Abstract
A banknote centering device uses a drive arrangement to accelerate two opposed side plates and the inertia of the side plates causes the banknote to be centered. The resistance of the banknote to buckling stops the side plates. A separate drive for the side plates accelerates the side plates and stalls when a banknote is centered. Preferably, the current for the drive of the side plates is variable to adjust for changing conditions.
