Abstract

A method and apparatus for cutting a vertical window covering are disclosed. One method of operating a window covering cutting machine comprises retaining a window covering in a package such that a first end of the window covering is located at a known first position relative to the package. An engagement element is provided on the package that is located at a known second position on the package. The engagement element is moved a distance from a saw to obtain a final dimension of the window covering where the distance is calculated using the first position and the second position.
