  • Patent number: 5355928
    Abstract: A Roman shade having a plurality of rearwardly extending vertically spaced horizontal pleats uses plastic retaining means adhesively bonded to the outer surfaces of the pleats and eyelets to precisely and durably maintain the pleats. The shade includes bodies of flexible facing and backing materials integrally segmented by folding portions of the material into pleat segments to form the pleats. Plastic strips having vertically aligned openings are adhesively secured to the outside surfaces of the pleats and interconnected by eyelets extending through the openings. Engaging surfaces of the eyelets engage the plastic strips further securing strips to the pleat outer surfaces. Edge borders of facing and backing material formed of back folded edge portions of said facing and backing material adhesively secured to itself, combined with disclosed pleat design, obviate need for sewing during construction.
