Query: Does rotation generate a massive string ?   The properties of a stationary massive string endowed with intrinsic angular
momentum are investigated. The spacetime is generated by an "improper" time
translation combined with uniform rotation. The mass per unit length of the
string is proportional to the angular velocity $\omega$. The spacetime is
Minkowskian geometrically but the topology is nontrivial thanks to the event
horizon located on the surface $r = 0$ (similar with Rindler's spacetime) and
to the deficit angle generated by rotation. The Sagnac time delay is
calculated. It proves to be nonvanishing even when $\omega = 0$ due to the
intrinsic spin of the string.
