  • Soldering machine for rope chain
    Patent number: 5115959
    Abstract: An automatic soldering machine for soldering a rope chain comprises a pair of gears, each with a peripheral surface defining a trench which engages one of the strands of the rope chain and which is rotatable to precisely feed and place successive link junctions of the chain relative to hollow solder applying needles. The needles are reciprocally movable and serve to apply a premeasured amount of solder paste at the link junctions of the rope chain. A heater, for example, an induction heater, heats the chain, causing the solder to flow and then set and thereby secure the chain links together.
