Chipboard Coding
Definition of Task
- Edges of chipboards with lengths from 15 to 21 meters (50 to 69 feet) are marked on the side directly after the sanding machine
- Print information is the manufacturer name, the production location, the emission character, the exact production date and time
- Print height is 5 mm (0.2 inch) for small and 10 mm (0.4 inch) for large chipboards
Special Product Specification
- Chipboards are cut into two or three pieces and are then stacked, the individual coding of the edges has to represent a closed and well readable lined up print image
- Conveyer which transports the chipboards past the print head accelerates, from approx. 60 m/min (200 ft/min) on up to 90 m/min (295 ft/min), during the coding process
- Ambient temperatures are relatively constant at around +46° Celsius (115° Fahrenheit)

Advantages of the REA JET Solution
- In order to maintain a constant distance between the chipboards with the various sizes and formats and the print heads, REA designed a distance balance device to automatically adjust the distance between the print head and the chipboard
- To eliminate the slip effect of the shaft encoder wheel, which occurs with the contact of each new chipboard, a specially designed encoder bracket was installed to apply pressure to prevent contact slip between the encoder wheel and the material surface
- Coth print heights are allocated by scripting language
