Saw blade with concentric collar

摘要

The saw blade (1) has a screw connection acting on one side against a ring face and with slight tension of the screws (5) is inclined plate-shaped in the active direction of the screws so that it can be brought with an increasing screwing force into a flat plane. The saw blade can be screwed against a convex intermediate ring face or fixed flange with convex ring face. The saw with convex collar has a convex collar face. The saw blade can have an outer ring zone inclined towards the collar.
