Abstract
A tabbed honeycomb structure or pleated panel is made from a stack of collapsed multi-cellular material. The stack is split at bond lines thereby forming the panels of pleated or honeycomb material having a joint tab on one face. The tabbed, honeycomb material is attached between a headrail and a bottomrail to form a window covering.

A cellular shade for covering a window, said shade comprising:
- a plurality of interconnected fabric cells, wherein each cell within said plurality of cells is comprised of a nonwoven fabric and has:
- a front side and a rear side;
- a crease forming a tip on said front side;
- an upper cell wall extending from said tip and having a rear edge, said upper cell wall having an upper surface and an interior surface and having a longitudinal centerline equidistant along said upper cell wall from said tip and from said rear edge of said upper cell wall;
- a lower cell wall extending from said tip and having a rear edge, said lower cell wall having a lower surface and an interior surface, said lower cell wall and said upper cell wall being substantially equal in length;
- and
- a fin on said rear side, wherein said fin is formed by joining a first portion of said interior surface of said upper cell wall adjacent said rear edge of said upper cell wall with a first portion of said interior surface of said lower cell wall adjacent said rear edge of said lower cell wall;
- a high temperature adhesive on substantially all cells of said plurality of cells, said high temperature adhesive for connecting each cell of said substantially all cells to an adjacent cell of said plurality of cells;
- an upper rail assembly, said upper rail assembly attached to an uppermost cell of said plurality of cells;
- a lower rail assembly, said lower rail assembly attached to a lowermost cell of said plurality of cells;
- and
- a pullcord, said pullcord for raising and lowering one of said upper and lower rail assembly in relation to the other of said upper and lower rail assembly.

A cellular shade for covering a window, said shade comprising:
- a plurality of longitudinally extending, substantially parallel interconnected fabric cells, wherein substantially all cells within said plurality of cells have for each cell:
- a front side and a rear side;
- a crease forming a tip on said front side;
- an upper cell wall extending from said crease and having a rear edge, said upper cell wall having a longitudinal center line equidistant along said upper cell wall from said crease and from said rear edge of said upper cell wall;
- a lower cell wall extending from said crease and having a rear edge, said lower cell wall and said upper cell wall being substantially equal in length;
- and
- a fin on said rear side, wherein said fin is formed by joining a portion of said upper cell wall adjacent said rear edge of said upper cell wall with a portion of said lower cell wall adjacent said rear edge of said lower cell wall;
- and
- material located on at least one of said upper cell wall and said lower cell wall for attaching each cell of said plurality of cells to an adjacent cell of said plurality of cells.
