Yuan and Wallace (1973) explained the “Rolling motion” in galactic spiral arms by geometrical means as apparent, but not actual motions. Strauss and Poeppel (1976), however, could demonstrate, that these geometrical effects are not sufficiently large to produce the rolling motions. The aim of this investigation is to explain the remaining part of the rolling motion effect with the galactic fountain model (Bregman 1980).
