Abstract

An apparatus for cutting a window covering comprises a saw for cutting the window blind. A clamp assembly moves the window covering relative to the saw. A controller moves the clamp assembly to automatically position an end of the window covering relative to the saw. The saw is moved into engagement with the window covering to cut the window covering. A dust collection system comprises a shroud substantially surrounds the bottom of the saw blade where the shroud is connected to a vortex dust collector.
