Abstract: A shaving appliance and a shaving unit are described. The shaving unit has a rotary cutter having a plurality of cutter blades that are provided with a cutting edge. The shaving track includes hair-entry slots that, seen in the direction of movement, have a frontal edge and a rear edge. A slot angle (?) defined as an angle of inclination between the frontal edges (48, 148) of the hair-entry slots. A shearing angle (?), defined as a difference between the slot angle (?) and an angle of inclination (?) of cutting edges of cutter blades with respect to the radial direction. The shearing angle (?) is defined at an actual point where the frontal edges and the cutting edges cooperate.

Abstract: The present disclosure relates to a shaving appliance (10) and to a shaving unit (24), the shaving unit (24) comprising a rotary cutter (30, 130) comprising a plurality of cutter blades (62, 162) that are provided with a cutting edge (64, 164), the rotary cutter (30, 130) being arranged to rotate about a rotation axis (26, 126) in a direction of movement (36, 136); a guard cap (28, 128) having an annular shaving track (44, 144) surrounding the rotation axis (26, 126) for cooperation with the cutter blades (62, 162), the shaving track (44, 144) being provided with hair-entry slots (46, 146) that, seen in the direction of movement (36, 136), have a frontal edge (48, 148) and a rear edge (50, 150); wherein the frontal edges (48, 148) of the hair-entry slots (46, 146) are, in a cutting portion (70, 170) along the long side extension of the hair-entry slots (46, 146), inclined with respect to a radial direction (96, 196) extending from the rotation axis (26, 126), wherein a slot angle (a) defined as an angle of in

Abstract: A hair cutting device (10) is provided comprising a cutter unit (11), a skin stretcher (12) and slit adapting means. The cutter unit (11) comprises a skin-contact surface for dragging over a skin surface (21) in a shaving direction (55), a front surface arranged in front of the skin-contact surface in the shaving direction (55), and a laser beam exit window arranged in the front surface for allowing a hair cutting laser beam (13) to cut a hair (22) near the skin surface (21) in front of the front surface. The skin stretcher (12) is positioned in front of the cutter unit (11), according to the shaving direction (55), and comprises a stretcher surface for dragging over the skin surface (21) together with the skin-contact surface, such that a skin dome (23) is formed by the skin surface (21) in a slit between the skin stretcher (12) and the cutter unit (11). The slit adapting means are provided for adapting at least one dimension (51, 52, 54) of the slit for controlling a shape of the skin dome (23).
