  • the edge-banding machine 1 thus enables workpieces 2 to be edge-banded in a precise and accurate manner without ruining the workpieces being machined, i.e. without damaging the final aesthetic appearance thereof.
  • the encoder 37 can be mounted coaxially to a supporting shaft of the driving roller 13, or to a respective supporting shaft of the second idle roller 15, and thus not on the supporting shaft of the first idle roller 14.
