ABSTRACT:
An apparatus for cabling wires into a predetermined stranded configuration has at least one first pay-off bobbin rotatably supported inside a carrier, in its turn freely rotating inside a cage-type device and coaxial with it.
The cage is supported to rotate about its own axis.
Part of the wires constituting the produced cord can be drawn through the apparatus coming from a second, external to the apparatus, pay-off bobbin.
The carrier comprises means for guiding the wires along a path developed from one extremity and/or from the first pay-off bobbins to the other extremity of said carrier, said path being not coincident with the axis of the apparatus, and means, disposed along said path, for permanently deforming the wires by bending.
