  • Adjustable profiling head for a wood cutting apparatus
    Patent number: 6688351
    Abstract: An adjustable profiling head for a wood cutting apparatus. There is a first body portion for carrying a plurality of first knives and a second body portion for carrying a plurality of second knives. The cutting edges of the knives define respective cutting surfaces of revolution about an axis that have different mean diameters for the two body portions. In one aspect of the invention, the body portions are adapted to receive the respective knives by associated knife clamping mechanisms that are adapted to be removably mounted to the body portions with one or more first control plates therebetween, for adjusting the radial positioning of the knives. In another aspect of the invention, the body portions are adapted to be removably mounted to each other so that the body portions are disposed axially adjacent one another with one or more second control plates therebetween, for adjusting the relative axial positioning of the knives of one of the body portions with respect to the knives of the other body portion.

  • Method and apparatus for profiling a log
    Patent number: 6637483
    Abstract: A method and apparatus for profiling a log. In a profiler having first and second knives disposed on a rotating disc, a mounting member is adapted to mountably receive both the first and second knives so that each blade has a point on its cutting edge that is proximate a point that is on the cutting edge of the other knives. Preferably, the points are end most points and abut one another.

  • Method and apparatus for profiling a log
    Publication number: 20020043297
    Abstract: A method and apparatus for profiling a log. In a profiler having first and second knives disposed on a rotating disc, a mounting member is adapted to mountably receive both the first and second knives so that each blade has a point on its cutting edge that is proximate a point that is on the cutting edge of the other knives. Preferably, the points are end most points and abut one another.
