A fabric light control window covering in which fabric vanes are adhesively bonded between two sheer fabric sheets such that relative movement between the sheer fabric sheets in a direction perpendicular to the longitudinal direction of the fabric vanes changes the angle of the fabric vanes and, thus, controls the amount of light admitted through the shade. The vanes are bonded to the sheer fabric sheets in a manner which tends to bias the sheer fabric sheets together to the nonlight admitting position. Also, disclosed are methods and apparatus for manufacturing the above window covering. The method features linear application of adhesive to the vane material which provides for a uniform appearance in the finished product. A heat setting process and apparatus is disclosed in which the bonded layers of sheer fabrics and vanes are fed between belts over hot and cool surfaces, under uniform tension and pressure. This provides for heat setting of the layers of the window covering to a uniform temperature-size relationship without inducing wrinkles or distortion into the fabric during heat setting.

We claim: 1. A panel for use with a covering for an architectural opening comprising: A sheet of fabric; at least two strings displaced from one another and positioned in a parallel plane spaced from said sheet; and a plurality of spaced, parallel and flexible, longitudinally extending, fabric vane
We claim: 1. A panel for use with a covering for an architectural opening comprising: A sheet of fabric; at least two strings displaced from one another and positioned in a parallel plane spaced from said sheet; and a plurality of spaced, parallel and flexible, longitudinally extending, fabric vanes having first and second sides, at least some of said vanes having a first longitudinally extending edge and a second longitudinally edge wherein the first side of said at least some of said vanes is attached to said sheet of fabric adjacent to said first edge, and the second side of said at least some of said vanes is attached to said strings adjacent to said second edge, said panel being movable between an open position wherein said sheet and said strings are maximally spaced from each other and a closed position adjacent to each other so as to, be spaced only by said fabric vanes, said at least some of said vanes being of S-shaped configuration when said covering is in said open position, and whereby movement of the strings relative to the sheet of fabric causes movement of said at least some of said vanes. 2. The panel of claim 1 wherein said sheet of fabric is a sheer. 3. The panel of claim 1 wherein said sheet of fabric is made from a single piece of material. 4. The panel of claim 1 wherein said attachment of said vanes to said sheet and/or said strings is with an adhesive. 5. A covering for an architectural opening comprising: a hardware system; a sheet of fabric connected to said hardware system; at least two parallel strings connected to said hardware system and spaced from one another in a plane spaced from and parallel to said sheet; and a plurality of spaced, parallel, longitudinally extending, fabric vanes having first and second sides, at least some of said vanes having a first longitudinally extending edge and a second longitudinally edge wherein the first side of said at least some of said vanes is attached to said sheet of fabric adjacent to said first edge, and the second side of said at least some of said vanes is attached adjacent to said second edge on said second side to said strings, said covering being movable between an open position wherein said sheet and said strings are maximally spaced from each other and a closed position adjacent to each other so as to be spaced only by said vanes, said at least some of said vanes being of S-shaped configuration in said open position, and whereby movement of the strings relative to the sheet of fabric causes movement of said at least some of said vanes. 6. The covering of claim 5 wherein said sheet of fabric is a sheer. 7. The covering of claim 5 wherein said sheet of fabric is made from a single piece of material. 8. The covering of claim 5 wherein said attachment of said vanes to said sheet and/or said strings is with an adhesive. 9. The covering of claim 5 wherein said hardware system includes a roller. 10. A light controlling covering for an architectural opening comprising a first sheet of material, said first sheet of material including a first texture, a second sheet of material disposed parallel to said first sheet, said second sheet of material including a second texture different from said first texture, and a plurality of substantially parallel elongated flexible strips of material secured to and extending between said first and second sheets of material, said covering being movable between an open position wherein said sheets are maximally spaced from each other and a closed position adjacent to each other so as to be spaced only by said strips of material, at least some of said strips being of S-shaped configuration when said covering is in said open position and wherein said at least some of said strips of material bias said covering toward said closed position. 11. A light controlling covering for an architectural opening comprising a first sheet of material, said first sheet of material including a first texture, a second sheet of material disposed parallel to said first sheet, said second sheet of material including a second texture different from said first texture, and a plurality of substantially parallel elongated flexible strips of material secured to and extending between said first and second sheets of material, at least some of said strips being capable of assuming an S-shaped configuration when disposed substantially perpendicular to said sheets of material and having edge portions which are secured to said first and second sheets and a central portion between said edge portions and wherein one of said edge or central portions is treated with a stiffening agent and the other of said edge or central portion is free of said stiffening agent. 12. A light controlling covering for an architectural opening comprising a first sheet of material, said first sheet of material including a first texture, a second sheet of material disposed parallel to said first sheet, said second sheet of material including a second texture different from said first texture, and a plurality of substantially parallel elongated flexible strips of material secured to and extending between said first and second sheets of material, at least some of said strips being S-shaped configuration when disposed substantially perpendicular to said sheets of material and having first and second sides, said first side being secured to said first sheet of material and said second side secured to said second sheet of material, and wherein said first and second sheets are air permeable.
