Abstract: A pleated construction for roll-up and pull-up window shades, and a pleated material for use as the window covering in such shades. The material comprises a facing layer of horizontally closely-pleated fabric that is tightly, adhesively bonded or fused to a backing layer of durable, pliable fabric so as to retain the pleats permanently. Preferably, the backing layer is coated or impregnated with a thermoplastic material that fuses the pleated fabric to it with the application of heat and pressure. The window covering is tacked, stapled, or adhered to a conventional spring-actuated roller or pull-up mounting apparatus and serves in the same manner as a covering made of conventional shade material. If desired, a liner may be applied to the rear side of the window covering to enhance its appearance and maintain the shape of the shade. Window coverings incorporating the subject material can be made up in any desired width and length for which facing and backing fabrics are available.
