SYNONYMS
Depending on your industry, you may call this a roller coater, a roll
coater, heavy-duty coater, or a heavy-duty roller coater.
ROLL CONFIGURATION
In the Model B Double Coater Roll Configuration, the liquid coating for the top surface is held in the trough between the top coating roller and its companion doctor roll; the liquid coating for the bottom surface is held in a pan in which the bottom coating roll and its companion doctor roll both run.
OPERATIONAL DESCRIPTION
The Union Series #45 Roller Coater was designed for customers who require
an extremely rugged, dependable roller coater. The 8.75" diameter coating
rolls and 6.5" diameter doctor rolls are constructed of extra-heavy
wall tubing and are mounted in heavy-duty, anti-friction, self-aligning
ball bearings. The heavyduty construction allows the Series #45 to be
built in widths ranging from 12" to 98". Coating speeds up to 600 l.f.p.m.
are possible while applying a smooth, even, controllable coating to
a wide variety of sheets or coils.
Standard construction features include a single handwheel to adjust
the upper coating head in a vertical plane (0-2") in order to compensate
for various substrate thicknesses. Two hand knobs move the doctor roll
bearing assemblies in relationship to the coating roll to adjust the
amount of coating being applied. All coating and/or backup rolls are
powered through a chain drive, complete with spring-loaded takeups.
Standard safety features include a reversing drum connected to a safety
cable around the perimeter of the coater to reverse the direction of
the powered rolls in the event of an emergency. Sheet metal guards with
expanded metal inserts enclose the upper coating head. The drive system
as well as all moving parts are shielded with guards or covers to protect
the operator.
