Straight edges, curved edges – Biesse has a zero glueline solution for the edgebanding of both
With more and more manufacturers upping their game and increasing the quality of the products they make, it’s not hard to see the appeal of a zero glueline.
There are numerous ways to reduce an unhygienic and unsightly glueline between the edging tape and the surface of a board but, unless you’re going to encapsulate the entire board with a coating, there’s only one way to eradicate it completely: fuse the two together so there is no join.
Biesse offers two solutions: Airforce for straight panels; Rayforce for curved components. Airforce is Biesse’s hot air fusion system for straight line edgebanding operations and it works very simply by blowing hot air at a temperature of between 520 and 580 degrees onto a co-extruded edging tape.
The heat melts the co-extruded adhesive layer, affixing it to the edge of the board, and simultaneously welds the edge of the tape to the decorative material on the top surface to create an absolutely seamless finish.
“The important point to make here is that you must use a co-extruded edgebanding tape to get a zero glueline,” says Malcolm.
To cope with the heat on its Airforce-equipped machines, Biesse has replaced the more usual infeed device that cuts the tape and leaves it in place with an automatic tape feeder that retracts the edgebanding after it's been fed and cut so it doesn’t melt. The added benefit is that when you change edging reels, you don’t have to open the door.
Malcolm also confirms it’s very easy to use an Airforce-equipped edgebander.
