Reverse Roll Coating Equipment
Walco 609RS and 610 DRS Spandrel Glass Coaters

The Walco 609RS Spandrel Reverse Roll Coaters economically and consistently applies smooth “spandrel” coatings to architectural glass. Also known as a as a spandrel glass roller coater, the Walco 609RS is sometimes called a glass coater, a glass paint applicator, a roll coater for glass, a glass painter, or a glass paint coater. This is the ideal reverse roll coating system for applying the following architectural glass coatings:

  • OPACI-COAT™ 300 Silicone Glass Coating
  • Ceramic frit enamel

Safety is built into every Walco Spandrel Glass Reverse Roll Coating Equipment. Hinged in and outfeed nip guards are interlocked to the main motor drive. Trip the hinged guard? The motor immediately stops. Electrically interlocked upper roll guards disable the main drive motor if opened while operating.

All Walco Roll coating equipment is custom tailored to customer requirements. Design considerations include specifying length, width, thickness, speed, temperature, pressure, materials, weight of coating, and/or finish. Walco design and engineering teams work with customer teams from start to finish to ensure each unit meets the client operational and safety requirements. No Surprises!

Reverse Roll Coater

The Walco 609RS Reverse Roll Coater is designed to provide the user with:

  • Ease of operation and very easy cleanup. The Walco 609RS is on pedestals, creating a much easier washdown.
  • Quick roll change out. Powered conveyors have capability down to 8’” x 8’’ glass light samples.
  • Ability to shear (fine tune coating). Individual drives are located on the top and bottom roll, speeding up or slowing the top roll shears the coating accurately.
  • Ultimate in and outfeed conveyors x 10.0 feet long: speed is matched to the Coater drive, synchronized exactly.
  • Easy clean up with small (0.5” diameter) individual belts vs. large width conveyor. Round belts make for a much easier cleanup.
  • Built to work effeciently with all glass products including: insulating glass, laminated glass, architectural glass, tempered glass in standard colors or with custom color
  • In and outfeed conveyors that are mechanically connected to lower drive roll horizontal adjustment–keeping “flop” to a minimum.
  • Ability to explosion proof if needed.
  • Variable frequency drives for speed control (on standard machines)

Walco 609RS Reverse Roll Coaters are available standard widths of 76”, 86” and 104”. Contact us for complete equipment specifications.
