Title
(EN) Shaving apparatus as well as a cutting unit for such a shaving apparatus
Abstract
(EN)

A shaving apparatus provided with at least one cutting unit including external and internal cutting members drivable relative to each other. The internal cutting member includes at least one cutting element with a cutting edge movable along a cutting path while being driven in a driving direction. The external cutting member includes at least one hair-entry aperture bounded by at least first and second wall portions of the external cutting member, at least the first wall portion having a cutting edge for cooperation with the internal cutting member cutting edge. An edge portion of the second wall portion facing a plane along the cutting path, in a cross section taken substantially perpendicularly to the plane along the cutting path, touches a virtual circle in at least two contact points on the virtual circle.
