Trifolding
The first fold is done between the bifold rollers. The process of the first fold is the same with the bifold process, but
the fold is done at a different position. The paper is fed to the trifold rollers for the second fold.
The motor (bifold guide) drives the trifold diverter. The bifold rollers feed the paper so that the folded edge is between
the trifold diverter and trifold knife.
