with a fiber-coupled 2 kW diode laser and a special optic
which maps a highly homogeneous linear focus along the
edging band. The polymer edge is melted on one side
directly before the feed point to the narrow face of the
wood panel and is then compressed by rollers. The
surface heating with the laser is followed by rapid cooling,
so the joint is strong enough for immediate post-
processing. Based on that method, IMA Klessmann
GmbH, a leading international manufacturer of production
plants for the furniture industry, launched the technique of
laser edge banding by diode laser. Processing of various Material: Edging tape with absorbent functional layer
