Abstract

A saw blade (10) is supported on a saw blade carriage (14) adapted to be adjusted by an adjusting drive means (18) along a carriage guide means (16) and cooperating with a distance measuring means (26,28,30). A sensor means (34) is disposed in the path of movement of the saw blade (10) and emits signals in response to the position of a front edge portion of the saw blade (10) extending transversely of the carriage guide means (16). The adjusting drive means (18) is controlled by these signals and stopped at a predetermined nominal position of the front edge portion of the saw blade (10). In this manner the saw blade (10) positioning is effected automatically and the positioning accomplished permits a conclusion to be drawn with respect to the diameter of the saw blade (10) so that no separate measurement thereof is required.
