Abstract
A method is provided for producing a laminar male die of the interchangeable type, for printing Braille characters on yielding supports. The method includes the step of punching the metal foil that forms the body of the male die to obtain a plurality of first points in relief on a first face of the foil. The first points define one or more characters in Braille alphabet. The method further includes punching the metal foil to obtain at least two second points in relief on the other side of the foil; the second points in relief are aligned with corresponding receiving seats of an outer male die-holding support. A male die obtained by the method and the respective manufacturing apparatus are also described.
