Apparatus for the manufacture of blinds of the type having a headrail, a plurality of ladder tapes suspended from said headrail, a plurality of blind slats supported by said ladder tapes, and raise cord means passing through openings in said blind slats, whereby said blind slats may be drawn upwardly toward said headrail, and said apparatus comprising;

• at least two blind slat material supply means adapted to supply at least two strips of blind slat material along parallel spaced apart blind slat paths;
• die support means defining at least two elongated pathways along at least two predetermined axes for passage of said at least two strips of slat material therealong parallel to one another for the formation of said blind slats from one or other of said at least two strips;
• a plurality of die means mounted on said die support means in at least two groups on respective said paths at least some of said die means being moveable therealong, said die means in each said group being aligned with one another along respective said pathways for receiving respective said strips of said material side by side in spaced apart relation;
• die operating means operable to procure simultaneous operation of selected ones of said die means in respective said groups;
• strip threader means, located downstream of said die support means, for supporting said ladder tapes and defining a predetermined treading path for threading a said strip through said ladder tapes;
• moveable mounting means supporting said threader means whereby said threader means may be aligned with a selected one of said strip paths, and,
• power operated movement means connected to said threader means, whereby said threader means may be moved on aid mounting means between at least two predetermined positions.

• die support means defining a predetermined axis for passage of strip material therealong for the formation of said blind slats;
• a plurality of die means mounted on said die support means, at least some of said die means being moveable therealong, said moveable die means including a first moveable die means, and a plurality of subsequent moveable die means, said die means being aligned with one another along said axis whereby a said strip of said material may pass therealong;
• first moveable die movement means connected to said first moveable die means and operable to move said first moveable die means a first predetermined distance;
• means interconnecting said first moveable die means and its next adjacent said subsequent moveable die means;
• respective further moveable die connection means connecting between respective further subsequent moveable die means in series whereby movement of said first moveable die means for said first predetermined distance caused by said first moveable die movement means is communicated to all of said subsequent moveable die means such that each of said moveable die means moves a distance different than that moved by its adjacent said moveable die means, whereby at least selected ones of said moveable die means may be precisely positioned along said support means;
• die operating means operable to procure selective simultaneous operation of selected ones of said die means while leaving others of said die means inactive;
• die control means for selecting those said die means to be operated whereby to form openings in said strip material at preselected spaced points therealong by operation only of those said die means selected by said die control means;
• cut off die means for cutting off a preselected length of said strip material to form a said slat for a said blind, and,
• slat threader means, located downstream of said die support means, for supporting said ladder tapes and defining a predetermined slat threading path for threading a said slat through said ladder tapes.
