Marek Cholewczynski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9469046
    Abstract: A butt flare reducing apparatus for logs is provided. The apparatus includes a machine frame, a stator ring assembly fixedly coupled to the machine frame, and a flare reducing tool adjustment assembly movably coupled to the stator ring assembly. The apparatus further includes an actuator coupled on one end to the machine frame and on the other end to the flare reducing tool adjustment assembly to move the flare reducing tool adjustment assembly between the opposing end positions, and a rotor assembly rotatably coupled to the stator ring assembly. The rotor assembly includes a rotor frame and at least one flare reducing tool movably coupled to the rotor frame to translate linearly toward and away from a longitudinal axis of rotation in direct correlation to movement of the actuator and flare reducing tool adjustment assembly to adjust a log processing diameter. Related methods are also provided.

  • Patent number: 9073233
    Abstract: Apparatuses, systems, and methods for debarking logs are shown and described. The disclosed embodiments can be easily adjusted to process different logs. Air-cell rings provide for a wide range of force gradients to process both large and small diameter logs. The rings include force gradient adjustment mechanisms configurable to provide different force gradients to process logs.

  • Patent number: 8256476
    Abstract: Apparatuses, systems, and methods for debarking logs are shown and described. The disclosed embodiments can be used for quickly and conveniently replacing contact surfaces, such as leading edges, of-swing arm assemblies (110). Some disclosed embodiments include a swing arm assembly having a replaceable insert (121) that defines a leading edge for engaging logs (130) moving along a processing line. The insert can be made of a wear resistant material for a prolonged life. A worn insert (121) can be replaced with another insert to ensure proper functioning of the debarker.
