ABSTRACT:
A dry-shaving apparatus comprises a longitudinally extending shear plate provided with hair-entry apertures; and an associated longitudinally extending cutter rotatable about an axis of rotation, such cutter including a spindle coaxially positioned with respect to the axis of rotation. The shear plate has a central portion shaped as a part of a cylindrical surface and formed with the hair-entry apertures, the central portion partly surrounding the cutter. Cutting elements movable relative to the cutter in a substantially radial direction are provided, each cutting element having a cutting edge at its radial end. More than two coaxial discs are axially spaced from each other and are formed with slots extending in a substantially radial direction, the coaxial discs being rigidly mounted on the spindle. Each cutting element has oppositely disposed axially projecting connecting portions for insertion of the cutting element into facing slots in two adjacent discs, the connecting portions being movable inside the slots in a substantially radial direction.
