The large-scale unipolar zones have boundaries which practically coincide with filament bands encircling the whole Sun. Huge currents flow in these filament bands, which attract or repulse each other. When new unipolar zones are generated near the equator and thus new filament bands appear after a while. The previously existing filament bands feel a new repulsion/attraction and their pole-ward motion starts. When a filament band reaches a pole and disappears (pole reversal) it releases the amount of "surface mass" it was holding and this pushes the other filament bands somewhat back, causing a "recoil". A more or less stationary situation may result as e.g. in the second half of the sunspot cycle (after a polar reversal), in wich the filament bands move slightly back and forth of their "equilibrium" latitude. Numerical estimates give reasonable acceleration and velocities, provided the filament bands are loaded by much more mass they carry themselves: indeed they are anchored in the regions of unipolar field and thus form a connected piece like a sheet which may slip over the Sun.
