Summary:PURPOSE:To obtain a multiple decorative chain having two-tone spiral pattern by inserting an inner material of metallic wire different in quality from an outer material into the inside of the outer material of metallic pipe, drawing the assembled wire into an angular wire rod of fine diameter and linking ring bodies with a wire rod having an inside exposed by shaving the side in the shape of many rows of chains. CONSTITUTION:Raw material 3 of large diameter through which the inner material 2 of metallic wire different in quality from the outer material 1 is drawn continuously by many dies on the inside of the outer material 1 of a metallic pipe to obtain a wire rod 4 of fine diameter. Then, the sides 6, 6' of the wire rod 4 of fine diameter are shaved to obtain an inner material exposed wire rod 7 where the inner material 2 is exposed on the sides 6, 6'. Ring bodies 8 are linked with the inner material exposed wire rod 7 in the shape of many rows of chains to obtain a multiple decorative chain 9.
