B) mixture of the powder obtained, as described with another unvulcanized mixture, of the same technical characteristics and color as the previous one, to obtain a set of little consistency and low coherence, in the form of strands or tufts. C) grinding of said assembly, until obtaining a very fine powder, composed of one or several particles formed by a core of vulcanized form and covered by a raw rubber frame that binds them together. D) filling, with the obtained powder, of the shapes that you want to appear in color or, colors, that you want to obtain in the cavities arranged in the molds, according to the drawings that you want to obtain in relief and with different color to base. E) termination of the mold load, once the filling of the aforementioned cavities has been carried out, with the type of rubber and color corresponding to the base. F) subjection of the mold, once loaded to the usual molding process, that is to say, subjecting it to a pressure, to a temperature and even type of molds, which will depend on the gum mixture that has been used.
