  Recently, large families of two-dimensional quantum field theories with
factorizing S-matrices have been constructed by the operator-algebraic methods,
by first showing the existence of observables localized in wedge-shaped
regions. However, these constructions have been limited to the class of
S-matrices whose components are analytic in rapidity in the physical strip.
  In this work, we construct candidates for observables in wedges for scalar
factorizing S-matrices with poles in the physical strip and show that they
weakly commute on a certain domain. We discuss some technical issues concerning
further developments, especially the self-adjointness of the candidate
operators here and strong commutativity between them.
