ABSTRACT:
A machine for forming a bottom rail and a valance for a window blind unit. The machine has a support member upon which a length of wood ultimately destined to be a bottom rail or a valance can reside while cutting occurs, and includes at least one laterally movable saw blade for cutting a selectable wood segment at a selectable angle up to 90.degree.. Such angular cutting permits a mitred junction of corners in a formed valance. The machine also has at least one wood boring device and at least one wood drilling device to provide for pull cord anchoring whereby cords are passed through a drilled aperture and knotted such that the knot is housed in a bored compartment. The machine can be incorporated and automated for inline inclusion with automated components of a window blind manufacturing and assembly system to provide finished bottom rails and packaged valance components for final installation at a site of use.
