Abstract
A method for operating a pot spinning machine which has a plurality of identical work stations each having a drafting device with a slubbing stop device, a spinning centrifuge rotating at high speed around an axis, and a tubular reciprocable guide. A slubbing emerging from the yarn guide mouth forms a rotating yarn leg which is deposited on the inner wall of the spinning centrifuge in the form of a spinning cake. At the start of a spinning cycle of the spinning machine, the individual spinning centrifuges of the spinning machine are checked for the presence of yarn cake remnants.
