Definitions

• the invention relates to a method for producing a profile strip, in particular edge strip, with different decorative elements.
• profile strips of the material mix aluminum and veneer wood are known for this application.
• Such a profile strip is shown in Fig. 1.
• Conventionally, such profile strips are manufactured in a complicated process by first plate-shaped layers of aluminum and veneer wood are glued together. Subsequently, this layered plate is cut into strips. For better processing and fixation, one or two webs can be glued to the back of the edges.
