To do. Therefore, when the shape of the fruit is spherical, if the radius of curvature is too large compared to the radius of the peeled hole, the depth of the fruit entering the peeled hole will become shallow, and the blade will eat into the fruit! It's shallow! Furthermore, if the object to be peeled is cylindrical or conical like carrots, for example, the side is almost straight, so that the side completely crosses the peeled hole in the radial direction. The blade cannot engage with carrots.

Abstract

Couteau d'épluchage réalisé en équipant une plaque de métal d'un trou d'épluchage. Le bord périphérique comprenant une section d'arc circulaire (12b) du trou (12) d'épluchage réalisé dans la plaque métallique (10) comporte un dépassement (13). Le dépassement (13) est réalisé par travail à la presse provoquant une zone travaillée à la presse entourant le bord périphérique incluant la section d'arc circulaire (12b), dépassant de telle manière que la hauteur du dépassement par rapport à la surface métallique soit plus grande que celle d'une section d'arc circulaire (12a) faisant face à la section d'arc circulaire (12b). La pointe du dépassement (13) est coupée en parallèle avec la plaque de métal pour réaliser un bord (14). Le bord n'est pas réalisé à la section d'arc circulaire (12a) qui est plus basse en hauteur que la section d'arc circulaire (12b).
