In this article, new ruled surfaces Phi s, nu(1) and Phi* (s, a) are obtained for the base lines E-1(s) and E-3(s), respectively. As striction curve is taken as the base curve, distribution parameters of these ruled surfaces with striction scroll are calculated in dual space. As these ruled surfaces are accepted as closed, the apex angles and segments are denoted. An example is given to illustrate the main results. Finally, obtained consequences are discussed.
