摘要

An apparatus for discontinuously and simultaneously soldering an ornamental chain on two locations and with recovery of the cores which hold the loops, comprises a reel (2) for winding and unwinding the chain to be soldered, a pair of rollers (3,4) for advancing the chain, a movable and rotating vice for carrying the chain to the soldering device. The latter comprises two flame injectors, arranged opposite one to the other and acting on the loops of the chain, a pair of vertically movable clamps for holding the chain during the soldering operation, in the two predetermined locations. Finally after the soldering operations, the cores are removed from the chain and are separately collected.
