<p>A device for tensioning a series of removable saw blades into a beam for use as a multi bladed cutter has a flange (16) incorporated in at least one end of each blade (12). The tensioning flange (16) has a circular section surface in the longitudinal saw blade (12) direction into which the tensioning nail or claw (10, 18) engages and which retains the blade. The curvature of the flange permits some angular displacement between the saw blade (12) and the tensioning nail or claw (10, 18).</p> |
