PCT No. PCT/EP80/00040 Sec. 371 Date Mar. 10, 1981 Sec. 102(e) Date Mar. 2, 1981 PCT Filed Jun. 30, 1980 PCT Pub. No. WO81/00264 PCT Pub. Date Feb. 5, 1981.The present invention concerns a method of automatically doffing the full bobbin packages from, and donning the empty bobbin tubes onto, the spindles of a preparatory spinning machine equipped with flyers. The flyers are of the so-called suspended type, i.e. they are rotatably supported in a flyer head. For the conjoint, vertical doffing of the full bobbin packages, and for the conjoint, vertical donning of the empty bobbin tubes the flyers are pivoted to the side in such manner, that they cannot obstruct the doffing of the full bobbins any more. The inventive preparatory spinning machine comprises a common support beam in which the flyers are rotatably supported, in which arrangement the beam can effect a translatory movement in such manner that each flyer can be brought into an inclined position.
