DOUBLE HEAD ROLLER COATER

This heavy-duty roller coater has two coating heads, for applications requiring a heavier coating layer than would normally be possible with a single-head machine of the same size.

SYNONYMS

Depending on your industry, you may call this a double-headed roll coater, a dual head roll coater, a heavy spread coater, a double coat roller coater, a twin head coater, a double head coater, a dual head heavy spread coater, or a thick-spread double coater. (Baseball fans tend to refer to it as a "double header" ...)

ROLL CONFIGURATION

In the Model C Single Top 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 bottom roller simply assists in feeding the substrate through the machine. This Double Head Roller Coater has two of these Model C roll units in series.

OPERATIONAL DESCRIPTION

For applications requiring a heavy coating, Union Tool has designed the Double Head Roller Coater. The Double Model C Roller Coater shown is designed to apply a rubber compound to paper gaskets. To ensure that enough coating is applied, gaskets are conveyed through two separate coating heads, coating both the top surface and the edges. Some coating material collects on the conveyor belt in this process, so a powered brush system cleans the belt. Both coating assemblies, the powered conveyor and cleaning brush are driven by the same motor. Although this double head roller coater uses the same coating in both heads, each coating assembly could contain different coating materials.
