Abstract

A method for manufacturing a window covering for an architectural opening is disclosed. The covering including a support, at least one vane, and at least one operating element. The method for manufacturing the covering includes extending the vane across the support; extending the operating element along a length of the support, and coupling the covering to a roller for selective rotative movement for extending and retracting the covering during use. The operating element being movable with respect to the support. In use, an upper portion of the vane is fixed with respect to the support while a lower portion of the vane is fixed with respect to the operating element so that the lower portion of the vane is movable relative to the upper portion by moving the at least one operating element.

First claim

We claim:

1. A method for manufacturing a covering for an architectural opening, the covering including a support, at least one vane, and at least one operating element, said method comprising:
extending a vane of the at least one vane across the support;
extending the at least one operating element along a length of the support, the at least one operating element to be movable with respect to the support; and
coupling the covering to a roller for selective rotative movement for extending and retracting the covering during use;
wherein:
an upper portion of the vane is fixed with respect to the support;
a lower portion of the vane is fixed with respect to the at least one operating element; and
the lower portion of the vane is movable relative to the upper portion by moving the at least one operating element.

2. The method of claim 1 , further comprising bonding, by a bonding bar, the upper portion of the vane to the support and the lower portion of the vane to the at least one operating element.

3. The method of claim 2 , wherein the upper portion of the vane is bonded discontinuously to the support.

4. The method of claim 3 , wherein the bonding bar applies at least one of heat and pressure discontinuously to the vane along a width of the support.

5. The method of claim 4 , wherein the bonding bar includes at least one gap defined therein, the at least one gap does not apply the at least one of the heat and pressure to a width of the vane.

6. The method of claim 1 , further comprising securing the at least one operating element to a length of a tape.

7. The method of claim 6 , wherein securing the at least one operating element to the length of the tape includes activating an adhesive on the length of the tape.

8. The method of claim 7 , wherein activating the adhesive comprises applying at least one of heat and pressure to the length of the tape.

9. The method of manufacturing of claim 1 , further comprising cutting, by a shearing mechanism, the vane so that the vane has a width equal to a width of the support.

10. The method of claim 1 , wherein prior to extending the vane across the support, storing by an accumulator the vane to prepare the vane to be extended across the support.

11. The method of claim 1 , wherein the operating element comprises a cord or filament.

12. The method of claim 1 , wherein the support comprises a support sheet.

13. The method of claim 1 , wherein the support comprises one or more strips of material operably connected together.
