Fundamentals of Edge Processing

Draught or a too low room temperature will cool down the adhesive at the glue applicator roll before it can join edging and board.

Tip: Check the adhesive temperature at the glue applicator roll with an infrared thermometer as well. If you are wearing a jacket at work, that is too cold. An ideal workshop temperature is 18 - 20 °C.

When boards and edgings are stored in unheated rooms in winter, or when they come from a cold truck, the adhesive's open time is often already exceeded while still in the machine. The adhesive cools down fast on the boards, until it can no longer build enough adhesive power.

Tip: Both materials should therefore be stored in a heated workshop for 24 hours before processing.

With some machines, you have to manually adjust the retaining device at the edging feed to the respective edging height. If it is not sufficiently fixated, the edging will warp when glued on.

Perform a tear-off test before every new project in order to check all process parameters.

• tear off the edging from the board immediately after application in a 90° angle
• some chips should be pulled out of the board
• essential is the adhesion strength between edging and board

Sure - there is no such thing as a dust-free workshop. This is precisely why you should regularly maintain and clean the machine.

• remove dust and swarf with a vacuum cleaner
• use compressed air only in areas that are otherwise difficult to reach

Tip: If you often process high-gloss or super matt surfaces, you should clean the machine parts and in particular the transport tracks with a suitable product. That prevents dust and dirt from settling in the still fresh glue joint.

For a perfect result store the edgings ...

• in a light-protected and dust-free place, i.e. in a closed cabinet
• horizontally: the edging roll stays dimensionally stable, which secures its later processing
