<p>An actuator device is provided for use in a view-through window covering having a plurality of cells. The actuator device includes at least one cooperating pair of control members including a first control member that engages an upper portion of each cell and a second control member that engages a lower portion of each cell. The cooperating pair of control members are engaged with the cells along a plane parallel to the plane of the window covering, whereby relative movement of the control members modifies the size of the space between the cells. A cell and method of manufacturing a cell for a multi-cell window covering is also 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.</p> |
