According to the invention, the machine comprises a marking tube magazine supported rotating on an axis, and a feeding device for moving, by one ring at a time, any one of said marking tubes towards a delivering point in which each individual ring is broken off. The machine comprises moreover a ring-gripping and tearing member, capable of automatically tearing and positioning each ring in front of a hollow needle movable from a backward position to a forward position with respect to the gripping member; and furthermore comprises a device for transferring each ring or combination of rings from the needle onto a wire, inserted into the same hollow needle.
