Abstract
A method and apparatus for cutting a window covering comprises a saw for cutting the window blind. An assembly is provided for moving the window covering on the support surface relative to the saw such that the window covering is positioned to be cut by the saw. A sensor is used to automatically determine a center of the window covering by detecting a predetermined portion of the window covering such as a mark on the window covering or an edge of the window covering.
