Claims
- 1. The method of making a pleated blind having hingably attached to pleat troughs thereof a plurality of slats, said method comprising demarcating on a sheet of shading material transverse lines of fold and areas to receive adhesive-stiffener coating, applying said adhesive-stiffener, and folding said sheet along a first set of said lines to acquire expandable pleats in non-adhesive areas and along a second set of lines to acquire cojoined adhesively bound pleat-trough extensions in and about one-half the width of the adhesive areas.
- 2. The method of claim 1 wherein said folding step further comprises form folding said pleat-trough extensions to acquire cambered surfaces therefor during the adhesive-set period.
- 3. The method of claim 1 wherein said folding step further comprises cutting along the lines of said second set and inserting for adhesion between the adhesive-applied sections of slat extensions additional pre-shaped slat elements so that said slat elements will be captured and adapted thereby as additional continuous trough-slat extensions.
- 4. For an extended, variably light-filtering, insulative curtain that comprises continuous pleated fabric and is adjustable between an extended light-filtering position and a collapsed position, wherein said pleated fabric defined an array of pleats having front-facing crests and rear-facing troughs when in said extended position and wherein said troughs are joined at common lateral edges so that a multiplicity of parallel slats are arrayed behind and attached to said pleated fabric, a front edge of each slat hingably connected to and along the common latreal edge of a trough of each of said pleats so that actuation means may be employed to urge the rear edge of each of said slats toward and into contact with an adjacent slat forming therebetween said contacting slats and their common lateral trough edges an insulative sleeve, the method of making said curtain comprising the steps of creating pleatings in a sheet of shading material while stiffening discrete portions of the pleated material and immediately thereafter joining said discrete portions to themselves in order to form the slats of said curtain, said slats extending articulatively because of said joining from the troughs of said pleats.
- 5. The method of claim 4 wherein said stiffening step further comprises determining said discrete portions of a pleat relative to the pleat crest, defining said portions as trough extensions and lengthening said extensions as deemed necessary to create slats of specific width.
- 6. The method of claim 5 wherein said stiffening step further comprises stiffening and cojoining the folded portions of said trough extensions by applying suitable adhesive thereto.
- 7. The method of claim 5 further comprising shaping and stiffening said lengthened extensions into desired cambered shapes of slats.
