Each saw blade is provided with a stretch angle and a hydraulic tension unit comprising at least one cylinder and one piston. The tension units have levers which exert a tractive force on the stretch angle by being turned around a rotary point by the hydraulic tension units. Adjacent hydraulic cylinders are displaced relatively to each other in a lateral direction viewed in the saw blade width direction, and/or in a height direction, and this enables a tight fit to be achieved. |
