IMPROVED VANE FOR AN ARCHITECTURAL COVERING AND METHOD OF MAKING SAME

摘要

A vane (290) for an architectural covering, such as of the type used in a window openings, is designed for vertical suspension so as to resist twisting along its length. The vane (290) is constructed in a tubular configuration and may have one or more internal hollow cells. The external configuration of the vane may simulate an air foil or have other related configurations. The vanes are preferably made of a material having diagonal, dimensional stability or memory, i.e. the ability to resist stretching in a direction diagonal to the length or width of the material. A reinforcing strip can be inserted into an open end of the vane to provide a positive and durable attachment for suspending the vane from an operating system.
