Abstract (en)
[origin: WO9748508A1] Method for manufacturing cutting blades (16) for a mower, especially a so-called cyclo mower, whereby departing from a material strip (10) of which the thickness corresponds to the thickness of the cutting blades, and of which the width corresponds to the length of the cutting blades, successive transections are made approximately in transversal direction across a significant part of the width of the strip such that the section of the strip between two successive transections forms a cutting blade, and that suitable tools (18, 19) are used such that simultaneously with the transection operation a shaping operation of the edge(s) (17) of the blank is performed resulting into a cutting blade having ready made cutting edge(s).
