FIELD: band saw machines.
SUBSTANCE: invention relates to a device for preventing the band saw blade from coming off the pulley. The device contains a return element, a band saw blade movement sensor, a control unit and a power source. The band saw blade movement sensor is configured to transmit a digital signal to the control unit, which is configured to process the digital signal and transmit the control signal to the power source to connect it to the return element. In this case, the return element is made in the form of an adjustable directional electromagnet, the working surface of the ferromagnetic core of which is configured to cover the pulley rim at an angle to the generatrix of the rim surface and with an air gap narrowing towards the rear edge of the saw blade to create directed electromagnetic forces to return the saw blade to the starting position.
EFFECT: invention increases reliability of the cutting unit of the band saw machine.
