How old is that serpantine belt?
Age can cause this, it may even come from slippage. Is the outside very shiney? You may also have a damaged pulley that is responsible for damaging the edges. You could also have a problem with one of the accessories coming loose, and trying to twist the belt. You can verify this by removing the tension from the belt, and giving a good tug on the individual accessories, a loose one will be obvious.
