A frame saw, which operates at high speed and is simple in its construction, comprises a set of blades which can be fitted outside the machine and which is fixed in a light frame 40 provided with a to-and-fro motion by means of a drive mechanism. The frame 40 has a guide system 10,20,5c which gives the blades an expedient motional path avoiding blade-stressing peak forces, this being ensured in the lateral direction by guide bars 7, guide pieces bearing against the latter, and blade guides 8. <IMAGE> |
