ABSTRACT:
The method disclosed envisages embodiment of a solid back carrying tufts of bristles or fibers etc which is provided, at least along the stretches near its outermost ends, with a series of sloping lands having an angle of inclination that is progressively less accentuated the nearer a single land is located to the middle section of the surface on which it is formed. Each land is provided with a corresponding hole whose axis is disposed normal or substantially normal to the land, whilst the remaining part of the surface is provided with uniformly-distributed holes the axes of which are either normal or marginally inclined relative to the surface itself. At least one tuft is set into each hole in such a way that the projecting tips of the bristles or fibers lie within a common plane.
