The adapter (8) carrying the draw-off tube (17) and the fiber feed channel (11) is carried on the spinning box lid (6). The adapter has a finger-like extension (22) which has a stop (18) that registers directly on the rotor housing (3). The stop (18) is located on the side away from the swing axis (5) of the lid (6). The mating surface of the stop can be adjusted by inserting circular shims.
