ABSTRACT:
A method of transferring full packages in a spinning frame having a plurality of spinning stations arranged in a row on each longitudinal side of the frame, a single run package transferring conveyor disposed between the opposite rows of the spinning stations and a doffing unit which provides doffing service at each spinning station while traveling around the machine, is provided herein. The doffing unit performs its doffing service at a station which calls for doffing of its full package only when a package is absent on the conveyor at a position corresponding to the station at which the doffing unit is then stopped, but it defers its doffing operation at the station if a package is present at said corresponding position on the conveyor. The conveyor is caused to move when the number of those packages which are undoffed due to deferment amounts to a predetermined value.
