A window shade deployment system comprising: a pair of tracks adapted to be located opposite each other and attached to the sides of a window opening; a window shade of the pleated type, one end of said shade affixed to a portion of the window frame, each side of said shade having therein a slot engaging with one of said tracks as said shade is moved over said opening; a header secured to the opposite end of the shade and mounted transverse the sides of said frame, said header having a motor and electrical circuitry mounted therein, said motor providing motive power to traction drive wheels for the purpose of propelling said header over said pair of tracks; at least two pairs of traction drive wheels rotatably secured to the header, one pair engaging each of said tracks, each wheel pair having an interior wheel adapted to travel on one side of the track and an opposing, closely biased exterior wheel adapted to travel on the other side of the track, at least one wheel in a wheeled pair mechanically coupled to one wheel in the other wheel pair and connected therewith, to said motor, whereby movement of said wheel pairs along said tracks is virtually identical with regard to speed and direction and said shade is played out and taken up by said header motion, unfolding and folding, as said motor drives said traction wheels and propels said header along said tracks.
