A PERFECTED PLATE-ROTLE, of which they are constituted by a full laminar body, characterized essentially by the fact that the signs are obtained by transverse partial displacement of the mass included within the profile of the sign, in such a way that approximately one half , of said mass protrudes through one of the faces of the flat laminar body, thus determining a hole in the opposite face, equal to the protruding mass; the sides of the relief and the hollow being perpendicular to the surfaces of the plate and one being an extension of the other.
