Automated Coating Machines: Industrial Roll Coaters


These automated liquid coaters (also called "roll coaters" and "roller coaters") are specifically designed for directly applying virtually any liquid coating to the top and/or bottoms of clean, flat and dry sheet stock, wood, glass, acrylic, plastic, sheet metal, webs, wovens, non-wovens and the like. Over 300+ upgrade modules allow Walco to tailor each machine specifically to meet your operational and safety requirements. WALCO’s Automated Roller Coaters are the result of over 50 years of engineering for simple and reliable operation.

Walco’s direct action series of automated liquid coaters come in both medium and heavy duty versions. All are available in whatever width meets your requirements, plus multiple standard operational and safety features.


Automatic roll coater

Automated roll coating applications can include:

  • Glue Spreading
  • Clear Top Coating
  • Color Coating
  • Painting
  • Oil Coating
  • Reverse Coating
  • and more...

  • Precision adjustments allow exact metering of the coating liquid for uniform coating, saving time and money. The roll opening is adjustable – any thickness of stock from .001" to 1.5" (Special wide opening coaters are available). The coating liquid is poured into the reservoir formed by the coating roll and the doctor roll. By adjusting the doctor roll away from the coating roll, the thickness of the coating liquid is regulated.

    There are two automated roll coater versions available:
