摘要： A piercing machine for marking writings, numbers and the like on metallic curved surfaces, such as the ogive-shaped portion of steel cylinders, which allows for the marking by engraving also of symbols varying from one piece to be marked to another, without hand substitution of the piercer elements. The piercers are disposed and held on a disc along a spiral arrangement. This disc may be operated and driven into rotation by two independent mechanisms, one for the engraving of the symbols which are always the same, and the other for the variable symbols. The first mechanism causes and intermittent mono-directional rotation movement, while the second mechanism causes a continuous rotation, in both the senses. The disc bearing the piercers can be brought into rotation alternatively by only one of said two mechanism, but in any case, during its rotation, it is also subjected to a rectilinear translation which, combined with the rotation, is such that the piercers disposed along a spiralshaped line, are always aligned with a hammering means the operating axis of which is stationary.
