Abstract
A pot spinning assembly comprises a spinning pot and a yarn guide extending into the spinning pot. A controlled drive causes a relative motion between the spinning pot and the yarn guide during a spinning process. Yarn is deposited in layers on the inner wall of the spinning pot and a spinning cake is formed. The spinning pot is displaced along its longitudinal central axis between an upper end position and a lower end position. An outlet opening of the yarn guide is located in the vicinity of the lower edge region of the spinning pot when it is in the upper end position. A yarn holder for receiving yarn from the spinning pot, and a substantially horizontal transport apparatus for moving the yarn holder to the spinning pot for rewinding the spinning cake onto the yarn holder is provided. The transport apparatus moves the yarn holder away from the spinning pot when it is in the upper end position.
