    Patent number: 5215135
    Abstract: A new type of fuel pellet and method and apparatus for manufacturing. Pellets are cut directly from logs without requiring grinding and extruding. A veneer type lathe and rolls hold a log and the rolls incise the log surface to a depth larger than the veneer cut prior to cut off with the veneer knife so that all three dimensions of the pellet are precisely controlled as well as being clean cuts.
