A window covering includes at least one piece of sheer material and a spaced but parallel support system in the form of a second sheet of sheer material, strips of similar material or strings, with a plurality of spaced flexible vanes extending therebetween. The vanes are attached to at least the sheer sheet of material by an adhesive line that penetrates the sheer material so as to protrude through an opposite side thereof and encapsulate the fibers of the sheer material. The surface of the adhesive on the opposite side of the sheer material from the vane is roughened to create a dull appearance. Strips of fabric material which can be used as vanes are also disclosed as being formable from elongated strips of material which are lengthwise tensioned prior to applying a bonding composition to the material so as to render the strip of material more stiff in its lengthwise direction than in a cross direction.
A light control window covering comprising a first sheet of material, a second sheet of material disposed parallel to said first sheet, at least one of said sheets being porous, a plurality of strips of material each having opposed faces and opposed edge portions bordering each of said opposed faces, adhesive bonding means for bonding said strips along opposed edge portions to said sheets of material, said adhesive bonding means encapsulating the porous sheet of material and subsequently being treated to dull the appearance of the adhesive bonding means to remove any shine, the central portions of said strips forming vanes which, in a first closed position of said window covering are substantially planar and extend substantially parallel to the first and second sheets of material and, in the second open position of said window covering extend generally transverse to said first and second sheets.
A light control window covering comprising a porous sheet of material, a set of elongated elements disposed parallel to said sheet, a plurality of strips of material each having opposed faces and opposed edge portions bordering each of said opposed faces, said strips being bonded with an adhesive along opposed edge portions to said sheet of material and said set of elongated elements, the adhesive encapsulating said porous sheet of material and being treated to dull the appearance of the adhesive to remove any shine, the central portions of said strips forming vanes which, in a first closed position of said window covering are substantially planar and extend substantially parallel to the sheet of material and set of elongated elements and, in a second open position of said window covering extend generally normal to said sheet and set of elongated elements.
A light control window covering comprising a first sheet of material, a second sheet of material disposed parallel to said first sheet, a plurality of elongated flexible strips of fabric material having longitudinal and cross directions, each strip having opposed faces and opposed edge portions bordering each of said opposed faces, said strips being bonded along opposed edge portions to said sheets of material, the central portions of said strips forming vanes which, in a first closed position of said window covering are substantially planar and extend substantially parallel to the first and second sheets of material and, in a second open position of said window covering extend generally normal to said first and second sheets, wherein said strips are more stiff in their longitudinal direction than in their cross direction.
