A carbon infrared heating
system from Heraeus
Noblelight is reported to have
enabled Smith & Mclaurin to
more than double line speed
and improve quality on one of
its paper coating lines.

One of Smith and
McLaurin’s products requires
a water-based adhesive to be
applied to high value stock
before a laminate is applied to
the adhesive. Previously, the
adhesive was dried in a warm
air oven but this sometimes
caused problems when drying
coloured adhesive.

To solve the problem
Heraeus installed a 32.5kW
infra-red heating system
equipped with five carbon
medium wave emitters
immediately before the
existing warm air heaters. The
emitters are individually
controlled so that they can be
switched on and off according
to the coating weight.
