**Abstract:** Abstract. We interpret the results of the
preceding paper (I) in terms of partial resummations of the perturbative series
for the effective interaction. As an application we sketch how our resummation
method leads to a simple summation rule leading to a convergent expansion for
the Schwinger functions of the planar $\phi_4^4$-theory.
