Claims23
Circular sawing machine, comprising a supporting surface for the workpiece and a saw blade projecting from said supporting surface in a region of an opening of the supporting surface, said saw blade being held and driven by a drive flange and said saw blade being pivotally mounted for said saw blade to be pivotable to both sides in the region of said opening relative to a plane at right angles to said supporting surface, said drive flange including a drivable spindle flange and a mating flange co-operating with said spindle flange and being detachable therefrom, two holding parts hinged together for pivotal movement and a first holding part of said two holding parts carrying said spindle flange and a second holding part of said two holding parts carrying said mating flange, with said two flanges being rotatably mounted, said two holding parts being pivoted with respect to each other and pressed together by a force exerted by at least one spring in such a way that said saw blade is held between said spindle flange and said mating flange by the force exerted by said at least one spring.
