Abstract: The invention relates to a winding machine, on which, in alternation, a wound package is wound in a winding position of a spindle, while at the same time a completely wound package is removed from another spindle. With winding machines according to the prior art, the completely wound package must be removed quickly before the other wound package has reached a critical diameter to avoid a collision of their lateral faces. According to the invention, a shifting device shifts the completely wound package before or during the winding process of the wound package such that the axial extensions of the wound packages have no overlap. The collision of the wound packages can thus be prevented as the diameter of the wound package increases, whereby a more compact design with a smaller spacing of the spindles is made possible and an operator has more time to remove the completely wound spool.

At least one bobbin receiving site (21, 22) on which a bobbin can be placed is formed on the swivel fork (10). By lifting, lowering and/or swivelling the swivel fork (10) in a specific sequence and repeating same, bobbins can be fed to the processing system (40) and the conveyor system (30) and/or removed therefrom and in this way a bobbin change can be carried out. The conveyor system (30) and the movement area of the swivel fork (10) may be at least partially interpenetrating.
