Abstract

Two clamping jaws (30, 32) disposed opposite each other and operable by fluid pressure are connected to each other by gearing (38, 40, 50) which guides them symmetrically with respect to a central plane (B). The gearing (38, 40, 50) comprises two racks (38, 40) meshing with a pinion (50) disposed between them and each secured to a respective one of the clamping jaws (30 and 32). The axis (48) of the pinion (50) is adjustable transversely of the central plane (B) to change the location thereof. In this manner any saw blade (10) may be clamped in the area of each individual tooth (12) exactly symmetrically with respect to the central plane thereof.
