摘要： 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 inclination between the frontal edges (48, 148) of the hair-entry slots (46, 146) and the radial direction (96, 196) is in a range from 35° to 60°; wherein a shearing angle (δ), defined as a difference between the slot angle (a) and an angle of inclination (β) of the cutting edges (64, 164) of the cutter blades (62, 162) with respect to the radial direction (96, 196), is in a range from +20° to −20°; and wherein the shearing angle (δ) is defined at an actual point where the frontal edges (48, 148) and the cutting edges (64, 164) cooperate.

摘要： The invention relates to a shaving unit for a shaving apparatus, comprising at least a first cutting unit (110a) and a second cutting unit (110b), wherein said first and second cutting units respectively comprise a first and a second external cutting member (114a, 114b) having a plurality of hair entry openings which respectively define a first and a second shaving track (161a, 161b), and a first and a second internal cutting member which is rotatable relative to, respectively, the first and the second external cutting member about a first and a second axis of rotation (106a, 106b), respectively, wherein the first cutting unit is pivotal about a first primary pivot axis (101a) which, seen in a direction parallel to the first axis of rotation, is arranged between the first shaving track and the second axis of rotation, and wherein the second cutting unit is pivotal about a second primary pivot axis (101b) which, seen in a direction parallel to the second axis of rotation, is arranged between the second shaving track and the first axis of rotation.
