A tying method and apparatus which is carried to easily automatically band bar-like articles such as reinforcements or pipes and various other articles by a linear tying material. The apparatus comprises tying material feed means (6), tying material bending means (8), encompassing and guiding means (9), tying material cutting means (7) and twisting means (11), wherein a starting point is formed in a way such that a part of a continuous linear tying material w delivered from the tying material feed means comes into engagement with the tying material bending means so that the tying material is bended into a U-shape. In that state, the tying material is delivered from one side whereby the tying material is guided around an article to be tied by the encompassing and guiding means (9) while being bended into a substantially U-shape. The tyingmaterial is cut into a predetermined length, and both ends of the tying material are twisted together by a hook (25) of the twisting means (11). Since the tying material is automatically bended to form two strands and the tying is done only once thereby, the strength of the tying material is enhanced and the rigid tying can be made with a materially strong tying force. Further, since the twisting advances from the hook side toward the article to be tied, the twisting can be advanced till a looseness in the tying portion of the article to be tied disappears, thus enabling the strong tying.
