ABSTRACT:
For the measuring of saw blades there is created a measuring device which has a receptacle for the turnable bearing of a saw blade as well as a measuring spindle which, with respect to the saw blade, is held adjustable and is born swingably about an axis parallel to the saw blade axis. On the measuring spindle there are arranged two measuring edges which together enclose an angle and are emplaceable on the cutting surface and on the release surface of a tooth. The measuring spindle has a low inertia moment and a friction-free bearing. This arrangement of components permits a simple and dependable execution of the measurement, even by inexperienced personnel, and the measurements of saw blades with different tooth sizes or states of wearing-down.
