  • Apparatus for manufacturing rings
    Patent number: 4689464
    Abstract: An assembly apparatus for assemblying rings comprises a support (10, 11, 12); and a ring shank holding stud (20) connected to the support, the stud (20) including an electrically conductive portion for receiving a metallic ring shank thereon. An electrode (44) is coupled to the ring setting through a collet (52) which engages the ring setting, for supplying electrical current to the setting. A ring shank holder (14) fixedly holds the ring shank in a pre-determined position relative to the ring shank holding stud (20), whereby the ring shank and setting are held in a pre-determined fixed position relative to each other. Electrical current is supplied to the electrode (44) and to the ring shank holding stud (20) so that the electrical current passes through the setting and the ring shank so as to weld the setting to the ring shank.
