Light control window covering and method of making same |
摘要 |
A cellular structure for window coverings has a plurality of cells formed by an upper vane and a lower vane each having a front edge and a rear edge. A C-shaped front wall has an upper end attached to the front edge of the upper vane and a lower end attached to the front edge of the lower vane to form an outwardly extending front tab at each end of the C-shaped front wall. The opposite end of each vane is attached to a rear wall. A C-shaped rear wall could be used for each cell. This structure is made by placing an edge of the vane between a pleat which is bonded to form each front tab and then preferably trimming the tab to a uniform width.
