<p>Any dirty rotor (1) which is a part of an open-end spinning machine in a first phase is automatically localized, withdrawn and replaced with a clean rotor (1a) taken from a storage point for clean rotors, the purpose being to reduce to a minimum the time needed for the re-starting of spinning on the unit in question, while at the same time another phase is carried out in which the rotor or rotors withdrawn and replaced are thoroughly cleaned and, after being cleaned, are stored.</p> |
