The purpose I offer with a continuous training has various meanings. The aim is the creation of a series of operators with the same skills and, at the same time, an interchange that could goes over the training time. To realize it the basic principle is: “theory’s good but practice’s better!”and this really makes me different to those who concentrate all on theoretical lessons. I do also help my collaborators during the practical realization of what I’ ve explained previously. Only in this way operators, products and publics can meet each others.
