Device for the parallel automatic feeding of ornamental chains, in particular for the production of paired chains

摘要

A device for feeding in parallel of ornamental chains to an operative unit of a machine suitable for realizing the bonding of the chains, including a mechanism for the transport of the chains towards the operative unit arranged for the engagement with side by side links of the chains and for obtaining the simultaneous and intermittent advancement without modifying the symmetry of their reciprocal position with respect to the advancement axis. The transport mechanism, comprising in particular needle-shaped members, are provided with a reciprocating translational motion in the forward direction and a reciprocating lifting and lowering motion in an orthogonal direction.
