Abstract
A hair-cutting apparatus is provided which has an external cutting member (1) and an internal cutting member (7) which is drivable relative to the external cutting member. The external cutting member has lamellae (3) between which hair-entry apertures (4) are formed, and the ends of the lamellae form teeth (9) for raising hairs before the hairs are cut. To increase the efficiency of hair catching the teeth are given different lengths. Preferably, there are long teeth (9a, 9b) and short teeth (91, 92) which alternate with one another.
Claims2
A cutting apparatus having an external cutting member and an internal cutting member which is drivable relative to the external cutting member, which external cutting member is formed by a first wall portion, which constitutes a cutting face, and at least a second wall portion, which is disposed at an angle with respect to the first wall portion, which first wall portion has lamellae between which elongate hair-entry apertures are situated, ends of the lamellae extending beyond the second wall portion in such a manner that the ends of the lamellae form a row of teeth for raising hairs to be severed between the cutting members,
- wherein the teeth have different projecting lengths with respect to the second wall portion and comprise a first type of teeth and a second type of teeth, the first type of teeth being long teeth having a larger projecting length when compared to the second type of teeth, and
- wherein, viewed in a longitudinal section of a lamella, an apex angle of a tooth of the first type is smaller than an apex angle of a tooth of the second type.
A cutting apparatus having an external cutting member and an internal cutting member which is drivable relative to the external cutting member, which external cutting member is formed by a first wall portion, which constitutes a cutting face, and at least a second wall portion, which is disposed at an angle with respect to the first wall portion, which first wall portion has lamellae between which elongate hair-entry apertures are situated, ends of the lamellae extending beyond the second wall portion in such a manner that the ends of the lamellae form a row of teeth for raising hairs to be severed between the cutting members,
- wherein the teeth have different projecting lengths with respect to the second wall portion and comprise a first type of teeth and a second type of teeth, the first type of teeth being long teeth having a larger projecting length when compared to the second type of teeth, and
- wherein viewed in a longitudinal section of a lamella, the tooth tips of the teeth of the second type have a smaller radius of rounding than the tooth tips of the teeth of the first type.
