Abstract
The invention relates to jewelry chains by electro-forming wherein a jewelry chain as an original material is thickened by an electro-forming to obtain fattened chain links thereof such that the fattened chain links not only make the distance between interlinked pivotting points of each chain link of the chain relatively smaller to make the chain in a denser construction but also adapt the chain for subsequent various processes such as pressing, swaging and the like to obtain more novel chains in design and style. Further, it relates to an apparatus suitable for the electro-forming process.
