  • Ladder tape for window covering and slat adjusting apparatus using the ladder tape
    Patent number: 8496041
    Abstract: A ladder tape includes two pairs of warp strings, and two weft strings repeatedly passing through the warp strings in a predetermined way to form two cords and a plurality of bridge sections between the cords. The weft strings respectively are wound around one section of each pair of the warp strings only to form an opening between the warp strings that the ladder tape may engage with the rotary drum of the window blind in a fast and easy way. The weft strings are wound around the warp strings in a way that the ladder tape will not get entangled with other objects unexpectedly.
