Jewelry link forming apparatus |
摘要 |
A jewelry link made from square crossectional metal wire has a C-shape when the link is bent within a specially configured clamp over a smooth, uncut mandrel, wherein the formed C-shaped links are diamond shaped in cross section. The links further have an outer circumference at their widest point formed by one of the four corner seams of a hollow or solid square wire, which is rotated 45 degrees onto one of its straight longitudinally extending edges before being bent around a smooth mandrel. In that manner, the link is considerably wider than a link formed from square wire which is wrapped upon one of its surfaces over a mandrel.
