A method for starting the operation of a friction spinning machine, including friction surfaces movable in opposing directions for forming a spinning wedge; the friction surfaces being movable in a spinning direction during a spinning operation, a device for supplying fiber to the spinning wedge, at least one suction device acting on the spinning wedge, a suction tube supplied with suction air, and a thread withdrawal device includes: stopping the fiber supply and the motion of the friction surfaces; stopping the suction; moving the suction tube through the spinning wedge in a given direction for sucking in thread and fiber remains; subsequently sucking a thread through the suction tube; moving the suction tube out of the spinning wedge in a direction opposite said given direction depositing the thread in the spinning wedge; resuming the suction at least as late as the step of moving the suction tube out of the spinning wedge; moving the friction surfaces in a direction opposite the spinning direction removing the twist of the thread and loosening the thread; subsequently stopping the motion of the friction surfaces again; starting the fiber supply again; moving the friction surfaces in the spinning direction with increased speed; and coordinating and increasing the fiber supply, the motion of the friction surfaces and the thread withdrawal until a normal spinning operation is established, and an apparatus for carrying out the method.
