Combination of dual cell honeycomb structures for window covering

摘要

The combination of dual cell honeycomb structures comprises number of honeycomb dual cell units in horizontal 8-figured configuration formed of a continuous length of foldable material, then stacked and adhered to each other vertically so as to form three columns of the cell side by side. The number of dual cell units are stacked vertically and adhered to each other in such a manner that the left-hand cell of one unit is in alignment on the top of a similar left-hand cell of another unit while the right-hand cell of the one unit is in alignment on the top of a similar right-hand cell of the another unit. They are adhered to each other superposedly, to form the left- and right-hand columns of cells, respectively, and an additional central column of cells is formed between the left- and right-hand columns of cells.
