<p>The invention relates to a dry-shaving apparatus comprising a housing (1) with a holder (2) for a shear plate (3) formed with hair-entry apertures (5) and comprising a cutter (4) which is rotatable about an axis of rotation (11), which cutter (4) comprises a carrier (12) with cutting elements (8) which are movable in a substantially radial direction relative to the carrier (12), which cutting elements (8) comprise cutting edges (10) at their radial ends (9). During rotation of the cutter (4) as part of a revolution each point of the cutting edge (10) of a cutting element (8) follows a constrained path defined by the shear plate (3) and when the ends are clear of the shear plate (3) a free path in the form of a larger circular arc. At the location where the free path changes into the constrained path between the peripheral portion and the central portion the shear plate is formed with a transitional portion having a larger radius of curvature than the central portion.</p> |
