Sword saw, has linear saw blades with elastic regions formed during manufacture of blades and exhibiting half circular arch form in cross-section, where regions stretch horizontally towards cutting edge when saw teeth touch hard object

The saw has a container (3) including a motor to drive linear saw blades (2a, 2b) fixed to a scaffolding strut. The blades have elastic regions (20a, 20b) that are formed by a stamping procedure during the manufacture of the blades. The elastic regions exhibit a half circular arch form in cross-sect...

More Information
Summary:The saw has a container (3) including a motor to drive linear saw blades (2a, 2b) fixed to a scaffolding strut. The blades have elastic regions (20a, 20b) that are formed by a stamping procedure during the manufacture of the blades. The elastic regions exhibit a half circular arch form in cross-section. The elastic regions stretch horizontally towards the cutting edge when the saw teeth touch a hard or hooky object e.g. nail. An independent claim is also included for a procedure of producing of a linear saw blade of a sword saw. Bei einem Linear-Sägeblatt (2a, 2b) für eine Schwertsäge (1), dass aus einem in linearer Richtung starren Material gefertigt ist, wird auch bei einer schlagartigen Spitzenbelastung beim Sägen in harte und hakende Gegenstände ein Schaden am Antriebsmechanismus verhindert sowie eine Verletzung des Bedieners verhindert, indem das Linear-Sägeblatt (2a, 2b) in linearer Richtung einen elastischen Bereich (20a, 20b) aufweist. DOLLAR A Dasselbe gilt für eine Schwertsäge (1), die zwei erfindungsgemäße Linear-Sägeblätter (2a, 2b) aufweist. DOLLAR A Ein erfindungsgemäßes Linear-Sägeblatt (2a, 2b) wird besonders preiswert und einfach dadurch hergestellt, dass der elastische Bereich (20a, 20b) während eines Biegevorgangs oder eines Stanzvorgangs zur Erzeugung des Linear-Sägeblatts (2a, 2b) erfolgt.
