ABSTRACT:
A machine for the production of decorative chains made up of links of different forms and/or dimensions connected according to any programmable sequence, comprising at least two independent formation stations (1, 1') in alternate operation according to a prefixed, alterable program on the basis of the features of the chain to be manufactured, and a take-up unit (14), for transferring the chain from one station to another according to said program. Drive means for said take-up unit (14) are provided in each station for actuating the opening and closure of pliers (27), carried by said unit (14) during chain take-up and delivery phases, for producing an axial movement of said unit (14) to and from said stations in coincidence with said phases and for producing an angular displacement of said unit (14) with respect to its axis during said phases. Finally, said drive means enable the station to release the last formed link to said take-up unit (14).
