Abstract

A blind cut-down apparatus for cutting and sawing a blind having at least a head rail component, and blind slats suspended from the head rail, and having a blind holding plate with an opening for holding the components in position for cutting, a slat cutting saw moveable relative to the holding plate for cutting blind components held in the holding plate, and including a movement device for moving the cutting saw and the cutting die holder. Also disclosed is a method of saw cutting ends of blind components in which the blind components are held in a head plate and in which a saw balde cuts the components.

Claims

1. A blind cut-down apparatus for cutting and sawing a blind having at least a head rail component of thin material, and blind slats of thicker material suspended from the head rail, and comprising;

a blind holding plate having at least a head rail opening and a slat opening formed therein for receiving respective components of a blind there through, and holding them in position for cutting;

a slat cutting saw moveable relative to said holding plate, for cutting blind slats extending through said holding plate;

a cutting die holder adjacent to said cutting saw, said cutting die holder carrying at least one cutting die for receiving said head rail there through, and being moveable relative to said holding plate for cutting said head rail, and,

movement means for moving said cutting saw and said cutting die holder relative to said holding plate whereby both said blind slats and said head rail may be cut in a common plane along the surface of said holding plate.

2. A blind cut down apparatus as claimed in claim 1 and including a head rail cutting die secured to said holding plate, and said head rail cutting die being mounted to said die holder, whereby said head rail cutting die may move relative to said holding plate for cutting said head rail extending therethrough.

3. A blind cut down apparatus as claimed in claim 1 and further having a saw blade guide attached to said holding plate and said saw blade being moveable therealong relative to said holding plate.

4. A blind cut down apparatus as claimed in claim 1 and in which manual movement means are provides for moving both said cutting die and said saw blade, with said cutting die holder moving a short distance, and said saw blade moving a greater distance than said cutting die holder and in a common plane therewith, under the influence of a single manual operating means.

5. A blind cut down apparatus as claimed in claim 1 and including a slat clamping mechanism operable to clamp a bundle of slats extending through said holding plate, whereby to hold them stationary during operation of said saw.

6. A blind cut down apparatus as claimed in claim 1 wherein the saw blade is operated by an electric motor, the saw blade comprising a rotatable saw disk.

7. A blind cut down apparatus as claimed in claim 1 including a cutting die guide providing a cutting die movement path which is diagonal to the movement path of said saw blade.

8. A blind cut down apparatus as claimed in claim 1 including a vacuum fan and vacuum nozzle, located adjacent to said saw blade collecting saw cut debris resulting from the operation of said saw.

9. A blind cut down apparatus as claimed in claim 1 wherein the manual operation means comprises a rotary shaft, a manual lever connected to said shaft, an operating cam connected to said shaft and engaging said cutting die holder, and a movement transmission lever connected between said shaft and said saw blade, said saw blade being operable through a path of movement greater than the path of movement of said cutting die holder.

10. The method of operating a blind cut-down apparatus for cutting and sawing a blind having at least a head rail component of thin material, and blind slats of thicker material suspended from the head rail, and comprising the steps of;

positioning said blind components in a blind holding plate having at least a head rail opening and a slat opening formed therein for receiving respective components of a blind there through, and holding them in position for cutting;

securing said components in said position;

moving a slat cutting saw moveable relative to said holding plate, for thereby cutting blind slats extending through said holding plate;

moving a head rail cuffing die adjacent to said cutting saw, relative to said holding plate thereby cutting said head rail, and,

said movement of said cutting saw and said cutting die cutting both said blind slats and said head rail in a common plane along the surface of said holding plate.

11. The method as claimed in claim 10 wherein the saw blade is mounted on a saw blade guide attached to said holding plate and wherein said saw blade guide is moved therealong relative to said holding plate.

12. The method as claimed in claim 11 wherein said movement is carried out by moving manual movement means for both said cutting die and said saw blade, with said cutting die moving a short distance, and said saw blade moving a greater distance than said cutting die and in a common plane therewith, under the influence of a single manual operating means.

13. The method as claimed in claim 12 and including the staep of clamping the blind slats in a slat clamping mechanism whereby to clamp a bundle of slats extending through said holding plate, whereby to hold them stationary during operation of said saw.

14. The method as claimed in claim 13 including the step of operating the saw blade by an electric motor, the saw blade comprising a rotatable saw disk.

15. The method as claimed in claim 14 including a cutting die guide, and inclding the step of moving the cutting die along a movement path which is diagonal to the movement path of said saw blade.

16. The method as claimed in claim 15 including the step of collecting saw cut debris by means of a vacuum fan and vacuum nozzle, located adjacent to said saw blade.

17. The method as claimed in claim 16 including the step of moving the saw blade through a path of movement greater than the path of movement of said cutting die.
