摘要： A machine (1) and a method (100) for producing links of an ornamental chain, of the type comprising a plurality of concatenated links, by using a filiform semi-finished product (S). The machine (1) comprises a deformation and cutting means (10) configured to separate one section (S') from the remaining part of a filiform semi-finished product (S) and to bring about a first deformation of the section (S') so as to define a central arch-shaped portion and two end edges of the section (S'). The machine (1 ) further comprises a closing means (14) configured to bring about a second deformation of the section (S') so as to bring the end edges near or in abutment against each other. Furthermore, the machine (1) comprises a welding means (20 and 21) configured to weld together the end edges brought near or in abutment against each other and disposed in a welding area (A), wherein said welding means (20) is configured to generate two or more laser light beams (22) suitable for welding the end edges, generating respective distinct welding spots on the contact perimeter.
