Abstract
This invention relates to a shade, a bottomrail therefor and a method for the manufacture thereof. The shade is pleated and has the two sections forming each rear projecting pleat secured together to form a rear projecting tab. Cord holes are formed in each of the tabs. A generally triangular in cross section bottomrail is provided which is designed to assist in offsetting and disguising the roll of the shade caused by the fabric resilience. The generally triangular bottomrail includes a housing comprised of a main body having a cavity therein and a tongue extending in a direction opposite the rear face of the shade body. The tongue has a termination point at one end opposite the main body and the housing further includes a leaf extending from the termination point of the tongue to the main body with the leaf forming a side of the generally triangular bottomrail. The housing additional includes a cord receiving arrangement mounted therein.
