Apparatus for detwisting wires or cables wound in spools

An apparatus for detwisting wires or cables wound in spools, the apparatus comprising:

• two coaxial shafts, inserted one inside another and kinematically independent, of which a first shaft is connected to first motor means and is adapted to support one of said spools by rotating said one of said spools about a rotation axis, and a second shaft is connected to second motor means and supports a detwisting cage by rotating said detwisting cage about said rotation axis, said detwisting cage being configured to rotate about said spool with at least one guide for said wire or cable that is being unwound from said spool;
• at least one take-up guide for said wire or cable, which is connected to third motor means in order to rotate about said rotation axis of said detwisting cage, oscillating toward said at least one guide and/or away from said at least one guide;
• and
• means for coordination of the rotation speed of said first shaft with a rotation speed of said take-up guide.
