Abstract

Hair cutting machine with at least one blade interchangeably supported between a holder plate, blades and a cover plate, the cover plate having a row of teeth covering the cutting edge of the blade, which row of When being driven through the hair, it produces, like a comb, an orientation of the covered hairs in the working direction, that is, perpendicularly to the cutting edge of the blade, and the cover plate and the knife holder plate are movable perpendicular to the cutting edge of the blade, one in relation to the other between two extreme positions and supporting the knife-holding plate to the knife up to the proximity of the cutting edge, but leaving said cutting edge free; characterized in that the blade holder plate, in its area located after the cutting edge of the blade, is structured, next to the outer side of the cutting edge facing the blade, becoming thicker in the form of a wedge from the cutting edge towards back, so that the blade when the machine is placed on the user's head is applied at a cutting angle that is determined by the front ends of the teeth of the cover plate and by the surface or points of placement of the thickening in wedge shape on the user's head; and because next to the two plates, for the relative fixation of these in selectable displacement positions, there are arranged in each case coupling members that are supported under spring pre-tension in mutual application with a desmodromic closure in shape, with one element being supported drive that passes through one of the two plates, accessible from the outside, movably perpendicular to the plane of the blade, which drive element is applied to one of the coupling members, and puts it out of application with respect to the another coupling member when operating against the spring pre-tension.
