A delivery device for traveling thread for textile machines having a storage drum to which the thread is fed in a rearward region by a thread guide tube which revolves around the storage drum and from which the thread is withdrawn overhead through a thread withdrawal eye. An automatic threading of the thread is effected by compressed air such that the thread is blown through the thread guide tube, deflected at its exit mouth side parallel to an outer surface of the drum and conducted on an end side thereof below bristles of a displaceable brake ring which forms a slot with the outer surface of the drum, radially inwardly into a region of a tip of a head cone, the tip being directed towards an opening in the thread withdrawal eye formed as an axial suction-blast nozzle. A curved surface extends in a thread blowing direction into a horizontal surface deflecting the thread at the exit mouth side of the thread guide tube with the latter being obliquely upwardly directed during the automatic threading. The nozzle effects a radially inward deflection directed towards the nozzle of an end of the thread flying free in a plane vertically above the nozzle exclusively by a stream of suction air along an outer surface of the head cone. The outer surface of the head cone extends in the plane and forms a linear guide surface for the end of the thread, the linear guide surface extending from the outer surface of the drum to the tip of the head cone.
