<p>A method of straightening a knife (1) for a root slicer, whereby a knife (1) is straightened, which in the straightened state comprises a plate-shaped securing member (5) as well as a corrugated cutting blade (4) connected to said securing means, the crests and troughs of said corrugated cutting blade being positioned between two parallel planes, whereby the securing plate (5) and the corrugated cutting blade (4) are mutually staggered to their respective side relative to a common plane (8). During the straightening process, the securing plate (5) and the corrugated cutting blade (4) of the knife (1) are separately retained and then subjected to a bending process about a longitudinal line (2, 9) extending substantially in the common plane (8) inside a transition zone (2) between the corrugated cutting blade (4) and the securing plate (5). An apparatus for carrying out the method comprises clamping means (13, 17) clamping the corrugated cutting blade and clamping means (28 and 29) clamping the securing plate. The latter clamping means (28, 29) are pivotally mounted about a line (25) of rotation, and by turning about said line the knife (1) is subjected to a bending towards the top side (70) and subsequently the bottom side (71) and finally backwards towards the top side (70) to a predetermined degree.</p> |
