A method, in a spinning machine comprising a spindle portion and a nozzle portion having a first nozzle for exerting a turning air current on a fiber bundle moved out of a drafting device, comprises introducing a yarn end on the package side from the spindle portion into a second nozzle to place it in an open state, turning the yarn end around the spindle by jetting a low pressure air from the first nozzle, and supplying the drafted fiber from the nozzle portion to effect a piecing. A piecing apparatus in the spinning machine comprises device for sucking a spinning yarn wound into a package, device for reversing the package, device for guiding and cutting the sucked spinning yarn, device for transferring a spinning yarn to an outlet side of a spinning yarn of a spindle member separated from a nozzle member of a spinning section, and movable device for threading and opening on a sliver inlet side of the spindle member of the spinning yarn.
