A method for manufacturing a window covering for an architectural opening. The method includes operatively coupling a support material and at least one operating element to a roller for selective rotative movement during use. The at least one operating element extending along at least a part of the length of the support material. The method also includes extending a plurality of vanes relative to the support material. Each vane including an upper edge and a lower edge, wherein the upper edge of each of the vanes is fixed against movement relative to the support material, the lower edge of each of the vanes is fixed against movement relative to the at least one operating element, and the lower edge of each of the vanes moves relative to the upper edge of each of the vanes by moving the at least one operating element.

Apparatus and method for making a window covering having operable vanes

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.

Method for making a window covering having operable vanes

An apparatus and associated method for manufacturing a window covering for an architectural opening. The apparatus includes a support structure handling assembly, an operating element handling assembly, and a vane handling assembly. The handling assemblies process the respective materials to an assembly station to attach one portion of a vane to the operating elements, and another portion of the vane to the support structure, allowing movement of one portion of the vane relative to other portion of the vane.

A method and apparatus for creasing planar material includes a pair of confronting drums between which the material is passed with at least one of the drums having at least one electrical filament thereon adapted to engage the planar material as it is passed between the drums for melting the planar material to a predetermined depth. The filaments are preferably quick heating and also dissipate heat quickly so that they can be activated and deactivated in short intervals so that the drums upon which the heat filaments are mounted do not heat up between the filaments.
