  The study of the formation of bands of drops along the direction of the
vorticity in a concentrated emulsion is presented. That is, the observed
anisotropic structures are characterized by regions of high concentration of
drops interspaced with regions of about equal width where hardly any particles
are present. These particle distributions are a clear departure to what has
previously reported for this emulsion. These patterns are induced by the effect
of a simple flow in circular parallel plate geometry (CSS450-Linkam), but only
after a prolonged time after the inception of the flow. That is, the
observation of bands in emulsions only appears after various other phenomena
occur in the emulsion. That is, the separation of the flow cell plates is 100
\mu m, and the observation of bands occurs within the interval of shear rates
of 3.0 to 5.0 s^{-1}, but only after a long evolution of the initial structure
with a series of flows of 0.75 to 2.25 s^{-1}.
