The concept of biframe related to frames, was introduced as a pair of sequences. In this paper, the effect of operators on biframes preserving the biframe property is discussed. The relationship between a frame and its duals in forming a biframe is investigated. Finally, the dual frames of two frames that form a biframe are studied and some interesting results are obtained.
