The bench levelling with the rolling device is intended for work on the levelling and rolling of band saws up to 150 mm wide. The feed speed of the feed tape is continuously adjustable, the feed direction is reversed. The principle of operation consists in creating rolling scratches on the surface of the saw when the saw blade is rolled between the drive rollers of the mill. The pressure of the rollers exceeds the yield strength of the saw material and the central part of its blade becomes longer than the edges, which provides compensation for the thermal expansion of the cutting edge of the saw during the sawing process.
