Abstract

This invention is concerned with a procedure for obtaining bi-coloured long components with which to manufacture jewellery, therefore addressing the field of precious metal working. According to the invention, on a support plate (1) a groove (2) is made in precious metal, on which first of all a layer of solder is melted, then a strip of precious metal (3) is inserted, which will be joined to the one below by fusion of the said solder. The plate produced is rolled and possibly plated with non-precious metal until the required thickness has been reached. The said strip can be cut lengthwise at the centre until an upper strip is obtained consisting of two components of a different colour. The strip, if entirely of precious metal, can feed machines for producing jewellery or be pinched around an internal support made of non-precious metal and finally, when plated, drawn and brought to the required size with which to feed machines and produce chains or other jewellery (figs. 1 and 7).
