Abstract :
In this paper, we first gave the parallel timelike ruled surface with a timelike ruling and its geometric invariants in terms of the main surface. We then obtained the integral invariants which are the pitch and the dual angle of pitch of the parallel timelike ruled surface with a timelike ruling and also the relations among them and integral invariants of the main surface.
