Patent attributes
The invention relates to a cutting device (1) for cutting hair, having at least two blades (2, 3) which move back and forth relative to each other. The blades (2, 3) are provided with teeth (8, 9) which extend transversally to the direction of movement (P), and tooth gaps (25, 26) arranged therein. The teeth (8, 9) have contact surfaces (4, 5) on their facing sections which are in gliding contact with each other and which form cutting edges (34, 35) on their sides bounding the tooth gaps (25, 26) such that the back and forth movement (P) of the blades causes the tooth gaps (25, 26), cooperating with each other, to form constantly changing cutting gaps (32) in which hair becomes clamped and is finally cut. According to the invention, the free ends of teeth (9) of one blade (3) project over sections (15) of free ends of teeth (9) of other blades (2), and projections (17) extend from the projecting sections (15) of the teeth (9) on the contact surfaces (5) side. The projections (17) improve the cutting result by erecting the hairs lying flat against the skin surface (29) during the cutting process, feeding them more easily to the teeth (8, 9).
