Abstract
A method for rewinding a spinning cake from a spinning pot of a pot spinning apparatus onto a rewinding body, preferably onto a tube as a yarn carrier, includes drawing a sliver to be spun in a drafting configuration, guiding the sliver in a pneumatic piecing aid, and depositing the sliver with a traversing yarn guide onto an inner wall surface of the rotating spinning pot as the spinning cake, while maintaining a requisite rotation for formation of a yarn. A yarn guide is moved toward the middle of the spinning cake in a last stroke being shorter than a next-to-last stroke of the yarn guide toward the middle of the spinning cake, once a predetermined size of the spinning cake is reached, before initiating rewinding of the spinning cake onto the rewinding body. A delivery of the sliver from the drafting configuration is stopped once a reversing point of the stroke is reached. The rewinding body is introduced into the spinning pot and the yarn is transferred onto the rewinding body. The rewinding body is raised into a rewinding position. A piece of yarn extending from a tube tip of the rewinding body to the spinning cake in the last yarn guide stroke is wound onto the rewinding body, and the piece of yarn is covered with subsequently wound-on yarn layers.
