Reverse Glass Roll Coater with Conveyor

Reverse Glass Roll Coater with Conveyor

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.

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.

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.

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.
