摘要：A ladder tape (10) includes two pairs of warp strings (11-14), and two weft strings (15, 16) repeatedly passing through the warp strings (11-14) in a predetermined way to form two cords (10A, 10B) and a plurality of bridge sections (15c, 16c) between the cords (10A, 10B). The weft strings (15, 16) respectively are wound around one section of each pair of the warp strings (11-14) only to form an opening (10a, 10b between the warp strings (11-14) that the ladder tape (10) may engage with the rotary drum (20) of the window blind in a fast and easy way. The weft strings (15, 16) are wound around the warp strings (11-14) in a way that the ladder tape (10) will not get entangled with other objects unexpectedly.
