ABSTRACT:
This invention relates to a pleated shade, and a method for the manufacture thereof. The shade has two sections forming each rear projecting pleat secured together to form a rear projecting tab. Cord holes are formed in each of the tabs. The rigidity of the pleats may be substantially enhanced by providing double-weld joints for the tabs or by otherwise providing a multiple or continuous bond between the two fabric layers forming the tab. Furthermore, each section of the shade may be formed from a singly pleated section of fabric. A joint used to form a tab may also be used as a splice joint to secure together two pieces of material either for repair of a defective or damaged material, to achieve a desired aesthetic effect or to customize the length or width of the shade. Pleat reversal problems may be overcome by carefully selecting the relative size of the tab and shade sections, by controlling the size and tab positions of cord holes, and by treating the nose pleat to improve its memory. A second piece of material may be positioned behind the first. The second piece of material may have tabs formed in the same manner as the first piece, the pieces of material being hung with the tabs facing each other, and the tabs may be maintained at a predetermined relative position. If the second piece of material is shorter than the first and tabs are simultaneously formed on the two pieces, a prismatic configuration may be achieved.
