Claims
- 1. A cutting unit for a shaving apparatus, which cutting unit comprises a cutting head with hair entrance apertures and a drivable cutting member the hair entrance apertures being separated by dams extending substantially transversely to a direction of driving (P) of the drivable cutting member and having a first end and a second end, wherein in cross-section a dam has an asymmetrical profile with a thickness which increases stepwise in the direction of driving (P) from said first end to the second end of said dam.
- 2. An electric shaving apparatus comprising a cutting unit having a cutting head with hair entrance apertures and a drivable cutting member, the hair entrance apertures being separated by dams extending substantially transversely to a direction of driving (P) of the drivable cutting member and having a first end and a second end, wherein in cross-section a dam has an asymmetrical profile with a thickness which increases stepwise in the direction of driving (P) from said first end to the second end of said dam.
- 3. A cutting unit for a shaving apparatus, which cutting unit comprises a cutting head with hair entrance apertures and a driveable cutting member, the hair entrance apertures being separated by dams extending substantially transversely to a direction of driving (P) of the driveable cutting member and having a first end and a second end closest to the direction of driving (P) wherein in cross-section a dam has an asymmetrical profile with a thickness which increases in the direction of driving (P) from said first end to the second end of the dam.
- 4. A cutting unit as claimed in claim 3 in which each dam is substantially trapezoidal in cross-section.
- 5. An electric shaving apparatus comprising a cutting unit having a cutting head with hair entrance apertures and a driveable cutting member, the hair entrance apertures being separated by dams extending substantially transversely to a direction of driving (P) of the drivable cutting member and having a first end and a second end closest to the direction of driving (P) wherein in cross-section a dam has an asymmetrical profile with a thickness which increases in the direction of driving (P) from said first end to the second end of the dam.
