Method of producing a staple fiber yarn

A two stage method of centrifugally spinning a staple fiber yarn comprising the steps of:

• in a first spinning stage:
• drawing a feed material by a drafting device;
• and
• depositing the drafted feed material onto an interior surface of a spinning centrifuge via a yarn guidance tube axially shiftable therein while twisting the drafted feed material between the drafting device and the interior surface of the spinning centrifuge into a partially twisted yarn;
• and
• in a second spinning stage:
• withdrawing the partially twisted yarn from the spinning centrifuge while further twisting of the partially twisted yarn into a fully twisted yarn and winding the fully twisted yarn onto a cheese by a winding device;
• wherein shortly prior to completion of the first spinning stage:
• placing a prepared end of a previously finished yarn unwound from the cheese onto the feed material at the drafting device;
• joining the prepared end of the finished yarn to the partially twisted yarn of the first spinning stage;
• separating the feed material at the joinder between the prepared end of the finished yarn and the partially twisted yarn;
• then changing the direction of travel of the partially twisted yarn;
• and
• then initiating the second spinning stage by withdrawing the partially twisted yarn from the spinning centrifuge.
