摘要： There is provided an emergency braking apparatus for stopping travel of the blade of an electrically powered saw of the type incorporating a cutting table through which the blade of the saw passes during a cutting operation. The apparatus comprises a braking jaw and a movable jaw spaced apart from the braking jaw for reception of the blade of the saw between the braking jaw and the movable jaw. The apparatus also comprises a driver for driving the movable jaw from a retracted position into contact with a side face of the blade to force an opposite side the blade against the braking jaw and thereby clamp the blade between the braking jaw and the movable jaw, a pressure chamber for holding a fluid at a predetermined pressure, and an actuator operable in response to an emergency braking signal to release the pressurised fluid in the pressure chamber to drive the driver against the movable jaw whereby the movable jaw is driven into contact with the side face of the blade.
