  Within the framework of algebraic quantum field theory, we propose a new
method of constructing local generators of (global) gauge symmetries in field
theoretic models, starting from the existence of unitary operators implementing
locally the flip automorphism on the doubled theory. We show, in the simple
example of the internal symmetries of a multiplet of free scalar fields, that
through the pointlike limit of such local generators the conserved Wightman
currents associated with the symmetries are recovered.
