Modular Design
The patented MLS system allows a light shield to be
assembled in a fast and efficient manner. Extrusions are
cut to the length that is required for the process and
then bolted to endplates to form the primary lightshield
structure. It is completed by the addition of other
standard components that include interior heat shields,
access doors, bottom shielding, and mounting brackets for
the RF detector(s).
Multi-row MLS systems are assembled by joining
individual single row units. A single exhaust duct
connection is required for each single-row or two-row
system.

Standard MLS systems are available for web widths
of 6" - 60", and custom systems can be built for web
widths up to 100". The modular concept is a costefficient
platform for planning future
capacity requirements. It is
necessary to install only the number
of MLS units that will be occupied
with lamp systems. Additional MLS
units may be installed at a time
when production requirements
dictate expansion. The
modular platform offers
a solution that fulfills the
current and future needs
of the end-users in a
timely and affordable
manner.
Lamp Orientation
Shown with quartz window
and bottom water-cooled plate
MLS systems are available to support lamps in any
orientation for processing webs traveling horizontally,
vertically, or at any angle. Bottom-curing configurations
are also available, where the lamps are hung to direct the
light upward to expose the bottom of a horizontal web.
Multi-row systems that require curing top and bottom of
the web are easily configurable.
Bottom Cooling Options
Three bottom shield/cooling configurations are
available for web systems. A bottom heat shield
combined with a bottom plate is recommended for
processing opaque materials or less heat-sensitive
substrates such as paper. For heat-sensitive films, bottom
air cooling is recommended. This is accomplished by
installing a double layer of air-intake (light-tight) louver in
place of the bottom heat shield and bottom plate. If a
heat-sensitive web is being run under low tension and
cannot tolerate air movement, a stainless steel watercooled
plate can be easily installed in place of the double
layer of louver. The design of the bottom extrusions allows
the bottom cooling hardware to be easily assembled in our
factory or changed in the field for process modifications.
