An expandable and contractible tubular cell window covering includes a plurality of contiguous cells which have been bonded together to form a wavy or undulating pattern along the length of the cells. The undulating or wavy patterns can be created by initially stretching the cells before bonding adjacent cells and subsequently releasing the stretch so that the fibers engaged with the bonding medium remain in a stretched or separated condition while the remaining fibers are relaxed. The cells can also be bonded with an adhesive that expands on curing to create the same effect without having to prestretch the fabric before applying the bonding medium. In a third embodiment of the invention, adjacent tubular cells are bonded together with curved lines of adhesive which again create an undulating or wavy configuration along the length of each tubular cell. The methods for forming the window covering is also disclosed.
An expandable and collapsible window covering comprised of a plurality of elongated, transversely collapsible tubular cells bonded together longitudinally by at least one line of adhesive which extends along an area of engagement between adjacent cells, each said tubular cell having an undulate surface along its length.
An expandable and collapsible window covering comprised of a plurality of elongated, transversely collapsible tubular cells bonded together longitudinally to form a substantially sheet-like planar panel, said cells being bonded together by at least one line of adhesive which extends along a planar area of engagement between adjacent cells, each said tubular cell having an undulate surface along its length and wherein said substantially planar area of engagement lies substantially perpendicular to the plane of said substantially sheet-like panel.
An expandable and collapsible window covering comprised of a plurality of elongated, transversely collapsible, substantially non-elastic tubular cells bonded together longitudinally by at least one line of adhesive which extends along an area of engagement between adjacent cells, each said tubular cell having an undulate surface along its length.
An expandable and collapsible window covering comprised of a plurality of elongated, transversely collapsible tubular cells bonded together longitudinally to form a substantially sheet-like planar panel having a front and rear face, said cells being bonded together by at least one line of adhesive which extends along an area of engagement between adjacent cells, each said tubular cell being hollow and extending between said front and rear faces of said panel and having an undulate surface along its length.
An expandable and collapsible window covering comprised of a plurality of elongated, transversely collapsible tubular cells bonded together longitudinally by at least one line of adhesive which extends along an area of engagement between adjacent cells, each of said tubular cells being made of a single piece of material and having an undulate surface along its length.
