ABSTRACT:

The invention relates to a plate link for attaching a clasp link to an ornamental chain. An object is to make such a link safer.
The invention also covers a method of attaching the end of a chain to a clasp link by means of a plate link. This method involves the use of electrically welding the plate link and is carried out in the absence of weld material.
The present invention provides a plate link attaching a clasp link to the end of an ornamental chain, characterized in that the link is electrically welded without any weld metal, thus ensuring maximum hold even against considerable force applied to the chain and the clasp link. Because the link is closed by electric welding, it prevents the clasp link or the end of the chain from becoming detached in any way.
