Process for forming a tubular product consisting of a set of stamped sheet metal modules, assembled together laterally, forming a flexible assembly suitable for bracelets and necklaces for the jewellery and costume jewellery industry

摘要

The present invention relates to a special type of tubular product consisting of a set of stamped sheet metal modules assembled together from a plurality of coupling elements and the same number of coupled elements arranged alternately and in opposing positions in each module, with an appropriate degree of play in the said coupling, such that flexibility in each direction is imparted to the tubular product for the formation of bracelets and necklaces for the jewellery and costume jewellery industry. The said coupling is produced by bringing the modules together laterally instead of vertically by superimposition as is practised currently, thus providing a significant saving of weight by comparison with the conventional systems, in addition to a significantly high rate of output which can be achieved in an industrial way if required, without any limitation as to shape and size.
