The apparatus has two blades coupled with respect to each other and provided with spaced triangular or trapezoidal cutting teeth, where one of the blades is movable for cutting a wood engaged between the teeth by shearing and connected to a brushless electric motor (13). An electronic board (14) for controlling the motor is arranged to detect movement of the mobile blades and to control an inversion of the direction of rotation of the motor instantaneously and automatically. The electronic board controls the inversion of a displacement direction of the mobile blades. |
