A detector that outputs a voltage V 2 proportional to the rotation speed of the side saw wheel, a detector that outputs a voltage V 1 proportional to the circumferential speed of the band saw blade, and the difference between these voltages V 2 - V 1 as a reference Voltage Va
A comparator is provided to compare the output power of the motor with the output of the comparator when slippage occurs between the driving saw wheel and the bandsaw blade and V 2 −V 1 >Va. A safety device for a woodworking bandsaw machine, characterized in that it is provided with a control means for operating a braking mechanism of the driving side saw wheel while cutting the saw wheel.
