Roller coater

Machine for applying paint, stain, oil or wax to flat workpieces during throughfeed.

Function principle

The liquid coating material is pumped into the roller system between the application roller and metering roller. The material is divided up evenly through the gap between the two rollers. Changing the gap width facilitates varying the application volume. The material that has adhered to the application roller is now applied to the workpiece as it is fed through.

Characteristics

  • Realisable layer thicknesses between around 5 and 100 g/m²
  • Feed rates of up to roughly 40 m/min
  • No coating of the narrow surfaces possible

For bigger application quantities curtain coater are employed.
