BUTT FLARE REDUCING APPARATUS FOR LOGS AND RELATED METHODS OF REDUCING BUTT FLARE Russian patent published in 2019 - IPC B27C5/08 B27L1/00 

FIELD: woodworking industry.

SUBSTANCE: group of inventions relates to the woodworking industry, in particular to the reduction of butt flares of logs. In the method, the device comprises a stator ring assembly fixedly connected to the machine frame and a flare reducing tool adjustment assembly movably connected to the stator ring assembly. Further, an actuator is coupled to the flare reducing tool adjustment assembly to move the flare reducing tool adjustment assembly longitudinally between the opposing end positions. Also a rotor assembly rotatably coupled to the stator ring assembly. Said rotor assembly includes a rotor frame and at least one flare reducing tool movably connected to the rotor frame. Each log is measured in front of a plurality of the flare reducing tools. For each subsequent log, the specified radial position of the flare reducing tool is determined on the basis of the used log diameter obtained from measurements. For each successive log, the position of each flare reducing tool is adjusted according to the corresponding flare reducing tool trajectory in order to correspond to a given radial position in order to reduce the flare of the log.

EFFECT: increased efficiency, reliability and safety of adjustment of processing diameters of logs.
