The said elements arranged on the front wall have a fold flange for the elements to be coupled with the same elements arranged on the rear wall and to form the blade edge. The blade shape is formed by the second-order line described by a canonical equation. In compliance with the second version, the blade shape is formed by the second-order line described by the canonical equation rectilinear sections. ^ EFFECT: increased life, higher quality of operation. ^ 12 cl, 4 dwg |
