ABSTRACT:
A method for producing indicative and/or decorative tridimensional pieces, e.g. types, digits or the like, comprising providing a beam having a normal cross-section reproducing the outline of said piece, and cutting said beam along a least two parallely spaced planes, in order to obtain single pieces having a desired thickness. The beam is preferably a drawn metallic or extruded plastic beam and the cutting operation thereof may be carried-out along planes forming a suitably selected angle, different than 90.degree., with the beam axis, to obtain single pieces having modified size ratios in respect to the beam normal cross-section.
