<p>A method of preventing a wire from becoming entangled in a reinforcing bar fastening machine having a wire feed device for feeding a wire (1) for fastening reinforcing bars (b), a guide arm (3) for guiding the wire (1) so as to wind around a crossing point of the reinforcing bars (b) in the form of a loop, a twisting device (4) for performing a tying operation by twisting while picking up part of the loop of the wire (1) wound around the crossing point of the reinforcing bars (b) and a cutting device for cutting (6) the loop from the wire (1) on a reinforcing bar fastening machine side, the method comprises the steps of: monitoring a torque of a motor (6) for driving the twisting device (4); and stopping the operation of the twisting device (4) when no increasing tendency is observed in changes in the torque after a predetermined time has elapsed from an operation start timing of the twisting device. <IMAGE></p> |
