CONTINUOUS SOLDERING METHOD AND DEVICE FOR NOBLE METAL OR NOBLE METAL PLATED CHAIN

摘要

A method and apparatus are provided for soldering abutting ends of links of chains of precious metals. The soldering is accomplished by applying solder to the abutting ends, continuously feeding the chain onto a rotating surface such as a rotating table, heating the chain to melt the solder, and removing the chain from the table. The chain is fed at a slightly higher rate than the rational speed of the table to cause the links to be pushed into each other to avoid tensions from developing in said links during the heating step.
