.

Back in our first year, our team spliced the ends together to make a full loop.  They used a section of adhesive velcro (soft side only) on the back and then stitched the belt tight to it with a little of the copper wire (stripped to bare copper).  There was a little hitch when the splice was engaged with the gear teeth, but it worked.  It was in an application where it didn't require a lot of tension.  I can't speak to the the durability of this (I was worried about it) as it was only used on a mall day prototype and was abandoned as the design changed.

Unfortunately, I don't have a close up pic, but you can definitely tell this is not the standard size loop and you can just see the velcro section of the splice.
