A modified apparatus can be used to trim the width of a vertical blind having a headrail and control rods.
Claims20
An apparatus for trimming blinds of the type having a headrail, a bottom rail and a plurality of blind slats each with a predetermined profile and length, said apparatus being adapted to trim the length of said headrail and said bottom rail and said blind slats and comprising;
- a support body defining a headrail opening, a bottom rail opening, and a blind slat opening, said headrail opening being adapted to receive respectively said headrail, said bottom rail opening being adapted to receive said bottom rail and said blind slat opening being adapted to receive said blind slats, simultaneously;
- a die plate located alongside said support body;
- a headrail cutting recess in said die plate for cutting said headrail;
- a bottom rail cutting recess in said die plate for cutting said bottom rail, simultaneously with cutting of said headrail;
- die plate guide means on said support body for movably supporting said die plate, said die plate guide means defining a predetermined die plate movement axis for movement of said die plate, whereby said die plate moves relative to said headrail opening and said bottom rail opening in said support body between two positions, a first position in which said headrail and bottom rail cutting recesses are in alignment with said headrail and bottom rail openings in said support body, and a second position in which said headrail and bottom rail cutting recesses are out of alignment with said headrail and bottom rail openings in said support body thereby cutting said headrail and said bottom rail simultaneously;
- operating means for moving said die plate, between said first and second positions;
- a blind slat passage in said die plate sized with respect to said blind slat opening to allow movement of said die plate so that when said die plate moves between said first and second positions and cuts said headrail and said bottom rail said die plate does not cut said blind slats;
- a blind slat cutting means mounted on sold support body for movement relative to said blind slat opening to cut said blind slats upon movement of said blind slat cutting means, and,
- wherein said blind slat cutting means is independent of movement of said die plate.
