ABSTRACT:
An apparatus for rendering automatic the production of ornamental chains of the kind known as "partridge's eye", wherein two link elements shaped as a turn are linked to form a link of the chain so that the free ends of one are roughly at the center of the other. The link is compressed transversally and axially to cross the end portions of the two link elements, so that the free ends of one element come into contact with the internal contour of the other. The link formed in this way is twisted, at its ends, welded in correspondence with the overlap points of the two link elements, and then linked to a link element suitable to form the subsequent links. The apparatus for producing this kind of chain, operating according to this process, includes a pair of vices for taking up and linking the link elements, and for engaging the link formed with a further link element, a forming mechanism for the link suitable to compress the coupled link elements both transversally and axially, a welder for connecting the link elements at the overlap points, and a mechanism for producing the link elements.
