These 12-station
units consist of an 8-station chassis with a 4-station trailer
section, including an in-line Rosbach
"chopper." The choppers are basically in-line guillotines that
can remove the back spine from a booklet to create individual
pieces. This allows for 50+ inserts. The
Rosbach units can simply be disengaged when not needed, or the
entire trailer section can easily be removed in less than 5
minutes.
