Abstract
A cell and method of manufacturing a cell for a multi-cell window covering is disclosed. The method includes the steps of providing a flexible material, stiffening a portion of the flexible material, and creating at least one control engagement formation and at least one control clearance formation in axially extending sections of the stiffened flexible material that will become an upper portion and a lower portion of the cell. The method is further defined by folding the flexible material to create a closed element and securing the flexible material to itself to maintain the shape of the closed element.

A method of manufacturing a cell for use in a multi-cell window covering comprising the steps of:
- providing a flexible material defined as an elongated member having axial and transverse directions;
- stiffening a portion of the flexible material to create at least one axially extending flexible junction;
- creating at least one control engagement formation and at least one control clearance formation in axially extending sections of the stiffened flexible material that will become an upper portion and a lower portion of the cell;
- folding the flexible material to create a closed element;
- and
- securing the flexible material to itself to maintain the shape of the closed element.
A cell for use in a multi-cell window covering comprising:
- a flexible material defined as an elongated member having axial and transverse directions, a portion of the flexible material being stiffened to create at least one axially extending flexible junction, the flexible material having transversely opposed edges that are fixed together to form a closed element;
- and
- at least one control engagement formation and at least one control clearance formation disposed in axially extending sections of the stiffened flexible material that will become an upper portion and a lower portion of the cell.
