process for the production of elements longilinei bicolori worked 'in circles' and ornamental articles with these elements

摘要

a process in which an element longilineo (1) is made in a cylindrical surface through the processing "in circles", which is coated with the film (2) made of metal of different color.so it is subjected to a processing stage "in circles" in which it is removed, a helical strip of film (2) of the coating.with diamond tools or means to manufacture scabra, creating a saddle element whose surface consists of two strips of a helix coaxial cable.the element longilineo saddle with working "in circles" is then transformed into ornamental articles.
