Automated butyl coating station for spacer frames

Butyl extruder for precision butyl coating on both sides of spacers. Sensor-controlled guide rollers ensure optimal stabilisation of the frame and therefore ensure an even coating. The opening and closing cycles of the coating nozzles for each frame side are controlled automatically. An integrated measuring device measures the frame widths and ensures that the nozzles are continuously adjusted from 6 to 24 mm. The coating speed can be individually selected.



  • Progressively adjustable working height
  • Processing of spacer frames with and without Georgian bars
  • Easy coating of round arches and shapes
  • Coating area can be extended up to 42 mm
