REVERSE GLASS ROLL COATER
WITH CONVEYOR
We're In The News!
Union Tool's Reverse Roller Coaters
are featured in a spandrel glass coating article
in Ceramic Industry magazine
A reverse roller coater for application of UV paint, solvent-based
and water-based paints to glass plates, panels and sheets. This Union
Tool reverse roll coater has integral infeed and outfeed conveyors for
direct integration with new or existing production and processing lines.
SYNONYMS
Depending on your application, this unit might be referred to as a
UV paint applicator, a glass roll coater, glass paint coater, glass
reverse roller coater, in-line roller coater, glass paint spreader,
or inline UV roller coater.
ROLL CONFIGURATION
In the Model C-rev Single Reverse Action Top Coater
Roll Configuration, the liquid coating for the top surface is held
in the trough between the top coating roll and its companion doctor
roll. In this configuration, however, the top coating roll is rotating
against the direction of substrate movement; this is the "reverse
coating action" that results in a very smooth and even coating, which
is especially desired in coating glass and similar substrates. The
bottom roller simply drives the substrate through the
machine.
OPERATIONAL DESCRIPTION
The Union Series #5, Model C 14" Roll Coater was specifically designed
to apply a smooth and controllable amount of UV paint to the top surface
of glass substrates for solar applications such as lighting fixtures.
By incorporating an infeed and offbearing conveyor, this roller coater
can be placed right in the production line.
The conveyor connects a wash/rinse operation with a UV oven to dry
the UV-coated substrates. This is a reverse-action roller coater, which
produces a very smooth coated surface. An explosion-proof motor and
electricals have been added due to the use of flammable cleanup solvents.
A variable speed drive unit allows for increased production without
losing coating quality.
