Abstract

A saw blade (10), in particular for band saws, is moved through a measuring path and a rolling path in a direction of travel (A) which essentially corresponds to its longitudinal direction, with two marginal regions of the saw blade (10) being supported on the measuring path-and held down in a start portion and an end portion of same and thus being held in a common reference plane which contains the direction of travel (A) and the saw blade (10) being lifted above the reference plane by a supporting force which is exerted only in the central area of the measuring path. The profile of the saw blade (10) is then measured in a measuring plane (B) which extends orthogonally to its direction of travel (A) in the center area of the measuring path, with data of the profile height relative to a chord which extends transversely to the direction of travel (A), coordinated with data of the distance of the measuring points from an edge (14) of the saw blade (10) and data of the longitudinal movement of the saw blade is stored. The saw blade (10) will be rolled in the direction of travel (A) region-by-region in accordance with this data.
