Abstract (en)
[origin: EP0230719A2] An expandible honeycomb structure such as used for window coverings made of a foldable material which, in the expanding condition, defines a plurality of longitudinal extending cells (l4), one on top of the other. The material of each cell is adhered to the adjacent cell along at least one portion (28) in which the material is less permeable than the remainder of the material forming the cell to prevent seeping or bleeding of the adhesive.
