ABSTRACT:
The disclosure relates to the art field of machines for crafting jewelry, namely, chains both in precious metal and in costume jewelry metals. The apparatus of the present invention includes an indexing mechanism for feeding at least one wire, a cutter for severance of the wire into discrete lengths, a horizontal link former that can move transversely relative to the direction the wire is being fed, and a vertical pincer the grips of which are designed to loop the longitudinal member around the entire cross-sectional periphery of the link former in such a way that the ends of a length of wire, formed into a link exceed the peripheral length of the link thus manipulated. The pincer moves through a path parallel to the link former and into a position where soldering means are located that fuse together the end stretched portions of excess length of the link into a bead, thereby embellishing the finished link.
