Pilot coater continuous web coating system for
product and process research and
development. The system uses coordinated
sectional DC variable speed drives to maintain
precise tension on the web as it is transported
through the coater process. Basic system
involves DC variable speed drives with encoder
feedback for speed regulation of the unwind
roll, the tension section (coating section) and
the rewind section or wind-up roll. The
machine can be operated in either tension or
speed control modes. This machine ultimately
developed products that became the roof of the
Denver International Airport, London Millenium
Dome, the Georgia Dome Olympic Stadium and the
lining of NASA Space Shuttle cargo bays.
