Abstract: A device in connection with a cutting machine with an annular saw blade and with a driving mechanism for off-center drive of the blade. The device includes two first rollers arranged to contact and roll against the web of the saw blade on one side of the blade and two second rollers arranged to contact and roll against the web of the blade on the other, opposite side of the blade. The first rollers are mounted on a first shaft, which is movable along a path against the plane of the saw blade, perpendicularly to the centerline of the shaft, for pressing the first rollers with a certain desired force against the blade web under counter force by the second rollers on the opposite side of the blade.
